Product FAQs

5 answers
What does the HS1 suffix indicate on this circuit breaker?

The HS1 suffix designates that the breaker includes a factory-installed 24-48VDC shunt trip mechanism. This feature allows the breaker to be tripped remotely using a low-voltage DC control signal, which is often required for emergency stop or specialized control circuits.

How much panel space is required to install the BAB3030HS1?

Because this breaker includes a factory-installed shunt trip mechanism, it requires one additional pole space on the right side. While it provides 3-pole protection, it will occupy four pole spaces in your panelboard.

Can I install the BAB3030HS1 in a standard residential load center?

No. The BAB3030HS1 is a bolt-on circuit breaker designed for commercial and industrial panelboards like the Eaton Pow-R-Line series. It will not fit in standard residential plug-on load centers that use Type BR or Type CH breakers.

Is this breaker branded as Eaton, Cutler-Hammer, or Westinghouse?

The BAB frame was originally developed by Westinghouse and later acquired by Cutler-Hammer, which is now part of Eaton. You may find this exact BAB3030HS1 breaker labeled under any of these three brands, and they are fully interchangeable within compatible panelboards.

What is the proper way to test the shunt trip mechanism after installation?

After wiring the control circuit to the shunt trip leads, apply the rated 24-48VDC control voltage. The breaker should trip immediately. Ensure the control power is removed before attempting to reset the breaker, as the handle will not latch if the shunt trip coil remains energized.

    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.
