Audited Supplier CNC Ycm1le 2p, 3p. 4p Earth Leakage Circuit Breaker MCCB
YCM1LE series earth leakage circuit breaker (herein after called circuit breaker)is applied for the power distribution network of AC 50Hz,rated current 630A.The circuit breaker can protect people against indirect contact with dangerous electric current and prevent fire disaster caused by insulation fault and single-phase ground fault. It can be used to distribute electric power and protect power equipment against overload and short circuit. The circuit breaker can change the circuit and start motor infrequently. The rated residual operating current and the maximum off-time can be adjusted on-site according to actual situation, the circuit breaker can be customized alarm function and no tripping function.
