Product FAQs
6 answersWhat does the "S" suffix indicate on the BAB2035S catalog number?
The "S" suffix designates that this breaker is equipped with a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely for emergency shutdowns or automated control systems.
How does the 120VAC shunt trip function operate on the BAB2035S?
The shunt trip requires an external 120VAC control signal. When voltage is applied to the shunt trip coil, it mechanically forces the breaker to open, disconnecting power to the load. The shunt trip coil draws approximately 2.6A at 120VAC during the tripping action.
Can the BAB2035S replace older Westinghouse breakers?
Yes, the BAB2035S serves as a direct replacement for legacy Westinghouse QNBL2035 shunt trip breakers.
Is the BAB2035S suitable for use with heating and air conditioning equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 35-amp overcurrent protection device.
How is the BAB2035S installed into a panelboard?
This breaker features a bolt-on connection. It must be mechanically bolted directly to the busbar of a compatible Eaton Pow-R-Line, Cutler-Hammer, or Westinghouse panelboard. It cannot be used in plug-on load centers or DIN rail applications.
How much panel space does the BAB2035S require?
As a 2-pole miniature circuit breaker in the Quicklag family, the BAB2035S requires two standard 1-inch spaces in a compatible panelboard.

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.
