Scope of Application
● The DZ47-125 series Molded Case Circuit Breakers (hereinafter referred to as the circuit breaker) are primarily suitable for providing overcurrent protection in AC 50Hz power line installations and electrical equipment with a rated voltage of 400V and a rated operational current up to 100A. They can also be used for infrequent switching operations. Special requirements may include adding a signal-controlled tripping function for remote control disconnection or automatic signal-controlled disconnection of lines. Currently, the signal-controlled tripping function is widely used in conjunction with IC card prepaid energy meters to control circuit switching.
● This circuit breaker complies with the requirements of standards such as GB14048.2 "Low-voltage switchgear and controlgear - Part 2: Circuit-breakers".
