Product FAQs

6 answers
Which commercial panelboards accept the BAB2100?

The Quicklag BAB series is a bolt-on branch breaker designed for Eaton Pow-R-Line commercial panelboards, including the PRL1a, PRL2a, PRL1X, and PRL2X models. It also retrofits into older Westinghouse, Bryant, Cutler-Hammer, and Challenger bolt-on panels.

What is the difference between Eaton BAB and QBHW breakers?

Both are Quicklag bolt-on breakers that fit the same panelboards, but they feature different interrupting capacities. The BAB series offers a standard 10kAIC rating at 240V, while the QBHW series provides a higher 22kAIC rating. Verify your panel's required fault current before substituting.

Is the BAB2100 rated for direct current (DC) systems?

Yes. In addition to its alternating current rating, this breaker is rated for DC applications. It carries a 5kAIC interrupting rating at 24, 48, 62.5, and 80 VDC, making it suitable for certain battery and control panel circuits.

Can I install the BAB2100 in a residential plug-on load center?

No. This breaker features a bolt-on connection and is incompatible with plug-on residential load centers like the Eaton BR or CH series. It must be installed in a commercial panelboard equipped with a bolt-on bus.

How much panel space does the BAB2100 require?

This 2-pole breaker requires two standard 1-inch spaces in your panelboard.

Does the BAB2100 provide ground fault or arc fault protection?

No. This is a standard thermal-magnetic circuit breaker that provides essential Long-Time and Instantaneous trip protection against overloads and short circuits. It does not include built-in GFCI or AFCI circuitry.

    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.
