FAQs
BRH325 is a Type BR 1-Inch plug-on circuit breaker designed specifically for Type BR load centers. It wires with #14-4 AWG Cu/Al and mounts in a plug-on fashion, enabling quick swaps or upgrades without reconfiguring the panel bus. This reduces downtime and ensures consistent electrical performance across the distribution system.
The BRH325 offers a 25 A rating, 240 V operating voltage, and a 22 kAIC interrupt rating, providing robust short-circuit protection for typical commercial and light industrial circuits. Its common-trip three-pole design ensures coordinated disconnection across all poles during a fault, improving safety and reducing insulation damage in multi-wire circuits.
Yes. BRH325 is a three-pole, plug-on circuit breaker intended for Type BR load centers, which commonly support three-phase installations. Its three-pole configuration ensures synchronized tripping across all phases, which is essential for balanced protection in three-phase panel boards and motor circuits.
BRH325 carries UL 490 certification and complies with Federal Specifications W-C376. These credentials help ensure regulatory alignment, simplify parts approval for inspection, and support warranty and compliance documentation during audits across commercial and light industrial facilities.
The plug-on design and standardized 3-in-3-in-3-in footprint streamline installation and future maintenance, reducing labor time. With a 25 A rating, 240 V operation, and a 22 kAIC interrupt rating, the device supports reliable protection, potentially lowering downtime and maintenance costs while improving system availability over the lifecycle of BR load centers.
