Learn MoreB-frame circuit breakers have the smallest footprint in the PowerPacT family of industrial molded case circuit breaker products from Square D™ by Schneider Electric™. PowerPacT B-frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits.
PowerPacT B-frame circuit breakers are used for various circuit protection and switching functions in industrial control panels. They serve as an incoming main circuit breaker and control panel disconnect, as branch circuit protective devices for final loads, or as feeder circuit protective devices (often combined with motor starters).
The DD-Frame is also available as a switch. Optional auxiliary switch and trip alarm. Due to it's robust frame and ability to withstand harsh environments, the DD Frame breaker is used in military and railway applications, and in renewable energy solutions for protection of combiner boxes and battery storage.
The standard unit-mount and I-Line circuit breakers have sealed trip units and may be reverse fed. The B-frame circuit breaker complies with the following special ratings: B-frame 15–60 A circuit breakers are UL Listed/CSA Certified to be applied at up to 100% of their current rating.
The B-frame circuit breakers are offered in one-, two-, and three-pole versions in both I-Line and unit-mount constructions. There is also a four-pole version, offered in unit mount construction only, with a 100% protected neutral located in the far left pole.
Per the National Electric Code ® (NEC ®) and the Canadian Electrical Code, standard circuit breakers may only be applied continuously at up to 80% of their rating. All PowerPacT B-frame circuit breakers are equipped with dual-break rotating contacts that reduce the amount of peak current during a short circuit fault.
