The PowerPact B-frame circuit breaker is designed to offer robust power protection in a compact size and "efficiency that clicks" to the work day. The 125 A B-frame circuit breaker is the smallest Square D molded case circuit breaker offered in the PowerPact range. It utilizes economical, thermal magnetic sensing elements and is designed to be flexible and offer integrated DIN rail and back-pan mounting capabilities without extra adapter brackets. A wide variety of external mechanical operators for control panel applications complement field-installable electrical accessories. PowerPact B circuit breakers also feature EverLink creep-compensating lug technology. This spring-based power terminal system ensures a lasting connection by mitigating the loosening effects of heat cycling or vibration. The lugs are UL listed for use directly with stranded and fine-stranded wire up to Class K. EverLink lugs are even offered with optional built-in control wire terminals.
