Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
The rated current of the DaDa DAM3-1600 molded case circuit breaker can reach an impressive 1600A. These advanced electrical devices are expertly crafted for safeguarding power distribution circuits operating with alternating currents between 50-60Hz and a rated operating current of up to 1000A. Furthermore, they are highly effective for use in electric motors, offering reliable protection for infrequent starting, overload conditions, and safeguarding against short circuits and undervoltage situations.

In comparison to the DAM1 series, the DAM3 series is engineered for a more compact form factor, significantly higher breaking capacity, and superior energy efficiency, ensuring optimal performance for modern electrical systems.

Introduction
The DAM3-1600 molded case circuit breaker is designed to automatically disconnect the current flow when it exceeds the preset release threshold. 'Molded case' refers to the robust plastic insulator that serves as the device's frame, providing essential insulation for the conductor and the metal grounding component.

Working principle
The primary contact of the DAM3-1600 molded case circuit breaker can be closed manually or electrically. Once closed, the free-release mechanism secures the main contact in the closed position. The overcurrent trip coil and the thermal trip element are intricately linked in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply, ensuring comprehensive protection.
