Introduction
The DAM3-1600 molded case circuit breaker stands as an intelligent guardian, ensuring safety with its automatic power cutoff feature when current levels exceed the pre-set release threshold. This advanced device employs a molded case, expertly crafted from durable plastic insulator, forming the resilient frame that efficiently insulates both the conductor and metal grounding components, ensuring enduring performance.
Working principle
Operating with unparalleled precision, the DAM3-1600 molded case circuit breaker features a main contact controllable either manually or through electric closure. Once secured in the closed position by a free release mechanism, it stands vigilant and ready to protect. The overcurrent trip coil and thermal trip element, intricately linked in series with the main circuit, swiftly respond to excess current. Simultaneously, the undervoltage trip coil, connected in parallel with the power supply, guarantees steadfast protection against voltage drops, reinforcing its role as a reliable safeguard.
