Function

Over-current protection

• The over-current protection is composed of phase and neutral line protection (Four pole breaker and three pole breaker with current transformer linking externally to neutral N) from over-current.

• The parameters of current and time of phase line over-current protection can be set by the company in terms of the requirements of users (can be set by customers themselves); the parameters of current and time of neutral line over-current protection will be set according to the setting of the phase line, all these mainly divided into the following two situations:

Three pole breaker with the neutral connected eaternally

• To type L25, M26, H26 intelligent controller, when ordering the goods the neutral line setting current customers should have to confirm the protecting data, it has two type of 50%In and 100%In.

• To type P25, P26 intelligent controller, the customers can setup into four types from menu:turn off, 50%In, 100%In, 200%In. When

200%In neutral line protecting (if it has a high triple frequency harmonic), the neutral line cross section should be double leg of a circuit cross section in the electrical power distribution system. But to

BT2-6300 three circuit breaker, there is no neutral line protecting.

Four pole breaker

• To type L25, M25, M26, H26 intelligent controller, the customers should have to confirm the protecting data, it has two types of 50%In and 100%In.

• To type P25, P26 intelligent controller, the customers can setup into three types from menu:turn off, 50%In, 100%In.

Overload protection

• Inverse long-time delay overload protection, and its setting current Ir1 can be adjusted.

• The delay time t1 of overload long-time delay can be adjusted.

• The long-time delay overload characteristic of the type P25, P26, the curves can be adjusted. There have common type (I2t), uncommon inverse-time type (It), high-voltage fuse concert type (I4t) can be adjusted, which can matching higher-up and lower-lever's overload protection'needs. The long-time delay overload characteristic ofthe type L25, M25, M26, H26, its running according to the common type (I2t) curves,current Ir1, time t1 can beadjusted.

Short-time short circuit protection (can be OFF)

• Inverse short-time delay short circuit protection (I2t ON), and its setting current Ir2 can be adjusted.

• Definite short-time delay short circuit protection (I2t OFF), and its setting current Ir2 can be adjusted.

• The delay time t2 of short circuit short-time delay can be adjusted.

Instantaneous short circuit protection

• The setting current Ir3 of instantaneous short circuit (can be OFF) can be adjusted.

Load monitoring function

• To monitor the down stream load so as to ensure power supply of main system

• There are two patterns of load monitoring from which users t can choose one. The setting value of load-monitoring current are I

LC1

and I

LC2

, normally I

LC1

is larger than or equal to I

• Inverse characteristic of load-monitoring is the same of

after this circuit is broken off, the signal will be sent out again after time duration of t supply of this circuit is restored.

• Contact wearing indication (for M25, M26, H26, P25 and P26)

The intelligent controller has the function of contact wearing indication. Accordingly, the percentage of the equivalent to wearing times of main contact to electrical life-span times of the circuit breaker can be indicated by pushing the button of

"wearing indication".

• Self-diagnosis function (for M25, M26, H26, P25 and P26)

When the microprocessor of the intelligent controller breaks down or the ambient temperature of the microprocessor rises over 80°C±5, alarm signals can be sent out immediately.

• MCR function

When the circuit breaker is on or the controller is initially electrified, the circuit breaker would trip instantly if short-time short circuit fault occurred.

• Fault-memory function (for M25, M26, H26, P25 and P26)

The types and phases of fault, value of faulty current and breaking time would be indicated on the intelligent controller if the circuit breaker broke off as a result of faults.

• Current disequilibrium display (selective function for P25 and P26)

The intelligent controller can sent out and display, when the three phases current disequilibrium level reached the setting value (20%-80%).

Note: the three phases current disequilibrium=

(THDu, thdu).

Note: 21,22,23,24 serve as the wiring teminals of secondary circuit.

When pieces of circuit breakers are linked together up and down, zone selective interlock (ZSI) can ensure fully-selective protection of circuit breakers at higher or lower level so as to reduce the range of action by fault and the breaking time of circuit breakers. This function serves for short-time delay short circuit (I

2 t OFF) and ground-fault protection of circuit breakers.

As the sketch shown above, control lines can interlock with pieces of circuit breakers.

After detecting the fault, the intelligent controller (zone 2) will send out a signal to circuit breakers (zone1) at higher level and check whether the signal of circuit breakers (zone 3) at lower level arrives. If circuit breakers at lower level send out a signal, the circuit breaker will be on at the time duration of release delay; if circuit breakers at lower level don't send out a signal, the circuit breaker will break off instantly no matter whether the release has the protection of delay.

Note: The end 23 and 24 should be shortcircuited.

Communication

Communicative

To achieve the function of "four kinds of remote operation" at long distance by communication interface of the circuit breaker, namely, remote control, remote communication, remote adjustment and remote detection.

• Communication protocol : The application of Modbus-RTU mode

• Communication interface

• Standard interface: RS-485.

• Baud rate: 19200bps (in favour of 1200, 2400, 4800, 9600, 38400bps)

• Communication address:1-119.

• Byte format: First bit as start bit, eighth bit as data bit, second bit as stop bit, even check (in favour of non-check, odd check .)

• Network characteristic

• Twisted-pair shielded cables serve as communication lines.

• One line can link up 32 pieces of communicative circuit breakers at the same time (16 pieces of circuit breakers with components of draw-out socket communication module).

• Wiring distance is 1200m at maximum but the distance of communication can be extended by equipping with repeaters additionally.

• Real-time current, voltage fundamental current, fundamental voltage, power, power factor, electric energy, harmonic current or voltage ratio and total distortion of current or voltage.

• State data of circuit breakers such as alarm, fault, energy-storage, undervoltage, ready-for-switching-on, and the positions of switching-on and switching-off etc.

• The position of main body of the circuit breaker (components of communication module of draw-out socket for BT2 need to be purchased).

• The fetching and modification of the setting values of circuit breakers.

• Recorded data of fault last time.

• Outline data such as serial numbers and the type etc of circuit breakers.

• Long-distance operation if switching-on and switching-off.

• Circuit breakers can be switched on or off in the long-distance.

• Wiring terminals for communication.

Grounding

As the above diagram shows, a group of twisted-pair lines in the standard communication cable is employed as the communication line of 485 and the sheilding layer is grounded.

The actual practice should be possibly different such as the application of the colour of the twisted-pair line. Users could define the ways of cable's usage by themselves but the definition of the signal of each line in the cable should be made clear in advance.

▲ The under-voltage release operates in two ways: operate instantaneously and operate in time delay;

Electrical mechanism for the indication of draw-out

▲ There are four specifications of time delay for the under-voltage time delay release: 0.5s, 1s,

2s and 3s. Users should consult with the manufacturer in the light of their order about special timeand “connected” respectively, three electrical mechanisms delay specifications as from 3s and above up to 9s. The time delay accurary is ±10%;

▲ The delay module should be additionally equipped for the under-voltage delay release. The module input connects with the main circuit, and the output connects with the wiring terminals of 31 and 32 in the secondary circuit;

▲ If the voltage of power supply returns to 85% Us and above in half of the delay time, the
