Product FAQs
7 answersWhich panelboards accept the BAB3090HS circuit breaker?
This bolt-on breaker is compatible with Eaton Pow-R-Line panelboards, as well as legacy Cutler-Hammer and Westinghouse enclosures designed for BAB series breakers.
What does the HS suffix mean on the BAB3090HS?
The HS suffix indicates that this breaker includes a factory-installed 120/208/240 VAC shunt trip. This allows the breaker to be tripped remotely via an external control signal, such as a fire alarm relay or emergency stop button.
Why use a bolt-on breaker like the BAB3090HS instead of a plug-on type?
Bolt-on breakers physically bolt directly to the panelboard bus, providing a highly secure, vibration-resistant connection. This makes them ideal for commercial and industrial applications where mechanical stress or continuous heavy loads might cause plug-on connections to loosen over time.
Is the BAB3090HS interchangeable with QBHW series breakers?
BAB and QBHW breakers share the same physical dimensions and bolt-on mounting style, but QBHW breakers have a higher interrupting rating (22 kAIC versus the 10 kAIC of the BAB). A QBHW breaker with a matching shunt trip can typically replace a BAB breaker, but you must verify that the higher rating is acceptable for your specific panelboard listing.
What does the LI trip function code mean for this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. The thermal (Long-Time) mechanism protects against sustained overloads, while the magnetic (Instantaneous) mechanism trips the breaker immediately during a severe short circuit.
Can I use aluminum wiring with the BAB3090HS?
Yes, the factory-installed box lugs are dual-rated for both aluminum and copper conductors. They accept wire sizes from 8 AWG up to 1/0 AWG.
What is the ambient temperature rating for the BAB3090HS?
This breaker is calibrated for a 40 degrees Celsius (104 degrees Fahrenheit) ambient operating temperature. Operating the breaker in environments significantly hotter than this may require derating to prevent nuisance tripping.

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.
