Introduction
Engineered with precision, the DAM3-1600 molded case circuit breaker is designed to automatically discontinue current flow once it exceeds the predetermined release setting. The 'molded case' refers to its durable plastic insulator frame, which effectively isolates the internal conductors and metal grounding parts, ensuring utmost safety and dependability.

Working principle
The DAM3-1600's main contact can be activated manually or electrically. Upon closing, the free release mechanism securely locks it in position. The overcurrent trip coil and thermal trip element are linked in series with the main circuit, while the undervoltage trip coil aligns in parallel with the power supply. This comprehensive configuration ensures maximum protection and operational efficiency.
