Overview
The rated current of the DaDa DAM3-1600 molded case circuit breaker can reach an impressive 1600A. These advanced electrical devices are ideal for protecting power distribution circuits operating with an alternating current of 50-60Hz, handling a rated operating current up to 1000A. Furthermore, they are perfectly suited for electric motors, providing infrequent starting, overload protection, and safeguarding against short circuits and undervoltage conditions.
Compared to the DAM1 series, the DAM3 series showcases a more compact design, significantly higher breaking capacity, and enhanced energy efficiency, making them the superior choice for modern electrical systems.

Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically disconnect the current when it surpasses the preset release threshold. The 'molded case' terminology pertains to the robust plastic insulator that frames the device, effectively insulating the conductor and the metal grounding component.
Working principle
The main contact of the DAM3-1600 molded case circuit breaker can be engaged manually or electrically. Once the main contact is secured, the free release mechanism ensures it remains in the closed position. The overcurrent trip coil and the thermal trip element are wired in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply.
