FAQs
Install the BRHH330 as a plug-on, three-pole device into a compatible Type BR load center. Verify the conductor size (#14-4 AWG Cu/Al) and tighten connections to the manufacturer’s torque specs. Ensure the breaker’s amperage rating (30 A) matches the circuit design and that the unit is correctly seated to enable the common trip function and proper interrupt performance.
BRHH330 is a 30 A, 240 V thermal magnetic circuit breaker with a 42 kAIC interrupt rating. It is a three-pole, plug-on device used with Type BR Loadcenters. It carries UL 490 certification, is compatible with #14-4 AWG Cu/Al conductors, and supports a common trip configuration for coordinated protection in protection panels.
Yes. The three-pole, 30 A, 240 V BRHH330 provides robust short-circuit and overload protection appropriate for motor control panels and industrial equipment. Its 42 kAIC interrupt rating helps manage higher fault energies typical in industrial drives, and the common trip feature simplifies protection coordination across multiple circuits within a BR Loadcenter.
BRHH330 carries UL 490 certification and complies with Federal Specifications W-C376. It also supports HACR and shunt-trip options, making it suitable for regulated environments and applications requiring specific safety and control features.
The BRHH330 carries Eaton’s limited lifetime warranty for residential use and a 1-year warranty for commercial installations. For detailed terms, consult the warranty document in Eaton’s resources. Routine inspections of terminals, periodic testing, and prompt replacement after faults help maintain reliable protection and performance.
