Introduction
The DAM3-1600 molded case circuit breaker is an advanced, intelligent device engineered to ensure safety by automatically severing the power when the current surpasses its pre-set release threshold. This sophisticated system features a molded case, constructed from durable plastic insulator, which forms the robust frame of the device, effectively insulating the conductor and metal grounding components.
Working principle
Operating with unwavering precision, the DAM3-1600 molded case circuit breaker is equipped with a main contact, controllable either manually or through electric closing. Once securely locked in the closed position via the 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 react to excess current, while the undervoltage trip coil, strategically connected in parallel with the power supply, provides steadfast protection against voltage fluctuations.
