YCM1 LE series earth leakage circuit breaker (herein after called circuit breaker)is applied for the power distribution network of AC SOHz,rated current SODA.The ci「cuit b「eake「 can protect people against indirect contact with dangerous electric cu「rent and p「event 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 moto 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 YCM1 LE complies with standard of IEC60947-2, GB14048.2.
Without cu「rent release components, N-Pole is alwaus at making status, not makes and breaks with other three poles;
Without cu「rent release components, N-Pole makes with the other three poles(NPole first makes then breaks);
With current release components, N-Pole makes and breaks with othe「three poles(N Pole first make then breaks);
With current 「elease components, N-Pole is always at making status, not makes and breaks with other th「ee poles;
