Product Description

Overview



The rated insulation voltage of the DAM3-160 molded case circuit breaker is 1000V. These circuit breakers are suitable for power distribution circuits with an alternating current of 50-60Hz, a rated operating voltage up to 400V, and rated operating current from 25A 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.

Introduction

The DAM3-160 molded case circuit breaker automatically cuts off the current when the current exceeds the release setting. The molded case refers to the plastic insulator used as the frame of the device to insulate the conductor and the metal grounding component.
