Product Description

Overview
Dam3-400 MCCB Compact Economical Type Moulded Case Circuit Breaker Factory Price CB Approved for Switchgear Application



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 1600A. 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.

Introduction
The DAM3-400 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.
