Overview
The rated insulation voltage of the DAM3-160 molded case circuit breaker is 160V. These circuit breakers are suitable for power distribution circuits with an alternating current of 50-60Hz, a rated operating voltage up to 750V, and rated operating current from 12.5A to 160A. The circuit breaker is important in distributing power and protecting the circuit and power equipment from overloading, short circuits, and undervoltage failure damage. 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 with the DAM1 series, the DAM3 series have the characteristics of smaller volume, higher breaking capacity, and more energy saving.
