Product Introduction
The DAM3-1600 molded case circuit breaker is designed to provide automatic current interruption whenever the current exceeds the preset release settings. The term 'molded case' refers to the durable plastic insulator that forms the frame of the device, ensuring effective insulation of the conductor and the metal grounding components.

Principles of Operation
The primary contact of the DAM3-1600 molded case circuit breaker can be closed either manually or electrically. Once closed, the free release mechanism securely locks the main contact in the closed position. The overcurrent trip coil and the thermal trip element are connected in series with the main circuit, while the undervoltage trip coil is connected in parallel with the power supply, ensuring comprehensive protection and control.
