LMW3 Series Air breaker circuit manual

The LMW3 series universal circuit breaker (hereinafter referred to as the circuit breaker) is suitable for power distribution networks with AC 50Hz, rated voltage up to 690V and below, and rated current 200A~1600A. It is used to distribute electric energy and protect lines and power equipment from overload, under-voltage, short circuit, single-phase grounding and other faults. The circuit breaker has intelligent protection function and precise selective protection, which can improve the reliability of power supply and avoid unnecessary power outages. At the same time, it has an open communication interface and can perform “four remotes” to meet the requirements of the control center and automation system.
