Introduction
The DAM3-1600 molded case circuit breaker represents the pinnacle of intelligent design, ensuring optimum safety by automatically disconnecting power when current levels exceed its pre-set thresholds. This advanced system is encased within a robust molded case, expertly constructed from a durable plastic insulator. This not only forms the frame of the device but also provides efficient insulation for the conductor and metal grounding components, offering unparalleled protection and reliability.
Working principle
Designed with meticulous precision, the DAM3-1600 molded case circuit breaker features a main contact that can be deftly controlled either manually or via electric actuation. Once secured in the closed position by its responsive free release mechanism, it is ever-ready to safeguard your electrical systems. The overcurrent trip coil and thermal trip element, ingeniously linked in series with the main circuit, react swiftly to any excess current. Meanwhile, the undervoltage trip coil, connected in parallel with the power supply, guarantees steadfast protection against voltage drops, making this device a cornerstone of reliable circuit protection.
