Three-pole design with a 100 A rating and 240 V supply provides coordinated protection across all phases, reducing miscoordination and downtime. The 42 kAIC interrupt rating enables safe interruption of high fault currents, supporting motor feeders and large branch circuits in industrial environments. Plug-on mounting and a Type BR 1-Inch form factor streamline installation, cutting labor time and minimizing wiring errors in BR Loadcenters. Wire-size compatibility with #4-1/0 AWG Cu/Al simplifies panel wiring and inventory management, enabling direct connections to main lugs and bus bars. UL 490 certification and Federal Specifications W-C376 compliance help ease regulatory audits and QA checks, reinforcing risk management during commissioning. Catalog notes indicating HACR, shunt-trip, and high-magnetic settings provide flexibility for future-proofing protection against motor loads and hazardous environments.

FAQs
The BRHH3100 is a Type BR 1-Inch plug-on circuit breaker, designed for plug-on mounting in BR Loadcenters. It accepts #4-1/0 AWG Cu/Al conductors and is a three-pole device with a common trip. For best results, verify panel rating matches 100 A at 240 V and ensure space and bus stabs align with the Type BR form factor to facilitate a quick, error-free swap.
With a 100 A amperage rating and 240 V operating voltage, the BRHH3100 provides robust protection for medium-to-heavy feeders. Its 42 kAIC interrupt rating supports safe fault interruption, reducing conductor and equipment damage. The three-pole common-trip design ensures coordinated protection across all phases, which is essential for balanced load distribution in industrial panels.
Catalog notes indicate BR-series devices offer HACR, shunt-trip, and high-magnetic settings for selected amperages. While the BRHH3100 supports the BR family protections, always confirm the exact configuration with the datasheet. In practice, HACR-capable variants help reduce motor heat concerns, and high-magnetic settings improve startup protection for motor loads in manufacturing environments.
The BRHH3100 carries UL 490 certification and complies with Federal Specifications W-C376. This combination supports code-compliant panel protection, safer installation practices, and audit-ready documentation. Rigorous standards alignment helps buyers meet industry and governmental requirements while maintaining consistent protection across BR Loadcenters.
Key documents are available from Eaton, including the Specification Sheet for BRHH3100 and the limited warranty guide. The specification sheet provides electrical ratings, installation notes, and compatibility details, while the warranty document outlines coverage terms. These resources aid procurement, commissioning, and long-term maintenance planning.
