Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
The Dada DAM3-1600 Molded Case Circuit Breaker is an outstanding electrical solution with a robust rated current capacity reaching up to 1600A. These versatile devices are expertly engineered to protect power distribution circuits operating with an alternating current frequency of 50-60Hz and a rated current of up to 1000A. In addition to safeguarding power distribution, they are adeptly designed for use in electric motors where they provide reliable protection during infrequent starting, guarding against overloads, as well as offering comprehensive protection against short-circuiting and undervoltage scenarios.

In a class of its own, the DAM3 series represents a significant advancement over the DAM1 series with its compact design and enhanced breaking capacity. This series not only offers superior energy efficiency but also optimizes performance with reduced size and weight.

Introduction
The DAM3-1600 molded case circuit breaker is a remarkable device that automatically interrupts the current when it surpasses the pre-set release threshold. The term 'molded case' refers to the use of a high-grade plastic insulator that forms the device's frame, ensuring thorough insulation of the conductor and safeguarding the metal grounding component.

Working principle
The operational dynamics of the DAM3-1600 molded case circuit breaker involve either manual or electric closing of the main contact. Once closed, the sophisticated free release mechanism ensures the main contact remains securely in the closed position. The integral overcurrent trip coil and thermal trip element are meticulously connected in series with the main circuit, while the undervoltage trip coil maintains a parallel connection with the power supply, ensuring reliable and efficient operation.
