CNC YCM1LE-2P,3P,4P China Manufacture MCCB Circuit Breaker
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.
