YCM1LE Earth Leakage MCCB
General
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.
The YCM1LE complies with standard of IEC60947-2.

Note
Without current release components, N-Pole is alwaus at making status, not makes and breaks with other three poles;
Without current release components, N-Pole makes with the other three poles(NPole first makes then breaks);
