Eaton / Westinghouse HQP3020H Miniature Circuit Breaker

Yes. Because Eaton acquired Westinghouse's electrical distribution division, this breaker is fully compatible with both modern Eaton Pow-R-Line panelboards and legacy Westinghouse Pow-R-Line panelboards that accept plug-on Quicklag breakers.

Yes. Eaton acquired the Cutler-Hammer and Westinghouse electrical distribution lines. The HQP3020H is the exact same breaker across all three brand names and serves as a direct drop-in replacement.

No. It features a Quicklag plug-on design that snaps directly onto the busbar of compatible Pow-R-Line panelboards, allowing for faster installation compared to bolt-on alternatives.

It utilizes an "LI" trip curve, combining a thermal element for Long-Time protection against sustained overloads and a magnetic element for Instantaneous tripping during severe short circuits.

No. Both the thermal overload and magnetic short-circuit trip points are fixed at the factory. They cannot be adjusted in the field to accommodate different load profiles.

No. The factory-installed box lugs natively accept wire gauges from 14 AWG up to 4 AWG, allowing you to terminate standard conductors directly without additional adapters.

The HQP3020H has a standard interrupting rating of 10kAIC at 240V. The QPHW3020H is the higher interrupting capacity version of the exact same breaker, offering 22kAIC for systems requiring greater fault current protection.

No. While they share similar electrical specifications, the HQP3020H is a plug-on breaker designed for Pow-R-Line panels that accept plug-on connections. The BAB3020H is a bolt-on breaker and requires a panelboard designed for bolted connections.

Yes. This breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires specialized overcurrent protection.
