Product FAQs
8 answersWhich panelboards are compatible with the BAB1025 circuit breaker?
The BAB1025 is compatible with modern Eaton Pow-R-Line panelboards. It is also designed to fit legacy Westinghouse, Cutler-Hammer, and Bryant panelboards that accept bolt-on BAB frame breakers.
Will the BAB1025 fit in a standard residential plug-on load center?
No. The BAB1025 features a bolt-on connection designed specifically for commercial and industrial panelboards. It cannot be used in Eaton BR, CH, or other residential load centers that require plug-on or snap-in breakers.
What are the terminal torque specifications for installing the BAB1025 breaker?
Eaton specifies a terminal torque of 20 in-lbs for 14 to 10 AWG wire, 25 in-lbs for 8 AWG wire, and 27 in-lbs for 6 to 4 AWG wire.
How much space does the BAB1025 occupy in a panelboard?
As a 1-pole miniature circuit breaker in the Quicklag family, the BAB1025 requires a single 1-inch wide space on the panelboard bus.
Is the BAB1025 rated for heating, refrigeration, and commercial lighting loads?
Yes, this miniature circuit breaker is HACR rated for heating, air conditioning, and refrigeration equipment. It is also rated for High Intensity Discharge (HID) lighting applications.
Can the BAB1025 be used in DC electrical applications?
Yes. While primarily rated for 120/240V AC systems, it also carries specific direct current ratings. It is rated to safely interrupt 5 kAIC at 24V or 48V DC, and 3.8 kAIC at 62.5V DC.
How does the thermal-magnetic trip unit protect the electrical circuit?
The BAB1025 features both fixed thermal and fixed magnetic trip elements. The thermal component provides long-time delay protection against sustained overloads, while the magnetic component triggers an instantaneous trip to safely clear severe short circuits.
Can the Eaton BAB1025 replace legacy Cutler-Hammer or Westinghouse breakers?
Yes. Eaton acquired these legacy brands and continues to manufacture the Quicklag BAB line. The modern Eaton BAB1025 is a direct, exact replacement for older Cutler-Hammer, Westinghouse, and Bryant breakers bearing the same BAB1025 catalog number.

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.
