Scope of Application

DZ47S-125 Miniature Circuit Breaker (known as shunt trip MCB, 100 amp Circuit Breaker shunt trip). The shunt trip MCBis suitable for the control line of AC 50Hz or 60Hz, rated voltage 230V/400V, rated current of 125A and below, remote control and automatic signal breaking control for the line, is mainly used for over-load and short-circuit protection in circuits. And infrequent transfer between circuits in normal condition. Currently the shunt trip MCB is widely used in single-phase/ three-phase intelligent prepaid energy meter (such as IC card) to achieve the on-off of control lines. The series of products have high breaking capacity, small size, light weight, parts versatility, beautiful appearance, etc., it is mounted on the rail and easy to use.
DZ47S-125 shunt trip MCB comply with standards of GB10963.1, IEC60898-1.
