Product FAQs
8 answersWhich panelboards accept the BAB3100HS breaker?
It is a bolt-on breaker engineered for Eaton Pow-R-Line series panelboards and legacy Westinghouse panelboards designed for Quicklag frame breakers. It will not fit in standard plug-on residential load centers.
What does the 'HS' suffix indicate in the BAB3100HS catalog number?
The 'HS' suffix designates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely by an external voltage signal, a common requirement for emergency shutdown systems and building automation.
What wire size is correct for the box lugs on this 100A breaker?
While some generic descriptions state a smaller range, the correct wire capacity for this 100A Quicklag breaker is #8 to 1/0 AWG for both copper and aluminum conductors. Always torque the lugs to the manufacturer specifications printed on the breaker label.
Can I install the BAB3100HS if my panel calls for a standard BAB3100?
You can, but it is not recommended unless you need the 120VAC remote trip capability. The 'HS' variant includes extra coil wires for the shunt trip. If you simply need standard overcurrent protection, use the base BAB3100 catalog number.
Are Cutler-Hammer and Eaton BAB breakers interchangeable?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture the Quicklag line. A modern Eaton BAB breaker is an exact drop-in replacement for legacy Cutler-Hammer and Westinghouse BAB series breakers.
Is the BAB3100HS approved for HVAC equipment?
Yes. Like most of the Eaton Quicklag BAB family, this breaker is HACR rated, making it fully approved by the NEC for protecting heating, air conditioning, and refrigeration motor circuits.
How is the shunt trip reset after being activated?
When a 120V signal is applied to the shunt coil, the breaker handle will move to the center tripped position. To restore power, you must first remove the 120V control signal, manually push the handle fully to the Off position to reset the internal mechanism, and then switch it to On.
Can this 240VAC breaker be used on a 208Y/120V system?
Yes. The 240VAC rating is a maximum voltage threshold. This three-pole breaker is perfectly suited for standard three-phase, four-wire 208Y/120V commercial applications.

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.
