Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically sever the current when it surpasses preset thresholds. The term 'molded case' denotes the utilization of a plastic insulator as the framework, effectively isolating the conductor from the metal grounding components, ensuring safety and reliability.

Working Principle
The operation of the DAM3-1600 molded case circuit breaker involves either manual or electric closing of the main contact. Once closed, the main contact is secured in place by a free release mechanism. The overcurrent trip coil and thermal trip element are integrated in series with the main circuit, while the undervoltage trip coil and power supply are configured in parallel, ensuring comprehensive protection and efficient operation.
