Additional Information

  • The PowerPact B-frame circuit breakers are designed and certified to multiple standards in order to meet the needs of customers who have global designs or build and sell in regions with various standards. One product can be used and sourced globally.
  • B-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.
    They are available with thermal-magnetic trip units from 15 to 125 A, with a breaking capacity up to 65 kA at 480 Vac and 50 kA at 250 Vdc.
  • The B-frame circuit breakers are offered in 1, 2, and 3-pole versions in both I-Line and unit-mount constructions. There is also a 4-pole version, offered in unit mount construction only, with a 100% protected neutral located in the far left pole. It is used in countries where the neutral is also switched (not typical for USA domestic applications).
  • The B-frame product offers a flexible platform in which customer needs for various types of mounting and terminations can be accommodated with simple alterations of the base product. Field installable features and termination variety empower the customer to configure the product to their exact needs for control panel or power panel applications.
  • B-frame circuit breakers with thermal-magnetic trip units contain individual thermal (overload) and instantaneous (short circuit) sensing elements in each pole. The amperage ratings of the thermal trip units are calibrated at 40°C (104°F) free air ambient temperature. 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.

PowerPact B-frame circuit breakers have an over-center toggle mechanism providing quick-make, quick-break operation. The operating mechanism is also trip-free, which allows tripping even when the circuit breaker handle is held in the “ON” position.

Internal cross-bars provide common opening and closing of all poles with a single “ON” position.

All PowerPact circuit breakers have an integral push-to-trip button in the cover to manually trip the circuit breaker. This should be used as part of a regular preventive maintenance program.
