Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
The Dada DAM3-1600 molded case circuit breaker is engineered to handle rated currents soaring up to an impressive 1600A. These versatile electrical devices are ideally crafted to safeguard power distribution circuits operating with alternating currents of 50-60Hz, and can accommodate a rated operating current of up to 1000A. Beyond power distribution, they serve electric motors with aplomb, ensuring infrequent starting, overload protection, and reliable defense against short circuits and undervoltage conditions.

Embodying innovation, the DAM3 series distinguishes itself from the DAM1 series with its thoughtfully compact design, superior breaking capacity, and enhanced energy efficiency for modern electrical needs.

Introduction
The DAM3-1600 molded case circuit breaker is adept at autonomously interrupting the current flow when it surpasses the release setting threshold. The term 'molded case' pertains to the robust plastic insulator that forms the framework of the device, offering reliable insulation for the conductor and the metal grounding components.

Working Principle
The operational finesse of the DAM3-1600 molded case circuit breaker lies in its dual-mode main contact operation-manual manipulation or electric closing. Upon closure, the free release mechanism meticulously secures the main contact in position. Both the overcurrent trip coil and the thermal trip element are intricately linked in series with the main circuit, while the undervoltage trip coil is strategically connected in parallel with the power supply, ensuring seamless and dependable protection.
