Overview
The Dada DAM3-1600 Molded Case Circuit Breaker is engineered to handle rated currents up to 1600A. These robust devices are ideal for safeguarding power distribution circuits operating on 50-60Hz alternating current, with a rated operating current extending up to 1000A. Additionally, they serve as reliable protections for electric motors, providing infrequent starting capabilities, overload protection, and defense against short circuits and undervoltage conditions.
Compared to the DAM1 series, the DAM3 series boasts a more compact design and higher breaking capacity, delivering superior energy efficiency and savings.

Introduction
The DAM3-1600 Molded Case Circuit Breaker is designed to automatically interrupt the current when it surpasses the preset release threshold. The term 'molded case' refers to the plastic insulator that forms the device's frame, insulating the conductor from the metal grounding components.
Working Principle
The main contact of the DAM3-1600 Molded Case Circuit Breaker can be operated manually or electrically. Once the main contact is closed, a free release mechanism secures it in the closed position. The overcurrent trip coil and thermal trip element are connected in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply.
