Introduction
The DAM3-1600 molded case circuit breaker is engineered to automatically interrupt the current flow when it surpasses the pre-set release threshold. The term 'molded case' signifies the use of a robust plastic insulator that forms the frame of the device, ensuring effective insulation of the conductor and the metal grounding components.
Working Principle
The operation of the DAM3-1600 molded case circuit breaker is either through manual manipulation or electric closing of the main contact. Once the main contact is secured in the closed position by the free release mechanism, overcurrent trip coils and thermal trip elements connected in series with the main circuit, along with undervoltage trip coils connected in parallel with the power supply, ensure reliable protection.
