2P 4P MCB Circuit Breaker 63 Amp With Shunt Release 230V

Product Specification

63A Miniature Circuit Breaker With Shunt Release MCB Circuit Breaker

Application

ZMB-1S-63 miniature circuit breaker with shunt release(special switch for card type meter) has function ofshunt tripping, is suitable for circuitries of AC50Hz or60Hz, rated working voltage is 230/400V and ratedcurrent up to 63A, it carries out far-span controlbreaking or automatic signal control breaking to thecircuitries, while protects the circuitries against overloador short-circuit, it also can be used for infrequentchangeover for circuitries. At present, the productsare widely matched with IC card prepayment watthourmeters and used to control the making and breakingof circuitries, are ideal supporting products for ICcard prepayment watthour meters. The products are in conformity with GB10963.1-2005,with international advanced level.

Function characterstic

The circuit breaker has an over-current protection pole and an opening and closingneutral pole, as well as shunt tripping device.Opening and closing neutral pole will make first and break later than the over-currentprotection pole; High rated breaking capacity, as high as 6kA; Operating mechanism of the circuit breaker is a free trip mechanism with energystorage function, the contact can close quickly, it overcomes the adverse effectcaused by the handle speed variation of manual operation, improves the product'sservice life greatly; during normal working, the contact can only rest on closing orbreaking position; Combined type contact terminal with finger touch protection, high safety; Drive element of shunt release is composed of thyristor, electromagnetic releaseand so on; Both the shell and components are made of imported high flame retardant, hightemperature resistant and impact resistant plastics.

Working principle

When using, apply control voltage to the intelligent shunt release pole of circuit breaker through signal input port, i.e. signal voltage (can be provided by remote control circuit), then push the circuit breaker handle towards closing position, drive the moving contact to run towards static contact and reliably contacting with it throughoperating mechanism, and put through the circuit. When the circuit has overload fault,overload current would bend the bimetallic element, overload release acts and pushesthe locking mechanism to reset, to break the circuit. When the circuit has short-circuitfault, short-circuit current would make the instantaneous release act, which pushes the locking mechanism to reset, to break the circuit. When the circuit must be cut offimmediately for some reason, the control voltage may be cut off by wireless controlsystem, at this moment, the signal voltage detection circuit receives the signal, andoutputs voltage signal to the shunt coil, it drives the whole shunt coil to act, andpushes the locking mechanism to reset, to realize breaking function. Therefore, thisproduct is able to realize breaking under different circuit states.
