Eaton BRHH2100 BR thermal magnetic circuit breaker - 42 kAIC
Part Number: BRHH2100
Quick Summary
The Eaton BRHH2100 BR thermal magnetic circuit breaker protects branch circuits in Type BR load centers. Engineers often confront tight panel spaces and wiring complexity, leading to miswiring or inconsistent protection. This unit carries UL 490 certification and Federal Specifications W-C376, with optional HACR, shunt trip, and high-magnetic settings to cover a range of protection schemes. For panel installations, the 1-Inch plug-on BR form factor, 100 A rating, and 42 kAIC interrupt capability deliver reliable protection while enabling simpler coordination across multi-pole configurations and streamlined spare-part inventories.

FAQs
Installation begins with confirming the panel's rated amperage and space per BR catalog notes. Slide the BRHH2100 into the 1-Inch bus bar and align with the proper mounting clip, then secure with mounting hardware. Wire the device using #4-1/0 AWG Cu/Al per the terminal markings. Ensure the unit is aligned for a common trip and verify tight, clean connections to prevent nuisance trips.
The BRHH2100 is rated for 100 A and operates at 120/240 V. This makes it suitable for residential, commercial, and light-industrial panelboards that require a two-pole, common-trip circuit breaker with high interrupt capability. Always confirm that the panel rating supports 100 A circuits and two-pole protection.
Yes. Catalog notes indicate options for HACR, shunt trip, and high-magnetic settings are available for the BR series. When selecting the device, specify the protection scheme required by the motor or control circuit, and verify compatibility with the panel and control wiring to ensure coordinated stopping and safe operation during fault conditions.
BRHH2100 is designed for Type BR Loadcenters and uses the standard plug-on mounting with a common trip. It is compatible with Type BR accessories and panels that support 1-Inch BR breakers. For upgrades or replacements, confirm the panel's catalog compatibility and ensure wire sizes and pole counts match the installed equipment.
BRHH2100 carries UL 490 certification and complies with Federal Specifications W-C376. These certifications indicate adherence to recognized safety and performance standards, which simplifies procurement, ensures regulatory compliance, and supports quality assurances in audits and safety programs across industrial, commercial, and utility environments.
