Product Description

DAM3-1600 MCCB Molded Case Circuit Breaker

Overview
The Dada DAM3-1600 Molded Case Circuit Breaker boasts a robust rated current capacity of up to 1600A. Engineered for excellence, these devices are ideal for safeguarding power distribution circuits with an alternating current range of 50-60Hz and a rated operating current up to 1000A. Additionally, they serve as reliable protectors for electric motors, handling infrequent starts, overload protection, and safeguarding against short circuits and undervoltage conditions.

The DAM3 series stands out from its predecessor, the DAM1 series, by offering a more compact design, superior breaking capacity, and enhanced energy efficiency.

Introduction
The DAM3-1600 Molded Case Circuit Breaker is engineered to automatically disconnect the current when it surpasses the release setting. The term 'molded case' pertains to the plastic insulator framing the device, ensuring effective insulation of the conductor and the metal grounding component.

Working Principle
The DAM3-1600 Molded Case Circuit Breaker's main contact can be engaged either manually or electrically. Once closed, the free release mechanism secures the main contact in its closed state. The overcurrent trip coil and thermal trip element are integrated in series with the main circuit, while the undervoltage trip coil is parallel to the power supply, ensuring comprehensive protection.
