Enclosed circuit breakers are a solution for nearly every application requiring a means of disconnect. Our enclosed circuit breakers are a quick ship solution to the factory lead times regarding disconnects. When quoting we will need to know: amperage, voltage, enclosure type, and if a neutral is required. All components are individually UL rated. ECBs are Service Entrance Rated with standard components*.

ECB’s are molded case circuit breakers in a NEMA rated enclosure. Our standard ECBs are NEMA 1/3R/4/12 rated. We also can provide stainless steel enclosures (304 and 316) and explosion proof. We have the ability to customize these specifically to your needs. We have stock in flange and rotary style handle mechanisms. Breakers are available from 100A - 1200A frames.
