FAQs
Installation begins by verifying system voltage (120/240 V) and confirming the panel is designed for Type BR Loadcenters. Mount the BRH2125BP50 as a 1-Inch plug-on breaker, connect #4-1/0 AWG Cu/Al conductors to the appropriate terminals, and snap the unit into a compatible BR Loadcenter bus. Ensure the handle aligns for a common-trip configuration when used with multi-pole arrangements. Finally, inspect wiring for tightness, close the panel, and test the circuit in accordance with local electrical codes and the product datasheet.
The BRH2125BP50 provides a 125 A rating with a 22 kAIC interrupt rating, enabling rapid and safe interruption of high fault currents. Its thermal-magnetic trip mechanism balances overload protection with selectivity, reducing nuisance trips. The common-trip design ensures coordinated disconnection across paired poles, which is essential for multi-wire branch circuits and NEC compliance in many commercial applications.
Yes. The BRH2125BP50 is specifically designed for Type BR Loadcenters and supports bulk-pack deployment. Its 1-Inch plug-on form factor, 120/240 V rating, and two-pole configuration make it well-suited for residential distribution panels and light-commercial installations seeking reliable protection with streamlined maintenance and stocking.
This model carries UL 490 certification and complies with Federal Specifications W-C376. Catalog notes indicate availability with HACR, shunt-trip, and high-magnetic settings, enabling tailored protection for HVAC or high-demand applications while maintaining compliance with current electrical safety standards.
Bulk-pack BR breakers reduce procurement complexity and unit costs, lowering maintenance labor and inventory management time.
