Product FAQs
6 answersWhat panelboards are compatible with the BAB3020C circuit breaker?
The BAB3020C is a bolt-on breaker designed for use in Eaton Pow-R-Line panelboards. It is also backward compatible with legacy Westinghouse and Cutler-Hammer panelboards that accept BAB frame breakers.
What does the "C" in the BAB3020C catalog number indicate?
The "C" designates this model as a switching neutral circuit breaker. While it occupies three pole spaces in the panel, one of the poles is specifically designed to disconnect the neutral conductor alongside the ungrounded conductors.
Is the Eaton BAB3020C breaker HACR rated?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment branch circuits.
How does the BAB3020C install into the panelboard?
This is a bolt-on circuit breaker. It physically bolts directly to the panelboard bus bar, providing a secure, vibration-resistant connection commonly required in commercial and industrial applications.
Can I use the BAB3020C to replace an older Westinghouse BAB breaker?
Yes. Eaton acquired the Westinghouse distribution equipment division, so the modern Eaton BAB3020C is a direct, exact replacement for older Westinghouse or Cutler-Hammer breakers with the same catalog number.
Can the BAB3020C be used in DC voltage applications?
No. Eaton BAB series breakers are strictly rated for AC voltage and do not carry a DC rating.

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.
