Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
The Dada DAM3-1600 Molded Case Circuit Breaker boasts an impressive rated current capacity of up to 1600A. Perfectly engineered for safeguarding power distribution circuits, it operates effectively within an alternating current range of 50-60Hz and supports a rated operating current of up to 1000A. This versatile device is also adept at providing reliable protection for electric motors, accommodating infrequent starting, and defending against both overload and short circuit conditions, as well as undervoltage scenarios.

Compared to the DAM1 series, the DAM3 series is distinguished by its more compact design and superior breaking capacity. This advanced series also offers enhanced energy efficiency, making it a smarter choice for modern electrical systems.

Introduction
The DAM3-1600 molded case circuit breaker is equipped with an automatic cut-off mechanism that activates when the current surpasses the preset release threshold. The term 'molded case' indicates the use of a plastic insulator as the device's frame, ensuring effective insulation between the conductor and the metal grounding component.

Working Principle
The main contact of the DAM3-1600 molded case circuit breaker can be engaged either manually or electrically. Once the main contact is closed, the free release mechanism secures it in the closed position. The overcurrent trip coil and thermal trip element are integrated in series with the main circuit, while the undervoltage trip coil is configured in parallel with the power supply, ensuring comprehensive protection and operational reliability.
