15 A amperage rating with 240 V operation and a 42 kAIC interrupt rating across three poles. This combination delivers precise fault protection and fast interruption, reducing arc energy exposure and protecting downstream equipment. It is well suited for Type BR Loadcenters serving 3-phase motors and lighting circuits in commercial spaces and light industrial panels. Plug-on mounting in a Type BR 1-Inch form factor enables fast, clean panel installation. The direct plug-on connection minimizes wiring complexity and reduces installation time, helping technicians stay on schedule and lowering labor costs. This design excels in BR Loadcenters where space is at a premium and modular protection is essential for scalable control panels. Common trip across three poles ensures simultaneous disconnection of all live conductors during a fault. This enhances safety, simplifies NEC coordination, and improves maintenance scenarios where lockout-tagout procedures rely on predictable breaker behavior. Use this model for three-phase feeders in motor control centers and distribution panels requiring reliable multi-pole protection. Wire size compatibility of #14-4 AWG Cu/Al provides versatility in termination options. Terminations are straightforward, reducing termination errors and inventory complexity. This makes BRHH315 a practical choice for branch circuits in BR panels, enabling quick field upgrades without rewiring. UL 490 certification and Federal Specifications W-C376 compliance underpin regulatory readiness and asset protection. Catalog notes indicate options such as switching duty, HACR, shunt trip, and high magnetic settings for flexible protection schemes. This broad compatibility supports industrial and commercial installations where different trip characteristics matter. Warranty coverage includes limited lifetime residential and one-year commercial terms, delivering long-term value. This aligns with Eaton's reliability with service and documentation, aiding maintenance planning and ROI projections. For panel upgrades, facility operators can rely on proven BRHH315 performance in BR Loadcenters across varied environments.

FAQs
BRHH315 uses Type BR 1-Inch plug-on mounting designed for BR Loadcenters. It accepts #14-4 AWG Cu/Al conductors and operates at 240 V. The device is a three-pole circuit breaker with common trip and a 42 kAIC interrupt rating, providing straightforward terminations and reliable protection in compact panels.
A 42 kAIC interrupt rating indicates the breaker can interrupt high fault currents typical in commercial or light industrial feeders. This reduces arcing energy and improves downstream equipment safety. It supports coordination with upstream protection and enables reliable fault clearing in 3-phase circuits within BR Loadcenters.
Yes, BRHH315 is intended for Type BR Loadcenters and can protect 3-phase motors and related loads in commercial panels and light-industrial MCCs. Its 15 A rating and plug-on mounting simplify installation and enable scalable protection for evolving motor control layouts. For MCCs, ensure coordination with upstream devices and select appropriate trip settings like HACR or high magnetic when needed.
BRHH315 carries UL 490 certification and complies with Federal Specifications classification W-C376, aligning with safety and federal procurement requirements. These certifications support regulatory acceptance in building systems and ensure compatibility with standard BR Loadcenter products. The W-C376 compliance further confirms recognized performance for residential and commercial installations.
The BRHH315 carries Eaton's limited lifetime warranty for residential use and a one-year warranty for commercial applications, reflecting the brand's reliability. Warranty documentation and specification sheets are available from Eaton to assist with asset management, maintenance planning, and ROI projections during panel modernization.
