Product FAQs
6 answersWhat panelboards are compatible with the Eaton BAB2030 circuit breaker?
This bolt-on miniature breaker is designed for use in Eaton Pow-R-Line panelboards. It is also a direct fit for legacy commercial panelboards manufactured by Cutler-Hammer, Westinghouse, and Bryant that accept BAB frame breakers.
Is the BAB2030 breaker HACR rated for use with HVAC equipment?
Yes, the BAB2030 is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires a 2-pole, 30-amp overcurrent protection device.
Can I install the BAB2030 breaker in a standard residential load center?
No, the BAB2030 features a bolt-on connection designed specifically for commercial and industrial panelboards. It will not fit in standard plug-on residential load centers such as Eaton BR or CH series panels.
Is the Eaton BAB2030 a direct replacement for older Westinghouse versions?

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.
