Eaton BRHH115 Thermal Magnetic Circuit Breaker - UL 490
Part Number: BRHH115
Quick Summary
The Eaton BRHH115 thermal magnetic circuit breaker is a compact, plug-on protection device designed for Type BR loadcenters. Engineers often struggle to fit reliable overcurrent protection into tight panel spaces without compromising trip performance. UL 490 listing and Federal Specifications W-C376 compliance, along with HACR-capable options, help ensure regulatory adherence for HVAC and general circuits. With a 15 A rating, 120/240 V operation, and a common trip for multi-pole configurations, BRHH115 delivers dependable protection while simplifying installation for panel builders. This part aligns with BR loadcenters and standard conductor sizes, reducing procurement complexity and speeding commissioning in industrial and commercial panels.

Feature: Thermal magnetic trip provides automatic overload and short-circuit protection. Business impact: Delivers reliable, fast response to abnormal current, reducing downtime and equipment damage. Application: Ideal for branch circuits in Type BR loadcenters where space is at a premium and coordinated protection is required. Feature: Common trip with single-pole design enables synchronized disconnection across related circuits. Business impact: Improves safety and reduces nuisance tripping in multi-wire installations. Application: Perfect for panelboards employing shared neutrals and coordinated protection in commercial environments. Feature: Plug-on mounting simplifies installation and minimizes panel-wiring errors. Business impact: Cuts installation time, lowers field labor costs, and reduces commissioning bottlenecks. Application: Suitable for rapid upgrades in existing BR loadcenters and new panel builds. Feature: 42 kAIC interrupt rating supports higher fault-current environments. Business impact: Enhances system safety and regulatory compliance in industrial settings. Application: Use where fault currents exceed standard residential levels. Feature: Wire size flexibility with #14-4 AWG Cu/Al. Business impact: Broadens conductor compatibility, reducing stocking variety. Application: Common in residential and light commercial wiring schemes. Feature: Certifications and compliance (UL 490, W-C376) provide regulatory assurance. Business impact: Streamlines procurement and installation across code-driven projects. Application: Required for building codes and safety programs in new constructions.

FAQs
BRHH115 uses a plug-on mounting on a Type BR bus. Disconnect power, remove the panel cover, align the breaker with the BR bus, and firmly snap it into place. Use #14-4 AWG Cu/Al conductors and ensure proper torque on terminations. Verify 120/240 V operation and the single-pole, common-trip configuration before restoring power.
42 kAIC indicates the maximum fault current the breaker can interrupt safely without internal damage. This rating supports higher fault levels in many commercial or industrial panels, reducing the risk of cascading trips or equipment damage during short circuits. Always confirm the panel’s short-circuit current rating aligns with this spec.
Yes. The 15 A rating, 120/240 V operation, and common-trip capability make BRHH115 appropriate for residential branch circuits and light commercial panels. Its compact 1-inch plug-on design helps maximize space in Loadcenter assemblies, while UL 490 and W-C376 compliance support regulatory expectations across applications.
BRHH115 is UL 490 listed and complies with Federal Specifications W-C376. It also supports HACR switching duty as noted in catalog documentation. These certifications certify safety performance, suitability for HVAC and general circuits, and align with building codes and procurement standards.
BRHH115 is designed for long-term reliability with a limited lifetime warranty for residential use and a one-year warranty for commercial installations. Routine inspection should verify secure terminations and clean, corrosion-free contacts. Replace following any tripping anomalies, visible damage, or wear that could compromise protection or regulatory compliance.
