Product FAQs
6 answersDoes the BAB2050 snap into the panel like a standard residential breaker?
No, the BAB2050 requires a bolt-on connection. It physically screws into the busbar of compatible Eaton Pow-R-Line, Cutler-Hammer, or Westinghouse commercial panelboards rather than plugging into place.
Is the BAB2050 suitable for HVAC equipment?
Yes. Like all Eaton BAB series breakers between 15A and 100A, the BAB2050 is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration systems.
Can the BAB2050 handle direct current (DC) systems?
Yes, this thermal-magnetic breaker is dual-rated for both AC and DC applications. It safely interrupts up to 5kA at 24VDC or 48VDC, and 3.8kA at 62.5VDC.
How does the BAB2050 differ from the QBHW2050 and HBAX2050?
All three belong to the Eaton Quicklag bolt-on family and share identical mounting footprints, but their short-circuit interrupting ratings differ. The BAB2050 is rated for 10kAIC, the QBHW2050 for 22kAIC, and the HBAX2050 for 65kAIC.
Can I use the Eaton BAB2050 to replace an older Westinghouse BAB breaker?
Yes. Eaton acquired Westinghouse's electrical distribution division and continues to manufacture the Quicklag BAB series to the exact same specifications. An Eaton BAB2050 is a direct, code-compliant replacement for an older Westinghouse BAB2050.
Does the BAB2050 provide arc fault (AFCI) or ground fault (GFCI) protection?
No. The BAB2050 is a standard thermal-magnetic breaker that provides essential overload and short-circuit protection. It does not contain AFCI or GFCI circuitry. For bolt-on ground fault protection, a QBGFT series breaker is required.

We placed our first order with superbreakers.com recently for a breaker we weren't able to acquire locally. I ordered the breaker way ahead of time because I've had issues with shipping for products purchased online in the past. The estimate for the item when I initially ordered was 3 days. Without adding an expedited shipping options, the breaker arrived the next day. We installed it this week, and so far so good. In my opinion, they sell quality parts and have excellent turn around time. Very impressed.
