Product FAQs

6 answers
What panelboards are compatible with the BAB3070E circuit breaker?

This bolt-on breaker is designed for use in Eaton Pow-R-Line panelboards, as well as legacy Westinghouse and Cutler-Hammer panelboards that accept BAB-frame breakers.

What does the "E" suffix mean in the BAB3070E catalog number?

The "E" suffix designates this as an international-rated circuit breaker. It provides a 3kA interrupting capacity at 415V to meet BS3871 standards, in addition to its standard 240V ratings.

What is the advantage of the bolt-on connection for the BAB3070E?

Unlike plug-on breakers, the bolt-on design fastens directly to the panelboard bus with screws. This prevents the breaker from vibrating loose in industrial environments and ensures a secure, high-reliability connection.

Can I use the BAB3070E to replace older Cutler-Hammer or Westinghouse breakers?

Yes, Eaton manufactures the BAB3070E as a direct, authentic replacement for older Cutler-Hammer and Westinghouse BAB series breakers with the same specifications.

Does the BAB3070E include ground fault or arc fault protection?

No, this is a standard thermal-magnetic breaker with long-time and instantaneous trip functions. It does not provide GFCI or AFCI protection.

How does the thermal-magnetic trip unit operate on this breaker?

It features a fixed trip unit where the thermal element protects against sustained overloads by heating up and tripping over time, while the magnetic element trips instantly in the event of a short circuit.

    Excellent Experience

    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.
