Product FAQs
7 answersWhich panelboards are compatible with the BAB3030HS breaker?
This bolt-on breaker mounts exclusively into Eaton Pow-R-Line, legacy Westinghouse, and Bryant panelboards designed for Quicklag BAB type breakers. It cannot be used in residential plug-on load centers like the Eaton BR or CH series.
How many panel spaces does the BAB3030HS require?
Although it is a 3-pole breaker, the factory-installed shunt trip requires one extra pole space on the right side. You will need a total of four pole spaces in your panelboard to install this unit.
What does the HS suffix in the BAB3030HS catalog number indicate?
The HS suffix designates a factory-installed shunt trip module. This feature allows the breaker to be tripped remotely by applying an external control voltage, which is commonly used for emergency stops or fire alarm control panels.
How do you wire the shunt trip module on this Quicklag breaker?
The shunt trip includes non-polarity-sensitive wire leads. You must connect one lead to your control voltage source and route the other lead through a normally open contact, such as a momentary pushbutton or alarm relay, to complete the tripping circuit.
Can I use this Eaton breaker to replace an older Cutler-Hammer BAB3030HS?
Yes. Eaton and Cutler-Hammer are the same brand. The current Eaton BAB3030HS is the direct, manufacturer-approved replacement for the legacy Cutler-Hammer version and features the exact same form factor and specifications.
Is the BAB3030HS HACR rated for HVAC equipment?
Yes, this circuit breaker is HACR rated. It is fully approved for protecting heating, air conditioning, and refrigeration circuits that require HACR-certified overcurrent protection.
Does the shunt trip module provide ground fault or arc fault protection?
No. The shunt trip is strictly designed for remote manual tripping or interfacing with external control systems. It does not provide integral GFCI or AFCI safety protection.

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.
