Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
Introducing the Dada DAM3-1600, a superior molded case circuit breaker engineered for excellence! With a formidable rated current capacity of up to 1600A, these devices are the perfect solution for safeguarding power distribution circuits operating on an alternating current of 50-60Hz, with a rated operating current that can reach as high as 1000A. Not just limited to circuit protection, they are also ideal for electric motors, providing infrequent starting, robust overload protection, and secure defenses against short circuiting and undervoltage scenarios.

The DAM3 series stands out with its compact form and enhanced breaking capacity, a significant upgrade from the DAM1 series, all while delivering exceptional energy efficiency and savings.

Introduction
The DAM3-1600 molded case circuit breaker is a state-of-the-art device that automatically interrupts the current flow when it exceeds the predefined release setting, ensuring safety and reliability. 'Molded case' refers to the sophisticated plastic insulator that forms the device's frame, expertly insulating the conductor and the metal grounding component, ensuring maximum protection and durability.

Working principle
The operation of the DAM3-1600 molded case circuit breaker is both manual and electric. When the main contact is activated, the innovative free release mechanism secures the main contact in the closed position seamlessly. The device's overcurrent trip coil and thermal trip element are ingeniously designed to be in series with the main circuit, while the undervoltage trip coil is adeptly connected in parallel with the power supply, showcasing an advanced approach to circuit safety.
