Product Description

Overview

The DAM3-1000 Molded Case Circuit Breaker, with a robust rated current capacity of up to 1000A, is an essential component in power distribution networks. It expertly manages power distribution while safeguarding circuits and equipment against overload, short circuits, and under-voltage conditions. This breaker is designed for alternating current systems operating at 50-60Hz and can handle a direct current of up to 1000A.

The DAM3 series, an advanced iteration of the DAM1 series, is engineered for compactness and superior breaking capacity. These enhancements not only ensure higher reliability but also contribute to significant energy savings.

Introduction
The DAM3-1000 Molded Case Circuit Breaker is designed to automatically interrupt the current flow when it exceeds the predetermined release setting. The 'molded case' terminology refers to the durable plastic insulator that encases the device, providing essential insulation between conductive components and grounding elements.
