Overview
The Dada DAM3-1600 molded case circuit breaker boasts a robust rated current capacity of up to 1600A. These advanced electrical devices are ideal for safeguarding power distribution circuits operating at an alternating current of 50-60Hz with a rated operating current up to 1000A. Additionally, they are perfectly suited for electric motors, offering reliable protection during infrequent starting, guarding against overloads, short circuits, and undervoltage conditions.
The DAM3 series surpasses the DAM1 series in design and efficiency, featuring a more compact form factor, superior breaking capacity, and enhanced energy savings.

Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically interrupt the current flow when it exceeds pre-set limits. The term 'molded case' refers to the durable plastic insulator that encases the device, providing excellent insulation for the conductor and metal grounding components.
Working Principle
The main contact of the DAM3-1600 molded case circuit breaker can be manually operated or electrically closed. Once the main contact is engaged, the free release mechanism secures it in the closed position. The overcurrent trip coil and thermal trip element are series-connected within the main circuit, while the undervoltage trip coil is connected in parallel with the power supply.
