In-Depth Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically sever the current flow when it exceeds the pre-set release threshold. The term 'molded case' refers to the robust plastic insulator framing the device, ensuring thorough insulation of the conductor and metal grounding components.

Innovative Working Principle
The closing of the main contact of the DAM3-1600 molded case circuit breaker can be executed manually or electronically. Once closed, the free release mechanism secures the main contact in this position. The series connection of the overcurrent trip coil and thermal trip element with the main circuit, along with the parallel connection of the undervoltage trip coil and the power supply, ensures comprehensive protection and operational efficiency.
