Overview
The rated current of the Dada DAM3-1600 molded case circuit breaker soars up to an impressive 1600A. These cutting-edge electrical devices excel in safeguarding power distribution circuits with an alternating current of 50-60Hz and a rated operating current of up to 1000A. Furthermore, they are adept at protecting electric motors during infrequent starts, providing robust overload protection, and guarding against short-circuiting and undervoltage conditions.
Compared to the DAM1 series, the revolutionary DAM3 series is crafted for a more compact form factor and higher breaking capacity, ensuring superior energy savings and enhanced performance.

Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically interrupt the current flow when it surpasses the release setting, embodying a perfect blend of safety and innovation. The term 'molded case' signifies the utilization of a plastic insulator as the device's frame to effectively insulate the conductor and the metal grounding component.
Working principle
The primary contact of the DAM3-1600 molded case circuit breaker can be engaged manually or electrically. Once closed, the free release mechanism secures the main contact in its closed position. The overcurrent trip coil and thermal trip element are intricately connected in series with the main circuit, while the undervoltage trip coil operates in parallel with the power supply, ensuring optimal performance and protection.
