Overview
The rated current of DAM3-1000 molded case circuit breaker can up to 690A, it’s generally used in the power distribution circuit to distribute power and protect circuit and power equipment from overloaded, short circuit, under voltage failure damage, in which alternating current 50-60Hz, rated direct-current 1000A.
Compared to the DAM1 series, the DAM3 series are designed for smaller volume, higher breaking capacity, offering better energy savings.
