Enclosed Circuit Breakers for a Variety of Applications
Our enclosed circuit breakers are offered in steel, stainless steel, and fiberglass enclosures for use in a variety of applications and environments. They consist of a thermal magnetic molded case circuit breaker mounted in a UL listed circuit breaker enclosure with a through the door handle for operation. The handle mechanism does not allow the cover to be opened without the breaker being in the OFF position. This is a safety precaution that de-energizes components in the panel. Neutral assemblies are offered as an option.
The ABB Tmax molded case circuit breakers offered here are fitted with thermomagnetic trip units. All ABB circuit breakers in accordance with the UL 489 and CSA C22.2 standard can be used in installations with wye or delta distribution systems since use of the circuit breaker at 480V AC is guaranteed, even for the smallest Tmax T1 size.
