Introduction
The DAM3-1000 Molded Case Circuit Breaker is engineered to automatically interrupt current flow when it exceeds the preset release setting, offering reliable protection and operational integrity. The term 'molded case' refers to the durable plastic insulator that forms the frame of the device, ensuring comprehensive insulation between the conductor and metal grounding components.
