Introduction
Experience intelligent safety with the DAM3-1600 molded case circuit breaker, an advanced device engineered to automatically disconnect power when current exceeds its pre-set release threshold. This cutting-edge system is housed in a molded case crafted from resilient plastic insulator, constructing the frame and efficiently insulating the conductor alongside metal grounding components, ensuring safe and reliable operation.
Working principle
Precision meets protection in the DAM3-1600 molded case circuit breaker, featuring a main contact controllable both manually and through electric closing. Once secured in the closed position by a reliable free release mechanism, it stands vigilant. The overcurrent trip coil and thermal trip element, intricately linked in series with the main circuit, provide rapid response to overcurrent, while the undervoltage trip coil, strategically connected in parallel with the power supply, guarantees unwavering protection against voltage drops.
