LMM3L series plastic case residual current action protector (hereinafter referred to as circuit breaker) is suitable for infrequent switching in circuits with AC 50/60HZ, rated operating voltage AC 415V, and rated operating current up to 800A. The circuit breaker has overload, short circuit and under-voltage protection functions, which can protect lines and power equipment from damage. At the same time, it can also deal with potential risks such as personal safety and fire hazards caused by long-term ground faults that cannot be detected by the over-current protection function.
