FAQs
To install BRH390, ensure you are using Type BR Loadcenters compatible with a 1-Inch plug-on circuit breaker. Connect #4-1/0 AWG Cu/Al conductors within the rated 90 A and 22 kAIC, secure the breaker firmly in the panel bus, and verify that the three-pole assembly is correctly coordinated with any upstream protective devices. Follow standard torque specs from the manufacturer’s installation guide.
The BRH390 supports 90 A continuous current and offers a 22 kAIC interrupt rating. It is a 3-pole, 240 V device with a common-trip design, Type BR, and a 1-Inch plug-on form factor designed for BR Loadcenters. It is suitable for residential, commercial, and light-industrial panel applications requiring quick fault clearing.
Yes. The BRH390 includes HACR-capable settings as indicated in its catalog notes, allowing it to be used with heating, air conditioning, and refrigeration equipment in appropriate installations. This helps maintain code compliance and reduces the risk of nuisance trips in HVAC-involved panels.
The BRH390 is UL 490 listed and complies with Federal Specifications W-C376. These certifications validate safety performance and regulatory acceptance, simplifying procurement for building codes, insurance requirements, and panel assembly in commercial and light-industrial projects.
The BRH390’s robust trip performance and common-trip design reduce nuisance trips and unplanned outages, improving panel uptime. Its compatibility with BR Loadcenters streamlines installation and retrofit projects, lowering labor costs and commissioning time, while UL 490 certification supports long-term regulatory compliance and asset protection.
