Introduction
The innovative DAM3-1600 molded case circuit breaker is designed to automatically interrupt the current when it surpasses the preset release setting, ensuring maximum safety and efficiency. The term 'molded case' refers to the durable plastic insulator that forms the frame of the device, effectively insulating the conductor and the metal grounding component, thereby enhancing reliability and performance.

Working Principle
The operation of the DAM3-1600 molded case circuit breaker is marked by a seamless blend of manual and electric mechanisms. Once the main contact is securely closed, the free release mechanism adeptly locks it into the closing position. The overcurrent trip coil, along with the thermal trip element, integrates seamlessly in series with the main circuit, while the undervoltage trip coil interfaces in parallel with the power supply. This sophisticated setup ensures unwavering protection and superior operational efficiency.
