Overview

The rated current of the Dada DAM3-400 molded case circuit breaker can reach up to 400A. These electrical devices are suitable for the protection of power distribution circuits with an alternating current of 50-60Hz and a rated operating current to 1000A. They can also be used in electric motors for infrequent starting and overload protection as well as protection against short circuiting and undervoltage conditions.
Compared to the DAM1 series, the DAM3 series are designed for smaller volume, higher breaking capacity, offering better energy savings.
