Product FAQs
7 answersWhich panelboards are compatible with the BAB3070HS circuit breaker?
This bolt-on breaker is designed for use in Eaton Pow-R-Line panelboards, including PRL1X, PRL2X, and PRL3a series, as well as legacy Westinghouse panelboards that accept BAB frame breakers.
What does the "HS" suffix indicate on the BAB3070HS catalog number?
The "HS" suffix designates that this breaker includes a factory-installed 120VAC shunt trip, allowing for remote tripping of the circuit breaker via an emergency stop or control circuit.
Can the BAB3070HS replace older Westinghouse shunt trip breakers?
Yes, this Eaton BAB breaker serves as a direct replacement for legacy Westinghouse QNBL shunt trip breakers with matching amperage and voltage requirements.
Is the BAB3070HS rated for heating and cooling equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 70A overcurrent protection device.
Do I need special lugs to use aluminum wire with the BAB3070HS?
No, the factory-installed box lugs are dual-rated for both copper and aluminum conductors ranging from 8 AWG to 1/0 AWG. Always apply a suitable oxide inhibitor when terminating aluminum wire.
How is the shunt trip wired on the BAB3070HS?
The 120VAC shunt trip mechanism features integrated pigtail leads that must be connected to your remote control circuit or emergency stop system to enable remote tripping functionality.
Can the BAB3070HS be mounted on a standard DIN rail?
No, this is a bolt-on circuit breaker designed to attach directly to the busbar of compatible Eaton and Westinghouse panelboards. It cannot be installed on a DIN rail or in plug-on load centers.

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.
