Thermal-magnetic circuit breaker RDCM1L(CM1L) series

voltageshort-circuitAC

Application RDCM1L(CM1L) series leakage MCCB is mainly used in the circuit of AC 50/60Hz, rated working voltage up to 400V, and rated current from 16A-630A in distribution line for distributing power, protecting line, overload, short-circuit and leakage protections. It also can be used for infrequently starting of motor for overload and short-circuit protections. It is small size, high breaking capacity and short arcing and adjustable residual operating current.And it can with alarm contact, shunt release and auxiliary contacts. The products can be installed vertically and horizontally. The product meets the standards of GB14048.2 and IEC60947-2.
