Scope of Application

DZ47GQ-63 Voltage Protector (under voltage protection circuit breaker and over voltage protection circuit breaker) is the derivative product of DZ47-63 miniature circuit breaker With voltage module. It' s appropriate for the rated current of 1-63A, AC 50Hz, rated voltage of 230V, over-voltage protection setting value at (275 ± 5%), under-voltage protection rating of 170 ± 5%, it is used for over-current, short-circuit and over-under voltage protection of building circuit facilities and AC distribution system and electrical equipment. It is the best products installed in the residential, hotel hospitals, shops and office buildings.

Model and meaning

Structural features

◆ The Voltage Protector (under voltage protection circuit breaker and over voltage protection circuit breaker) is composed of a shell, an operating mechanism, a thermal release, an electromagnetic trip unit contact system, an arc extinguishing system and a over-undervoltage protection circuit board. The circuit breaker has overload and short circuit protection functions and is unique in design.
◆ The Voltage Protector (under voltage protection circuit breaker and over voltage protection circuit breaker) has a rated short-circuit breaking capacity of 4500A, mechanical life of more than 20,000 times, beautiful appearance. Installation guide is the TH35-7.5 type standard mounting rails.
◆ The under voltage protection circuit breaker and over voltage protection circuit breaker have the following characteristics: Safe and comfortable Handlen, over-undervoltag protection value can be set according to user requirements, wiring must pay attention to zero and firing line; power is over-entering and down-out,in line with the power line characteristics, easy to install.
