Residual Current Operated MCCB YCM1LE timer circuit breaker

    Residual Current Operated MCCB YCM1LE  timer circuit breaker General YCM1LE series residual Current Circuit Breaker(herein after called circuit breaker)is applied for the power distribution network of AC 50Hz,rated current 800A.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, GB14048.2.     Main parts: main switch (including current release), zero-sequence transformer, electronic amplify parts, residual release.   Related products MCCB       YCM1   YCM2  YCM3  YCM6 YCM7 ELCB        YCM1LE   YCM3LE   YCM7LE   YCM9LE     Type designation   Specifications
