Description
BW1 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 ranging from 200 A to 6300 A. It is applied for electric power distribution and protects circuits and power equipment against faults including overload, undervoltage, short circuit and single-phase earth fault.
The circuit breaker adopts intelligent protection functions with accurate selective protection, which improves power supply reliability and prevents unnecessary power outages. It is fitted with an open communication interface to realize four-remote functions, meeting the demands of control centers and automation systems. When configured without an intelligent controller and sensors, this circuit breaker can be used as an isolator.
