Product FAQs
5 answersWhat panelboards are compatible with the BAB3070H circuit breaker?
This bolt-on miniature breaker mounts directly into Eaton Pow-R-Line load centers, specifically the PRL1a, PRL2a, PRL3a, and PRL4a series panelboards.
Can the BAB3070H be used as a direct replacement in legacy panelboards?
Yes. Eaton currently manufactures the Quicklag BAB series to be fully backwards compatible with older bolt-on load centers originally branded by Westinghouse, Cutler-Hammer, Bryant, and Challenger.
What does the H suffix in the BAB3070H catalog number indicate?
The H designation signifies a maximum voltage rating of 240V AC. This allows the breaker to be safely used on 240V Delta or 208Y/120V 3-phase systems, whereas standard non-H models are restricted to 120/240V applications.
Is the BAB3070H suitable for protecting air conditioning systems?
Yes, Eaton Quicklag BAB circuit breakers up to 100 amps are HACR rated. This certification ensures the breaker can safely handle the inrush currents of heating, air conditioning, and refrigeration motor loads.
Can I use the BAB3070H to replace a QBHW3070 breaker?
Both series share the identical Quicklag bolt-on footprint, but they have different interrupt ratings. The BAB3070H is rated at 10kAIC, while the QBHW series is rated at 22kAIC. Only substitute the BAB3070H if your system's available fault current is safely below 10,000 amps.

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.
