Product FAQs

6 answers
What panelboards are compatible with the BABF1020 circuit breaker?

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

Can I use the BABF1020 to replace older Westinghouse BAB breakers?

Yes. Eaton acquired the Westinghouse distribution equipment division, making the BABF1020 a direct replacement for older Westinghouse and Cutler-Hammer BAB breakers with matching specifications.

What does the F in the BABF1020 catalog number indicate?

The F designates this as a Fire Alarm Circuit Breaker. It is specifically designed to meet NFPA 72 requirements for dedicated fire alarm system circuits.

Does the BABF1020 require red tape or markers for fire alarm identification?

No. As a designated fire alarm circuit breaker, it is manufactured to provide clear, professional identification for fire alarm circuits without the need for field-applied red tape or markers.

What type of protection does the LI trip function provide?

The fixed thermal-magnetic trip unit provides Long-Time (L) protection for thermal overloads and Instantaneous (I) protection for magnetic short circuits.

How does the BABF1020 install into the panelboard?

It features a bolt-on connection, meaning it physically bolts to the panelboard bus rather than snapping into place. This provides a secure, vibration-resistant connection typical in commercial and industrial applications.

    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.
