Overview
The Dada DAM3-1600 Molded Case Circuit Breaker is engineered to deliver superior performance with a rated current capability of up to 1600A. Ideal for safeguarding power distribution circuits operating on alternating current within the 50-60Hz range and a rated operational current up to 1000A. Additionally, these devices are well-equipped for electric motor applications, featuring capabilities for infrequent starting, overload protection, and defense against short circuits and undervoltage scenarios.
In comparison to the DAM1 series, the DAM3 series stands out with its more compact design, higher breaking capacity, and enhanced energy efficiency.

Introduction
The DAM3-1600 Molded Case Circuit Breaker is designed to automatically disconnect the current when it exceeds the preset release setting, ensuring optimal safety and protection. The term 'molded case' refers to the robust plastic insulator that serves as the frame, effectively insulating the conductor and the metallic grounding component.
Working Principle
The operation of the DAM3-1600 Molded Case Circuit Breaker involves manual or electric closing of the main contact. Upon closure, the free release mechanism secures the main contact in its closed position. The device incorporates an overcurrent trip coil and a thermal trip element connected in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply.
