There is a saying that "every bit helps" and now with the industries smallest* general purpose Magnetic Contactor
in its class, customers are able to more easily down-size their boards than ever before.
The perennial issues of remembering to order the terminal covers, fitting them correctly or loosing them in the
process are challenges of the past. The integrated terminal cover system means they are always there, on the
Magnetic Contactor or its Auxiliary contact, ready to be used.
*based on a survey of 10A frame class Magnetic Contactors conducted for Mitsubishi Electric September 2012

Reduction

Traditional solution: Cover + Contactor
Reduce your coil inventory by up to 50%
36mm × 5 units = 180mm
The new ST series has new wide range operating coils which mean 50% fewer variations are required to span the 24-550V voltage
range compared to the previous SN series. This means a smaller stock burden for those users who hold main stock or spare parts.

Your confidence: Certified
Smart Wiring
Many customers are engaged in business which can mean them exporting to countries around the world and
therefore having to comply with those local standards. The MS-T Series is certified to the highest international levels
while work is ongoing to gain other country and shipping standards to help put your "mind at rest".
International
Standards
Smart design means Smart wiring
The integrated terminal covers have an additional benefit in that they act as a guide to improve wiring efficiency
but also retain the terminal screw in place: no mislaying the screw, no dropping it or having trouble reinserting it
in to the terminal block just fast efficient wiring. Fast wiring terminals (model name with suffix “BC” ) are also
available to further improve wiring efficiency, workability and hence productivity.

Main circuit specifications
The minimum working voltage and current of the main and auxiliary contacts of the S-T type Magnetic Contactors and the contact
of the SR-T type Contactor Relays vary depending on the allowable failure rate. Apply the following diagrams.
■The contact reliability reduces when a contact is connected in series or when the current is applied and broken at
the time of opening and closing the contact.
Prescribe remedies such as connecting the contact in parallel (providing redundancy).
■The contact must be connected in parallel (providing redundancy) if reliability greater than the contact reliability
shown the diagrams 1 to 3 is required.

Note 1: The contact reliability indicates the failure rate λ60 (the number of failures/the number of opening and closing operations, per contact) at 60% reliability standard.
This reliability is applied when the product is in use under a clean atmosphere in the standard specification environment (Refer to page 44).
Note 2: The contact resistance of the contacts may change due to economical corrosion and that may affect the contacts in the case of a light load.
It is recommended that regular inspections to be conducted, with load opening and closing performed several times in the inspection, and that consideration be provided on the
system side.

The TH-T type adjusts the minimum operating current with the standard electric wire size shown in the following table. If the electric wire is
thicker or thinner than this standard electric wire size, the operating current becomes high or low, respectively. Therefore, correct the
stabilized current (divide it by the change rate of the minimum operating current) to use a size different from the standard connecting
electric wire size.

Compensation factor: Percentage of the minimum operating current at the ambient temperature of 20°C
(the temperature on the control board of 35°C)
<Compensation procedure of setting current>
Determine the compensation factor of the working ambient temperature according to the curves in diagrams 1 and 2 and use the value of all load currents of the motor divided by
the determined compensation factor as the stabilization value.
Example: The ambient temperature compensation factor for TH-T25 at the ambient temperature of 40°C (the temperature on the control board of 55°C) is 97% at the minimum
scale according to diagram 2. If the motor rated current is 15A, the stabilization value is 15.5A (=15/0.97). )
Note 1: [*1] The ambient temperature applied to the MS type indicates the outside temperature of the box. To be released in the future
[*2] The temperature including temperature increase on the control board applied to the MSO type is indicated.

Operating time
The TH-T type Thermal Overload Relays are adjusted with the Magnetic Starters in the standard box (the MS type) relative to the ambient temperature of
20°C (The temperature on the control board of the MSO type Magnetic Starters is 35°C). The ambient temperature compensator is mounted on the TH-T
type Thermal Overload Relays. Therefore, the ambient temperature less affects the operational characteristic change. The minimum operating current
change according to the ambient temperature change relative to the ambient temperature of 20°C (the temperature on the control board of 35°C)
generally depends on the characteristics in the diagrams 1 and 2.
The Thermal Overload Relays have a characteristic that the operating current becomes high when the ambient temperature is low and becomes low when
the ambient temperature is high. If the ambient temperature of the installation site is significantly different from 20°C (the temperature on the control board
of 35°C), the setting current of the Thermal Overload Relays needs to be corrected as shown in diagrams 1 and 2. In addition, note that the compensation
factor has a characteristic to be the minimum scale>middle scale>maximum scale at the adjustment knob location. (Note that the Thermal Overload
Relays may operate at a current of less than 100% stabilized current if in use at temperatures exceeding the allowable working temperature of 40°C (55°C).)

●Tightening torque of mounting screw
●Performance
The performance described in this catalog is based on the result of a test conducted under the conditions specified in the Standard (IEC60947-4-1 "Low-voltage
switchgear and controller" etc.). If actual use condition is different from this test condition, the user must evaluate the condition (by using an actual device).
1.2 to 1.9
●Mounting of IEC 35mm wide rail
(1) T10 to T32 types and SR-T type are standard devices allowed to be mounted
on an IEC 35mm wide rail.
(2) DIN, EN, IEC, and JIS C2812 standards-compliant 35mm wide rails come in
two types: 7.5mm and 15mm in rail height. Their shapes and dimensions are
as shown in the figure below.
●Use condition

Mounting
●Direct mounting
(1) The device should be mounted in a dry location low in dust and vibration.
(2) The normal mounting direction is the direction shown in Fig. 1 on a vertical surface, but mounting the device at an inclination angle of up to 30 degrees in either direction is allowed. (Fig. 2)
(3) Mounting the device on a floor or ceiling is not allowed. (Mounting the device on a floor or ceiling may affect the continuity performance, operation performance, and durability of the contact.)
(4) If mounting the device in a horizontal orientation cannot be avoided, be sure to rotate the device by 90 degrees in a counterclockwise direction from the normal mounting direction as shown in figure 3 when mounting it.
If the device is mounted in a horizontal orientation, its characteristic is nearly unchanged but mechanical durability may be deteriorated. Horizontal mounting of reversing type is not allowed.

When mounting a rail on a surface of the board, be sure to
keep the rail mounting screw pitch below the dimension shown
in the following table in order to secure sufficient mechanical
strength.

●Mounting space and arc space
When mounting the Magnetic Contactors side by side, be sure to keep the devices isolated by a distance longer than the dimension
shown in the following table. Also, the Magnetic Contactors and adjacent grounding metal should be isolated by a distance longer than the
dimension shown in the following table. The content described in ( ) is applied when additionally mounting auxiliary contacts.
Although an arc space is not required in a position above the Magnetic Contactors, it is recommended to provide a space longer than the
E dimension shown in the following table in consideration of the product movement caused by variation in depth dimension of Magnetic
Contactors and the vibration produced when turning on or releasing the contactor.

Although the device can operate without any problem when under the conditions described in this chapter, be careful about the following
matters.
(1) Ambient temperature
Even when the device is used in accordance with normal usage, deterioration of the insulation will progress.
In particular, as the ambient temperature increases, the insulation life is shortened. In general, it is said that every time the ambient
temperature increases by 6 to 10°C, the insulation life decreases by half (Arrhenius law). In a case where the ambient temperature is high and
voltage exceeding the rated voltage is continuously applied to coil, the coil temperature increases and life may be shortened dramatically.
(2) Vibration/Impact
Although vibration of 19.6m/s2 and impact of 49m/s2 do not cause contact malfunction, even when the vibration and impact are below these
values but are applied continuously, fatigue failure may cause some trouble.
In particular, please note that the resonance of an installed board may exert a large vibration on the product.

When using Magnetic Starters or Magnetic Contactors at high ambient temperature, the temperature may mainly affect the insulation life (continuous
electric conduction life) of the operation coil and the aging variation of the molding component.
MSO and S-T type without a box are standard products available even at the inside temperature of 55°C.
●Low temperature
Although the Magnetic Contactors may be transported to a cold region or used in such a cold region or under cold conditions such as those found in
a refrigerator with the contactor incorporated in a switchboard, the S-T type Magnetic Contactors is applicable as a standard product. Also, MSO-T
type Magnetic Starters and TH-T type Thermal Overload Relays of low temperature specification are not manufactured.
Applicable temperature range of low-temperature-based products: -50 to 55°C (Operating temperature)
-60 to 65°C (Storage temperature)
●Corrosive gas
●Application to a circuit exceeding 380V
(1) When applying MSO, S-T10, T12, T20, SR-T5, T9, and TH-T18 types to

dimension, so please avoid the mixed use of such screws. This may break the insulation barrier or make the wire likely to fall out.
Note 4: When using IEC60529-based finger safe specification, be sure to use an insulation tube-attached crimp lug.
Note 5: Tightening the3 terminal screw excessively without wiring may break the screw and consequently disable the tightening, so please avoid
such excessive tightening.
Note 6: Operational circuits are coil terminals of magnetic contactors and control circuit terminals of Thermal Overload Relays.
Note 7: Please use swaging tool which is recommended by JST.
(1) Operating voltage
When the rated voltage and frequency are applied to the coil at an ambient temperature of 40°C (Inside temperature of the board: 55°C),
the device operates without any problem at 85 to 110% of the rated voltage of the coil after the temperature increases and becomes
saturated.
(2) Voltage drop
Even when the coil is excited at the rated voltage and the voltage drops to 65% of the rated voltage (first 1 to 2 cycles; however in
case of 0.1 second or more, 70%) when the main contact is contacted, contact welding does not occur at a current ten times the rated
operational current, allowing the device to operate without any problem.
(3) Voltage/Frequency and coil rating of operating circuit
The voltage/frequency of the operating circuit and the same of the operation coil must be matched.
Applying a voltage exceeding 100% of the rated voltage to the operating circuit when using the coil may acceleratedly deteriorate the coil insulation
and consequently reduce mechanical durability, so set the coil's average voltage to 95 to 100% of the rated voltage when using the coil.
Please note that the operating characteristics of the magnetic contactor and thermal overload relay may vary with the ambient temperature.

S-T type Magnetic Contactors is of corrosion resistance-increased specification as a standard product.
Corrosive gases that exist in an environment with an Magnetic Starters or Magnetic Contactors used are gases such as sulfurous acid
(SO2), hydrogen sulfide (H2S), chlorine (Cl2), and ammonia (NH3), and conductive portions can be protected by plating a metal resistant
to such gases on the portion. However, because there is no adequate corrosion prevention method for the contact, such gases may
increase the contact resistance, resulted in increased temperature.
Additionally, if the environment contains some corrosive gas but is under dry condition, this may delay the progression of corrosion, so
using the switchboard with the inside kept as dry as possible is also one of the corrosion prevention methods.
In the Magnetic Starters and Thermal Overload Relays, corrosion-prevented products (MSO-T□YS, TH-T□YS) of the specification
with increased corrosion resistance to such corrosive gases are also manufactured.
●Dust
MCR
THR
In case of Reversing type circuit exceeding 500V
Magnetic Starters and Magnetic Contactors used in an iron foundry, construction site, or powder conveying machine tend to be
subject to a relatively large amount of dust. When using the control board in such locations, the board must be dust-preventionstructured. Also, using the board under hermetically-sealed condition for a long period may cause contact failure.
●Export of the products to tropical regions
The environment of exported products which pass through tropical regions tends to be of high temperature and high humidity, and
humidity is the environmental factor that affects the Magnetic Starters and Magnetic Contactors most severely. Humidity is the biggest
rust-generating factor and the exported products must be in a structure resistant to humidity.
Therefore, it is recommended to put a moisture absorbent (Silica gel) in an amount of 3kg or more per m³; so as to lower the humidity.

Product Introduction
The main circuit terminals of T10 to T32 and TH-T18/T25 types are allowed to be connected via any of single wire, stranded wire, and crimp lug. The main circuit terminals and
operating circuit terminals of T10 to T32 and TH-T18/T25 types are self-up terminals, which facilitate wiring.
If the operating circuit wiring is too long, when the coil's instantaneous current flows, the wiring impedance may cause a reduction in the coil voltage, so that the operating
circuit may fail to be activated. And, the stray capacitance of the wired line may cause the coil's excitation not to be released even when releasing the excitation.
Overseas Standard
This may cause overheating or fire. Be sure to properly keep the tightening torque and periodically re-tighten the screw.
However, please note that tightening the screw under the status where oil is adhered to the terminal portion may damage the terminal screw even within the existing tightening torque.
Electric wires should be properly connected according to the electric wiring diagram. Tightening the terminal screw should be properly conducted within the tightening torque shown in
the right table. Insufficient tightening of the terminal screw may cause overheating or cause the electric wire to drop off. Excessive tightening torque may damage the tightening screw.
Adhesion of rock paint, thermo label, etc. to electric wire connection or contact may cause heat generation due to defective continuity, so this is very dangerous.
Applying a low voltage that does not operate the Magnetic Contactors to the operating circuit may cause overcurrent to the coil, which may cause the coil to be burned in a short time.

●Make sure to disconnect the power before you perform installation, removal, wiring works, or maintenance/checking. There
is a risk of receiving an electric shock or occurrence of a malfunction.
●When the product is energized, avoid touching or coming near the product, especially the terminals having electricity. There
is a risk of receiving an electric shock or burn injury.
Notes
●Use the product in the use environment described in this catalog and Instruction Manual. Do not install the product in any
abnormal environment with high temperature, high humidity, dust, corrosive gas or excessive vibration/shock. There is a risk
of catching fire, malfunctions, electric shock or failure.
●Avoid applying shocks by dropping or falling the product during transportation and unpacking. This will lead to breakage or
failure of products.
●Do not use the product when it has received damage during transportation, installation or wiring. This can cause fire or
malfunctions.
●Make sure that only technicians qualified for electric work or wiring should perform installation, wiring works and
maintenance/checking of the product.
●Make sure that no foreign objects such as dust, iron powder and wire chips enter the product during installation and wiring
works. There is a risk of contact failures and malfunctions leading to damage or fire at the load.
●When you use mounting screws of the wrong size or use a small number of screws than specified, or when the mounting to
the rail of IEC 35mm width is defective, there is a risk that the product may fall.
●When you apply wiring works, be sure to use the wire size that suits the applied voltage, flow current and inrush current,
and to fasten wires with the correct torque as specified in this catalog or the instruction manual. Defective wiring can cause
fires, accidents and failures.
●To terminal screws and mounting screws, apply the torque as we specify for tightening, and regularly apply retorquing.
When the tightening torque is too large, the work can damage terminal screws or mounting screws. When the terminal
screws or mounting screws slacken or are broken, they can cause overheat or fire, or the body can fall off to create serious
accidents.
●Confirm the rated values and specifications, and make sure to use a product that meets the requirements. When you use a
product exceeding the rated/specified values, it may cause insulation breakdown leading to earth fault or short circuit
accidents, or create the cause of fire by overheat or breakdown due to inability to shutdown.
●When a product described in this catalog is to be used in a facility where a failure can lead to injury to the human body or
serious damage to earnings, make sure to install some safety mechanism.
●Apply regular checks to the product and use safety measures on the sequence to the critical circuits. The contacts of
Contactors and Magnetic Starters can develop defective conduction, weldingor burnout.
●Contactors and Magnetic Starters can create welding of contacts disabling the opening, due to such causes as switching
operation for excessive current, abnormal wearing of contacts, chattering at operational instruction contacts, aging
degradation and product life. Also the contacts may fail to open due to unexpected mechanical constraints other than
contact adhesion. Since the disability of contact to open can cause the machine to go out of control, secure safety by
assuming the mechanical constraints or contact welding leading to inability of open/close operations. There remains a risk
of fire even when an overload protective device (Thermal Overload Relays) is provided.
●The example connection described in this catalog only shows a typical one to run a system. For the protection of each
device and safety measures, the customer is requested to consider the connection for each system.
●Do not apply reworks to the product or disassemble the product. These may cause failures.
●When you dispose of the products, treat them as industrial waste products.
