Structure and working principle

Application example:


DZ47-63 MCB is mainly composed of insulation case, operating system, contact system, thermal magnetic system and arc extinction system and other components. Signal control release consists of the signal input port, signal voltage detection circuit, delay control circuit and the trip mechanism and so on. MCCB and the signal-controlled trip have linkages by the pushrod.

Working principle:

By the signal input port, the circuit breaker signal control release is added control voltage, witch is the signal voltage (which can be provided by the remote control circuit), and then push the breaker handle to the closed position, through the operating mechanism to make the moving contact operate to the static contact and contact with the static contact, then the line connected. When the line has overload fault, the overload current make bimetallic element bend, overload release action promotes the locking mechanism action to achieve breaking the line. When the line has short-circuit fault, the short-circuit current makes instantaneous release act, to promote the locking mechanism to achieve breaking function. When due to some need to immediately cut off the line, which can cut off control voltage by the remote control system, the signal voltage detects circuit and obtains the signal, then outputs the voltage signal to the trip coil to make the locking mechanism act and realize the breaking function. So the product in different line state can achieve the purpose of breaking.

Structural features

Circuit breaker with shunt trip device, has the following characteristics:
On-off neutral pole is faster on and slower off than the current protection pole;
High rated breaking capacity, up to 6kA;
The operating mechanism of the circuit breaker is the free tripping mechanism with energy storage. The contact is quickly closed, which overcomes the adverse effect caused by the speed of manpower operating handle, greatly improving the service life of the product. In normal work, the contact can only stay in the on or off position;
Shunt release consists of the SCR, electromagnetic release and so on;
Case and components are made of plastic of the high flame retardant, high temperature, impact resistant.

Wiring: 25mm² and below for wire connection, wiring method is screws to tighten the wiring, the torque is 2.0N · m.
