SDCM3 series circuit breakers are suitable for low-voltage power grids with AC 50/60Hz, rated current 16-1600A, rated insulation voltage of 1000V, and rated working voltage of 690V and below.
Personal electric shock and equipment leakage protection can also be used to prevent fire hazards caused by equipment insulation damage and ground fault current generation. It adopts a double-breakpoint contact system with high breaking capacity (150kA) and long electrical life.
SDCM3 series circuit breakers adopt an intelligent over-current release composed of microprocessors, with adjustable rated current and over-current protection characteristics, which can better match the load of distribution lines or motors, and serve as overloads for equipment such as lines or motors. And short-circuit protection. Under normal circumstances, the circuit breaker can also be used for infrequent switching of lines and infrequent starting of motors. It is widely used in power grids, industrial and mining enterprises, commerce, communications, data centers and other industries.
