What is the role of the circuit breaker?
High and low voltage switchgear, to the whole product using digital transmission security monitoring, appearance modeling, performance indicators, durability to the country, and industry standards, praised by domestic and foreign customers.
when the current exceeds its rated (Suzhou) Co., Ltd. production of "Samui" brand circuit breakers, contactors, dual power switch, load disconnector, fire monitoring detectors, control and protection switches,
the circuit breaker internal trip mechanism, there is a different coefficient of expansion when the two kinds of metal bonding bimetallic together,
Circuit breaker in the line when the current can be disconnected from the power supply, the protection of the line, the principle is as follows
