DAM3-160 MCCB Molded Case Circuit Breaker
Product Description
The rated insulation voltage of the Dada DAM3-160 molded case circuit breaker can reach up to 100V. These electrical devices 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 10A to 100A. The circuit breaker plays a vital role 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 are designed for smaller volume, higher breaking capacity, offering additional energy savings.
