Introduction
The DAM3-1600 Molded Case Circuit Breaker is engineered to automatically sever the current flow when it surpasses the release setting, ensuring safety and reliability. The term 'molded case' refers to the robust plastic insulator that forms the framework of this device, acting as a barrier to insulate the conductor and the metal grounding component, thereby enhancing operational safety.
Working principle
The operational brilliance of the DAM3-1600 Molded Case Circuit Breaker lies in its intricate mechanism. The main contact can be deftly controlled manually or electrically closed. Once the main contact achieves closure, the ingenious free release mechanism secures it firmly in the closed position. The system intricately connects the overcurrent trip coil and the thermal trip element in series with the main circuit, while the undervoltage trip coil and power supply are wired in parallel, ensuring seamless and efficient protection.
