Product FAQs
5 answersWhich panelboards are compatible with the QBHW2100 circuit breaker?
The QBHW2100 is a bolt-on breaker designed for use in Eaton Pow-R-Line panelboards, including the PRL1a, PRL2a, and PRL3a series. It is also backward compatible with legacy Westinghouse and Cutler-Hammer panelboards that accept Quicklag-B frame breakers.
What is the difference between Eaton BAB and QBHW circuit breakers?
Both BAB and QBHW are Quicklag-B frame bolt-on breakers with identical physical dimensions. The primary difference is their interrupting capacity. BAB breakers are rated for 10kAIC, while QBHW breakers have a higher 22kAIC rating. The QBHW2100 can safely replace a BAB2100 if the panel requires a higher fault current rating.
How does the QBHW2100 connect to the panelboard busbar?
This breaker features a bolt-on connection. It fastens directly to the panelboard busbar using screws, providing a secure, vibration-resistant connection that prevents flexing in commercial and industrial environments.
Can the Eaton QBHW2100 replace older Westinghouse breakers?
Yes. Eaton acquired the Westinghouse distribution equipment line, so the Eaton QBHW2100 is the direct, exact replacement for older Westinghouse and Cutler-Hammer breakers sharing the QBHW2100 catalog number.
Is the QBHW2100 HACR rated for HVAC applications?
Yes, Eaton Quicklag miniature circuit breakers from 15A to 100A, including the QBHW2100, are HACR rated. This makes them suitable for use with heating, air conditioning, and refrigeration equipment.
