Description
BW1A Series Intelligent Low-Voltage Air Circuit Breaker (hereinafter referred to as the circuit breaker) is suitable for power distribution networks with AC 50 Hz / 60 Hz, rated voltage up to 690 V and rated current from 200 A to 6300 A. It is used for electric power distribution and protects circuits and power equipment against faults such as overload, undervoltage, short circuit and single-phase earth fault.
The circuit breaker is equipped with intelligent protection functions and provides accurate selective protection, which improves power supply reliability and avoids unnecessary power outages. It also has an open communication interface to realize four-remote functions, satisfying the requirements of control centers and automation systems. When supplied without intelligent controller and sensors, this circuit breaker can be used as an isolator.
