at 240V AC and 10A, (DC13 rating) at 24V DC.
Benefits and features
User friendliness and safety
Flexibility
• Positively driven contacts
• Choice of auxiliary contacts
3TH30 contactor relays comes with 4 contacts as a basic unit
(4NO, 3NO+1NC, 2NO+2NC). However the contacts can be
extended upto 8 contacts by adding maximum 4 auxiliary
contact blocks to this basic unit. This offers flexibly in selection
and configuration.
• Choice of mounting
3TH30 auxiliary contactors satisfy the conditions for positively
driven operation between NO and NC contacts. NO and NC
contact do not close at the same time. This is extremely
important when they are used in safety circuits of critical
applications. This ensures operator safety even during
abnormal condition.
• SIGUT Termination
3TH30 can be mounted on 35mm DIN rail and they are also
suitable for screw mounting.
Long Life
– Figure touch proof terminals
It protects against accidental contact with live parts which
ensures operator safety.
Superior design of current carrying parts, contact system and the
magnet system increases the reliability which also results into
higher electrical and mechanical endurance.
– Funnel shaped cable entries
High reliability
– Cable end-stop
• Double Break Parallel Bridge contact mechanism
This mechanism is available with 3TH30. Such contact
mechanism ensures reliable contact at low voltage and low
currents (5mA at 17V DC). It also offers unmatched reliability
as well as capability to integrate directly into PLC or
instrumentation circuits.
Reduce wiring time by facilitating quick location of the
connecting wire.
It decides the insertion depth of the connecting wires. Since
the insertion depth is predetermined, insulation of the cable
can be cut accordingly and the possibility of insulation
getting inadvertently caught under the terminal is avoided.
– Captive Screws
This feature prevents the screws from falling down thereby
facilitates the wiring. Hence, the auxiliary contactors are
delivered with untightened terminals. This eliminates the
operation of untightening terminals before wiring.

High performance
• No duration upto 55°C
Contactors are suitable for operation in service temperature
upto 55°C without derating. This avoids selection of higher
rated contactor, thereby reducing cost.
• Long Life
Superior design of current carrying parts, contact system and
the magnet system increases the reliability results into higher
electrical and mechanical endurance.
• Positively driven contacts
3TF contactors satisfy the conditions for positively driven
operation between the main power contacts and the NC
contacts. NC contacts positively open before the main contact
closes. This is extremely important when power contactors are
used in safety circuits of critical applications.
• SIGUT Termination
• High short-time rating
Contactors have a high short-time rating, which makes them
suitable for applications having high starting currents and long
run-up times.
High reliability
• High insulation voltage and impulse withstand voltage capacity
ensures reliable performance during occasional abnormal
increase in supply voltage.
• Double break parallel bridge contact mechanism
This mechanism is available for auxiliary contacts. Such contact
mechanism ensures reliable contact at low voltage and low
currents (5mA at 17VDC). It also offers unmatched reliability.
(Chances of 2 mal-operations in 100 mill. operations as against
4460 for single bridge contacts)
– Figure touch proof terminals*
It protects against accidental contact with live parts which
ensures operator safety.
– Funnel shaped cable entries

Surge suppressor (Varistor) for 3TF46-56
1. Mechanical interlocking kit
Mechanical interlock is required when the supply from two
different sources is available. Also the same is required for the
application involving reversing of motor. Here two contactors
are mechanically interlocked with the help of mechanical
interlock kit. This ensures closing of only one contactor at a
time. Thus prevents a short circuit upon load changeover from
one contactor to another.

2. Surge suppressor
It is used to reduce the effect of switching overvoltages created
during the opening of inductive circuits. Typically they are
mounted outside the body of the contactor, and are connected
in parallel with the coil terminals. Various techniques for the
suppression of switching overvoltages can be employed. For
example: RC element, Varistor etc.

3. Connector
The 3TS90 connector is used to mount the motor protection
circuit breaker 3VU on the contactor 3TF with screw terminals.
It enables mechanical and electrical connection between
contactor and motor protection circuit breaker.
RC Element:
RC element
The effective increase in the capacitance of
the coil circuit reduces the amplitude and rate
of rise of switch off overvoltage spikes to such
an extend that no rapid restriking occur.
Varistor:
Varistor limit the maximum value of the
overvoltage because they become highly
conductive above a threshold value. Until this
threshold value is reached shower discharge
occurs for small duration.

Contact life calculation:
Contactors have bounce free operation. Electrical life is influenced
by the breaking currents. For normal AC3 duty the breaking
current is the rated operational current and for AC4 duty, the
typical breaking current is 6 times the rated operational current. In
case of mixed duty, the expected life is determined as under
Where
X = expected life for mixed duty
A = expected life for normal AC3 duty
B = expected life for 100% AC4 duty
C = proportion of inching operations as a percentage of total
operations.

Contactors for Hoisting Duty
AC slipring motors are most commonly used for the hoisting applications. AC2 duty pertains to starting
and switching off the slipring motors. In case of hoisting duty breaking current is the starting current
and frequency of switching is high.
The table shows the making and breaking capacity at normal and
at hoisting application where Ie indicates the rated full load
current.

Application
AC-2 operation is the typical duty for starting and switching off
fully-loaded slipring motors in the starting phase. The rating of
the contactor, to switch the motors, is selected primarily on the
basis of rated make & break capacity and desired electrical
endurance.
Standard
The contactors comply with the “Regulations to low voltage
switchgear” of DIN VDE 0660 and IS/IEC 60947-4-1.
Range
Hoisting duty contactors are available from 110A to 400A
(AC2/AC3 rating).
Benefits and features
Operator safety
• Arc Chamber Interlock
It prevents the contactor from switching ON, if the arc chamber
is not fitted properly. Thus avoids accidents to plant and

When 3 conducting paths are connected in parallel, the maximum load current rises to 2.5 times the value given in this table. When 2 conducting paths are
connected in parallel, it rises to 1.8 times the value given in this table.
B. Selection of contactors for contact endurance: with normal
and inching operation
C. Selection of contactors for contact endurance: with mixed
operation
Contactors suffer more erosion during inching operation than
when stopping motors from a steady speed, i.e. normal
operation. With slipring motors the starting current can be up to
2.5 times the rated current of the motor which means that this
current has to be broken when inching is taking place. During
normal operation, on the other hand, only the rated current has to
be broken under full-load; under part-load it is even less.
Determining contact endurance from AC-2 duty (Ic = 2.5 x Ie) will
only give correct results when 100% inching operation is
involved.
When mixed operation is involved, i.e. primarily breaking of the
motor rated current but with some breaking of higher currents
due to inching, the endurance of the contacts can be calculated
approximately from the following equation:

D. NOMOGREM
Apart from knowing the figure for contact endurance in operating cycles, users are also interested to know what period of time this
amounts to before the contacts have to be changed. The value can be ascertained from the nomogram in Fig. 3. using the Nomogram
Fig. 3 Nomogram for determining contact endurance in year (250 working days) and months with daily operating hours of 4, 8, 12, 16, 20 and 24 h.
27
Draw a line from the point on the left-hand scale indicating the
required number of operating cycles to the point on the right
hand scale indicating the required number of operating cycles per
hour. Then, from the point where this line intersects with the
centre axis, draw a horizontal line to the left or right scale for the
actual number of daily operating hours.
Note: If a figure of 365 days per annum is being employed instead
of 250, the total operating time obtained from the nomogram
must be multiplied by 0.68.
Dimensional drawing
The “Hoisting Duty” Contactors are mechanically similar to our
existing 3TF power contactors. Therefore they have exactly same
dimensions as the corresponding 3TF power contactors.
Please refer page nos. 21 and 22.
Useful technical information
Starting method of Slip ring motor (AC2 duty):
Example:
Service requirements: 1.4 million operating cycles endurance,
200 operating cycles per hour, 16 hours service per day.
Three types of the contactors are used to control the three
phase slip-ring motors: the stator contactor, the acceleration
contactor and the rotor short circuit contactor.
Result:
Stator contactor
Initially the stator contactor (K1) is closed to energize the motor.
None of the rotor contactor (K2 or K3) is closed yet. Hence all the
resistances are present in the rotor circuit. The starting current
can reach to 1.5 to 4 times of the rated operational current. The
AC2 rating of the stator contactor is selected as per the load factor
of the motor.
Total operating time approx =18 months.

Acceleration contactor
Now acceleration contactor (K2) is closed which short circuits the
resistances (R1). The sizing of this contactor (K2) is as per AC1
rated operational current. The current flow time per cycle and the
number of cycles per hour has to be considered for the selection.

Rotor short circuit contactor
At the end, the rotor short circuit contactor (K3) closes, short
circuiting the last resistance bank (R2) thus remove all the
resistances from the rotor circuit. The starting period is hence
completed. The duty of this contactors is characterized by the
small closing stress. the decisive factor is the thermal stress. The
duty factor is considered while finding out the permissible values
of the rated operational rotor current for rotor contactors.
Picture below shows the acceleration (K2) and the rotor short
circuiting contactor (K3) in the delta connection. If they are
connected in star then the ratings are reduced by 35%.
AC1 Duty Contactors 3TK5
When contactors are not required to make or break current but only carry the current, the contactors
can be used to its full AC1 rating. Siemens 3TK5 AC1 duty contactors can be offered in such cases.
Application
3TK5 AC1 duty contactors are widely used in sugar mills, DC
drives and changeover applications. Also they can be offered for
the applications like switching resistive loads, battery charging etc
where the AC1 rating of the contactor is suitable.
Standards
3TK5 contactors conform to IS/IEC 60947-4-1. They also carry the
CE mark.
Range
3TK5 AC1 duty air break contactors are available from 190A (AC1)
to 500A (AC1) in 3 pole version.
Benefits and features
High performance
• No duration upto 55°C
SICOP contactors are suitable for operation in service
temperature upto 55°C without derating. This avoids selection
of higher rated contactor, thereby reducing cost.
• Long Life
Superior design of current carrying parts, contact system and
the magnet system increases the reliability results into higher
electrical and mechanical endurance.
• Positively driven contacts
3TF contactors satisfy the conditions for positively driven
operation between the main power contacts and the NC
contacts. NC contacts positively open before the main contact
closes. This is extremely important when power contactors are
used in safety circuits of critical applications.

Bimetal Overload Relays 3UA and 3UC
The 3UA / 3UC thermal overload relays are suitable for customers from all industries, who want
guaranteed optimum inverse time delayed protection of their electrical loads. The relays meet the
requirements of IS/IEC 60947-4-1.
Application
1
3UA overload relay: 3UA5/6 are 3 pole adjustable bi-metal
overload relays mainly suitable for normal starting applications.
They provide accurate and reliable protection to motors against
overload as per CLASS 10A. They also offer protection against
single phasing and unbalanced voltages.
3UC overload relay: 3UC5/6 are 3 pole adjustable, saturable CT
operated bi-metal overload relays mainly suitable for heavy
starting applications (i.e. when heavy masses are to be put in
motion resulting in larger starting period). They provide accurate
and reliable protection to motors against overload as per CLASS
30. They also offer protection against single phasing and
unbalanced voltages.
If single-phase AC or DC loads are to be protected by the 3UA /
3UC thermal overload relays, all three bimetal strips must be
heated. For this purpose, all main current paths of the relay must
be connected in series.
Standards
Bimetal relays conform to IS/IEC 60947-4-1. They also carry the CE
mark.
Range
3UA5: 0.1 to 120A, (Class 10A, without CT)
3UA6: 85 to 630A, (Class 10A, CT operated)
3UC5/6: 2.4 to 400A (Class 30, CT operated)
Relay overview
Overload relay operates on the bi-metallic principle. The heater
winding wound on the bimetal strips carry the current flowing
through the motor. In case of overload, the current carried
through the heater winding is more than the rated current. This
heats up the bimetals. Due to this bi-metal strips bend and open
the NC contact of the relay, which is connected in the control
circuit of the contactor, thus disconnects the motor from the
supply. The tripping time is inversely proportional to the current
flowing through the bi-metal strips. Bi-relays are therefore,
referred to as “current dependent” and inverse-time delayed
relays.

1. Connection for mounting onto contactors:
Optimally adapted in electrical, mechanical and design terms
to the contactors, these connecting pins can be used for direct
mounting of the overload relays. Stand-alone installation is
possible as an alternative (in some cases in conjunction with a
stand-alone installation module).
2. Selector switch for manual/automatic RESET (blue):
With this switch you can choose between manual and
automatic RESET. A device set to manual RESET can be reset
locally by pressing the RESET button. A remote RESET is
possible using the RESET modules (accessories), which are
independent of size.
3. TEST button (red):
Trip circuit can be manually checked by using this button.
During this simulation the NC contact (95-96) is opened and
the NO contact (97-98) is closed. This tests whether the
auxiliary circuit has been correctly connected to the overload
relay. The relay must be reset with the RESET button if it has
been set to manual RESET. If the thermal overload relay has
been set to automatic RESET, then the overload relay is
automatically reset when the TEST button is released.
4. Motor current setting dial:
Setting the device to the rated motor current is easy with the
large rotary knob. (Recessed dial, hence no possibility of
accidently change in current setting.)
5. Trip indicator (Green):
A separate mechanical Green Trip Indicator is provided on the
front cover of the relay to indicate the tripped state of the
‘manual reset’ relay.
33
Recovery time
After tripping due to overload, the thermal overload relays require
some time until the bimetal strips have cooled down. The device
can only be reset after the bimetal strips have cooled down. This
time (recovery time) depends on the tripping characteristics and
strength of the tripping current. The recovery time allows the load
to cool down after tripping due to overload.
Benefits and features
High performance
• In-built single phasing protection
for -25 to 55° C. For this purpose the relays are temperature
compensated between service temperatures of -25° C to
+55° C.
User friendliness and safety
• SIGUT termination Technique
– Shrouded auxiliary terminals
Increases safety, as they protect against accidental contact
with live parts.
– Funnel shaped cable entries
Reduce wiring time by facilitating quick location of the
connecting wire.
– Cable end-stop
They decide the insertion depth of the connective wire. As
the wire cannot now protrude into the relay housing, it does
not hamper the movement of the auxiliary contacts. Since
the insertion depth is predetermined, insulation of the cable
can be cut accordingly and the possibility of insulation
getting inadvertently caught under the terminal, is avoided.
– Captive Screws
This feature prevents the screws from falling down thereby
facilitates the wiring. Hence, the relays are delivered with
untightened terminals. This eliminates the operation of
untightening terminals before wiring.
– Lug less termination
This feature helps in reducing the termination time.
In case of phase loss the current through the other two
windings increases by 1.732 times the rated current of the
motor. The current now flows only through the 2 bimetallic
strips which should produce the required force on the tripping
mechanism. This needs higher currents for longer time. As
current is not too high so the relay might take higher time to
trip. This can cause damage to the motor. Similar condition
happens in case of phase unbalance. To take care of these
conditions our birelays are constructed such that they offer a
built-in single phasing protection using differential slider
principle.
• Temperature compensation
The temperature compensation feature reduces the effect of
the ambient temperature on the tripping behavior. This ensures
the minimum tripping current lies within the specified range
34
– Screw-driver guides reduce wiring time as they allow the
use of power screw-drivers.
Flexibility
• Potential free Auxiliary Contacts
Potential free 1NO + 1NC contact arrangement is provided as a
standard feature. The 1NC contact is used in the control circuit
of the contactor for disconnecting the motor in case of
overload, whereas the 1NO contact can be used for various
applications such as indication.
• Mounting
3UA5: suitable for direct mounting or independent mounting
(with the help of independent mounting accessory)
3UA6 and 3UC5/6: suitable for Independent mounting.

Characteristic Curves
Tripping characteristics
The current/time curves show the relationship between the
tripping time from cold state and multiples of the set current Ie.
When the relay is at operating temperature and carrying 100 % Ie,
the tripping times are reduced to approximately 25 %. Tripping
curve is applicable to 3-pole loads and 2-pole loads. For singlepole loads, the tripping curves lie between curves of 3-pole loads
and 2-pole loads.
For normal operation, all 3 bimetallic strips of the overload relay
must be heated. The overload relays 3UA / C are suitable for
protecting motors with phase control. For protecting single-phase
or DC-loads, therefore, all three main conducting paths must be
connected in series. Tripping curve for 3 pole loads is then
applicable. The release current with a 3-pole symmetrical load is
between 105 % and 120 % of the set current.
The above curves are the general characteristics curves; for individual characteristics curves of each rating, please contact our nearest
sales office.

Motor Protection Circuit Breakers
3VU13 and 3VU16
3VU13/3VU16 is suitable for use in fuseless motor feeders upto 11KW/22KW (25A/63A) respectively. 3VU
motor protection circuit breakers are used for protection of motor against overload, single phasing and
short-circuit faults.
Applications
• Motor Protection
Circuit breakers type 3VU13 & 3VU16 offer overload, short
circuit and phase loss protection for 3 phase motors upto 11kW
and 22 kW respectively. The breaker has a toggle switch for
ease of operation and can be offered with auxiliary contacts,
trip indicating contacts, U/V or Shunt release. High breaking
capacity of 100kA is available in 3VU13 upto 6A and in 3VU16
upto 25A.
• Distribution Feeder Protection
Standard version of 3VU13 and 3VU16 has adjustable O/L and
fixed S/C release. Main application is for disconnection and
protection of the distribution feeders, upto 25A and 63A
respectively. A large number of overlapping ranges are
available for offering closer protection to various loads.
• Transformer protection
A separate 3VU13 range can be offered to protect the primary
side of the transformers. The range is available upto 20A. To
take care of the inrush current due to transformer switching,
the S/C release is set at 19 times the rated current unlike 12
times of the rated current available in standard range.
• Fuse Monitoring
3VU1340-1MS00 is offered for Fuse Monitoring application.
This device is connected in parallel to the fuses. In case one of
the fuses blows, the rated current will flow through the
corresponding phase of this MPCB. MPCB, through its auxiliary
contacts, provides a tripping signal to the contactor and thus
the motor will be switched off. Hence, the motor will be
protected from single phasing. (Refer page 51 for connection
diagram)

Benefits and features
High performance
• Instantaneous Tripping
3VU circuit breakers operate on the Current Limiting
Principle.
Current Limiting Principle
In case of short-circuit condition motor protection circuit
breaker trips before the short-circuit current reaches the
prospective peak. Hence, for circuit breaker to be current
limiting it must interrupt the short-circuit current in half cycle
or less as shown below.
Fuse Monitoring MPCB - 3VU1340-1MS00
45
Current Limiting is achieved in 3VU as follows
In case of a short circuit, the contacts are opened electrodynamically by the short circuit current. The instantaneous
overcurrent release, through the switching mechanism, trips all
the three poles of the breaker. A large arc voltage is quickly
built up in the arc chamber limiting the short circuit current.
Thus ensures faster fault clearing.

• Ambient temperature compensation upto 55 C hence no
deration required upto 55oC.
Safety
• Trip Free Mechanism
The breakers have a trip-free mechanism. Even by holding the
toggle, tripping operation can not be stopped or blocked once
it is started. Thus ensure positive opening in the event of fault.

Accessories:
RHS
Alarm contact
(1NO + 1NC)
When short circuit (and not overload) occurs, alarm contact 1NO+1NC changes over which can be used to give
indication. We need to reset it manually after clearing of short circuit. It performs a function of reclosing lockout.
and/or
LHS
Auxiliary Contact
(1NO + 1NC)
This contact can be added to the MPCB with or without built -in 1NO+1NC contact.
Shunt Release
Shunt trip is used for remotely tripping the MPCB.
Undervoltage Release

Diagram for 3VU13/16 and current limiter (applies for 3VU13 only)
The breaking capacity of 3VU13 is 100kA upto 6A. However for
3VU circuit breakers with rated current of 8A and 10A the shortcircuit breaking capacity is 10kA. For circuit breakers with rated
current from 16A to 25A the short-circuit breaking capacity is 6kA.
In order to enhance the breaking capacity to 50kA, for these
ratings (8A to 25A), the current limiter can be used. Thus the
need of back up fuses is obviated.
The current limiter is connected in series with 3VU13 MPCB.
When a short circuit occurs, the limiter trips and in turn opens the
downstream MPCB. The auxiliary contacts of the current limiter
(1NO+1NC) can be used for signaling whether the limiter has
tripped or not.
Several MPCBs can also be connected at the output of a current
limiter. However the summation of current ratings of individual
MPCBs should not be greater than 56A.

Starters
Overview
Siemens caters with following types of starters to agricultural and industrial sector.
55
Application
Benefits and features
The main purpose of motor starters is to start the electrical motor
by switching ON the contactor inside the starter. The relay inside
the starter additionally protects the motor in case of overload and
single phasing condition. The starter is nothing but a pre-wired
assembly of contactor(s), relay and ON-OFF push buttons. Direct
on line and star delta are two methods of starting the electric
motors which is achieved by our DOL and star delta starter
respectively.
Flexibility
• Starters with or without enclosure
Pre-wired DOL as well as star delta starters are available either
in open execution or in sheet steel enclosure.
Standard
• Industrial starters without relay
Industrial DOL as well as star delta starters have provision for
mounting relay but the relay is not provided in the starter. Thus
offering flexibility of selecting 3UA relay range as per
customers requirement.
Siemens starters confirms to IS/IEC 60947-4-1
Reliability
Range
Agricultural starters
3TW42 DOL starters (A1, A2, A3, A4): upto 10Hp
• Wide band coil voltage
Agricultural DOL starters are having option of 200-400 V and
agricultural star delta starters are having option of 230-400 V
coil voltage which takes care of wide fluctuations in the supply
voltage occurring especially in the remote places.
3LW42 Handle operated star delta starters (B1): upto 15Hp
High performance
3TS02 Semi-automatic and 3TE02 fully automatic star delta
starters (B2, B3, B4): upto 25Hp
• In-built single phasing protection
In case of phase loss the current through the other two
windings increases by 1.732 times the rated current of the
motor. The current now flows only through the 2 bimetallic
strips which should produce the required force on the tripping
mechanism. This needs higher currents for longer time. As
current is not too high so the relay might take higher time to
trip. This can cause damage to the motor. Similar condition
happens in case of phase unbalance. To take care of these
conditions our birelays provided in the starters are constructed
such that they offer a built-in single phasing protection using
differential slider principle.
Industrial starters
3TW04 DOL and 3TE04 star delta starters (C1, C2): upto 75Hp

Useful technical information
Method of starting
A. DOL starting method:
Bimetal Overload Relay:
The RAJA direct-on-line starter is fitted with 3UW50 relay. These
relays are computer calibrated and therefore, offer accurate
protection. The main benefit of this bimetal relay is the built-in
single phasing protection in addition to the overload protection.
This relay is automatic reset type and can not be reset by hand.
Push buttons
Push buttons are used for switching ‘ON’ and ‘OFF’ the starter.
Operation:
The most economical and popular method of starting squirrel
cage induction motors, is direct-on-line, where the starter is
connected directly across the supply. However, the starting
current at the moment of switching Direct-on-line can be as high
as 6-8 times the rated current.
In DOL starting, the ‘ON’ push button is pressed, which energizes
the contactor coil, thus switching on the circuit. When the OFF’
push button is pressed, the contactor is de-energized, switching
off the circuit. The bimetal relay under normal functioning of
motor plays no active part in the starter. But under overload,
single phasing or locked rotor conditions of Motor, the bimetal
relay cuts-off the supply to the contactor coil, tripping the circuit.
The contactor itself provides the necessary ‘no-voltage’ protection
in so far as it will drop out in the case of a supply failure, and for
restarting on resumption of supply, the ‘ON’ push button will have
to be pressed again.
A2. RAJA DOL stater in open execution:
Advantages: High starting torque, shorter starting time, simple
construction and wiring, space saving etc.
Disadvantages: High starting current
Types:
Agricultural Starters
A1.
RAJA DOL starter
Construction
This starter is exactly same as DOL starter with sheet steel housing
except the enclosure and push buttons. The contactor and
birelays are wired and mounted on the plate. It is expected that
the user provides for the housing for this starter and also for the
ON-OFF arrangement by way of push buttons or any other means.
A3. RAJA DOL starter with hand reset:
This starter is exactly same as RAJA DOL starter with sheet steel
housing but in this case the relay needs to be reset manually. The
OFF button on the housing is also used as reset button for
resetting the relay after overload.
Contactor:
The DOL starter up to 10 HP is fitted with 3TW02 contactor. This
contactor is specially designed by Siemens considering the
requirements of industry as well as agriculture. Considering the
specific need of the agricultural pump set applications, Siemens
has designed a special wide band coil (200- 400V). This coil
operates reliably even when there is wide voltage fluctuation. The
contact rating of this contactor is 20 A. This high contactor rating
has made RAJA starter the most suitable starter for applications
where current for given HP is higher than that of the conventional
motors’ e.g.. Submersible pumps etc.
65
In this starter, the changeover from ‘star’ to ‘delta’ is done
manually through a control switch.
A4. DOL starter with lockable off:
Construction:
It consists of a star-delta switch (3LAO), contactor (3TW02), an
overload relay (3UW50), “Reset” push button and a safety ‘ON’
push button.
Operation:
This starter is exactly same as RAJA DOL starter with sheet steel
housing but the relay needs to be reset manually by pressing OFF
PB. Locking arrangement is provided for OFF push button; so
starter can’t be switched ON, inadvertently.
B. Star delta starting method:
In star delta starting, initially the motor windings are connected in
star. This reduces the starting current by 1/3 rd of the full load
current also the voltage by (1/√3) of the rated value. As the torque
is proportional to the square of the voltage, the starting torque
also get reduced to 1/3 rd of it’s full load value. Once the motor
attains approximately 80% of the rated speed, the windings get
connected in the delta formation.
To start the motor, move the 3LAO switch handle from ‘O’ position
to ‘star’ (Y) position with the right hand and press the start’ - (I)
push button with your left hand. The motor starts and when it has
almost come to its rated speed (indicated when the motor hum
reaches a steady pitch), turn the handle to ‘delta’ position, still
ensure to keep the push button pressed. After switching to delta,
the push button and the switch handle can be released. To stop
the motor, bring the handle of the switch to ‘O’ position. If the
starter trips automatically due to any fault, the switch handle is
first to be brought to ‘O’ position and the bimetal relay has to be
reset.
B2.
Semi automatic Star-Delta Starter (3TS02)
In this starter, the changeover from ‘star’ to ‘delta’ is done
manually by pressing ON push button.
Thus by star delta starting, the starting current is reduced to 2 to
2.5 times the rated current unlike DOL starting, where it is 7 to 8
times of the rated current.
Advantages: low starting current
Current/rated op. current
Disadvantages: Low / medium starting torque, longer starting
time, less simpler construction and wiring, requires more space
etc.

ID = Current in Δ connection

B1.
Handle Operated Star Delta Starter (3LW42)
Construction:
It consists of three contactors (3TW03), bimetal overload relay
(3UW50), and push buttons (ON-OFF, Reset) for control
command.
Operation:
To start the motor, ON’ push button is pressed and the same is
hold for 6 to 8 sec (starting time of the motor). After 6-8 sec, it is
left. After this, motor automatically changes over from star to
delta. The OFF push button has been provided to switch off the
entire circuit.
66
B3.
Fully automatic Star-Delta Starter (3TE02)
In this starter, the changeover from ‘star’ to ‘delta’ is done
automatically after a preset time by using a timer.
C. Industrial Starter:
C1.
DOL (3TW04):
This starter is similar to RAJA DOL starter with sheet steel housing
(3TW42901A). In order to offer flexibility of selecting exact 3UA
relay range by the customer, this starter has only provision for
mounting the bi-relay but the birelay is not provided in the starter.
Customer is required to select the suitable bi-relay and mount it in
the starter before putting it in service.
Construction:
It consists of three contactors (3TW03), bimetal overload relay
(3UW50), electronic timer (3RP) for automatic changeover from
‘star’ to ‘delta’ and push buttons (ON-OFF, Reset) for control
command.
C2.
Star Delta (3TE04):
Operation:
To start the motor, ON’ push button is pressed, the line contactor
and the star contactor switch-on connecting motor windings in
star formation on reduced voltage. After the preset time, the
timer automatically switches off the ‘star’ contactor and switches
‘ON’ the ‘delta’ contactor, thus after the starting period, the motor
runs on full voltage. The OFF push button has been provided to
switch off the entire circuit.
B4.
Fully automatic star delta starter in open execution
This starter is exactly same as fully automatic starter in sheet steel
housing expect the enclosure and push buttons. The contactor
and birelays are wired and mounted on the plate.
This starter is similar to star delta starter with sheet steel housing
(3TE02). In order to offer flexibility of selecting exact 3UA relay
range by the customer, this starter has only provision for
mounting the bi-relay but the birelay is not provided in the starter.
Customer is required to select the suitable bi-relay and mount it in
the starter before putting it in service.

Fuse protected selection type 2, lq = 50kA, IS/IEC: 60947-4-1
• The selection is valid only for complete Siemens combinations i.e. SDF + DIN Fuse + Contactor + Birelay (+ timer).
• In case this combination is changed to accommodate another brand/rating of SDF/DIN Fuse/Contactor/BMR, it shall be the responsibility of
the person making such a change to assure type 2 performance.
• Selection is for normal starting conditions with starting time ≤ 6 seconds. For heavy starting applications (e.g. ID/FD fans, reciprocating
compressors, ball mills etc.), please consult Siemens.
• At 60°C service temperature the bi-relay has to be derated. The bi-relay can be used upto the maximum current setting indicated. For example - A
bi-relay with setting 32-50A, at 60°C can be used only upto 47A. This however does not mean that at 60°C, the 50A setting corresponds to 47A. It
means that, the bi-relay should not be set beyond 47A.
• The electronic star-delta timer type 3RP should be used in star-delta feeders.
• SDF: Switch Disconnector Fuse. All fuses are DIN HRC type.
• Tested Type 2 combinations

Fuseless selection type 2, Iq = 50kA, IS/IEC: 60947-4-1
• The selection is valid only for complete Siemens combinations i.e. MPCB / MCCB + contactor + bi-relay (+timer).
• In case this combination is changed to accommodate another brand/rating of MPCB/MCCB/contactor/BMR, it shall be the responsibility of the
person making such a change to assure Type 2 performance.
• Selection is for normal starting conditions with starting time ≤ 6 seconds. For heavy starting applications (e.g. ID/FD fans, reciprocating
compressors, ball mills etc.), please consult Siemens.
• The electronic star-delta timer type 3RP should be used in star-delta feeders.
• Truly tested Type 2 combinations at neutral authorities.
• Low LCC = Low life cycle cost
