Introduction
The DAM3-1000 molded case circuit breaker is engineered to automatically disconnect the current when it surpasses the pre-set release threshold. The term 'molded case' refers to the plastic insulator that forms the device's frame, ensuring effective insulation of conductors and metal grounding components, thereby providing robust protection and reliability.
