Product FAQs
7 answersWhat panelboards are compatible with the Eaton BAB1070 circuit breaker?
The BAB1070 is designed for use in Eaton Pow-R-Line, Westinghouse, and legacy Cutler-Hammer bolt-on panelboards that accept Quicklag B-frame breakers. It is not compatible with standard residential plug-on load centers like the BR or CH series.
Can I use the BAB1070 to replace older Westinghouse or Cutler-Hammer breakers?
Yes, the Eaton BAB1070 is a direct, exact replacement for legacy Westinghouse and Cutler-Hammer Quicklag BA and BAB 70A 1-pole bolt-on breakers.
What is the difference between the Eaton BAB1070 and the QBHW1070?
Both are 70A, 1-pole bolt-on breakers with the same physical footprint. The difference is the interrupting capacity. The BAB1070 is rated at 10kAIC, while the QBHW1070 is rated for 22kAIC.
How does the BAB1070 mount into the panelboard?
This breaker features a bolt-on connection. It physically bolts directly to the panelboard busbar, providing a secure, vibration-resistant connection commonly required in commercial and industrial applications.
What wire sizes are accepted by the BAB1070 box lugs?
The terminal lugs on the BAB1070 accept 8 AWG to 1/0 AWG copper or aluminum conductors. Ensure you follow local electrical codes for proper wire sizing based on the 70A rating and application.
Can the BAB1070 be used in DC voltage applications?
Yes, in addition to its standard 120/240VAC rating, the BAB1070 is rated for 5kAIC at 24VDC and 48VDC, making it suitable for specific low-voltage direct current control circuits.
What type of trip mechanism does the BAB1070 use?
It utilizes a fixed thermal magnetic trip mechanism. The thermal element provides long-time protection against persistent overloads, while the magnetic element offers instantaneous protection against short circuits.

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.
