Product FAQs
8 answersWhat does the HS suffix indicate on the BAB3050HS catalog number?
The HS suffix signifies that this breaker includes a factory-installed shunt trip mechanism. This allows the circuit to be opened remotely via an external control signal, distinguishing it from standard BAB3050H models.
What are common applications for the integrated shunt trip on this breaker?
The shunt trip is utilized for remote, commanded shutdown operations. Typical applications include emergency power-off (EPO) circuits, fire alarm system integrations, and automated load shedding to protect personnel and equipment.
Is this breaker a suitable replacement for legacy Westinghouse panelboards?
Yes. Eaton maintains backward compatibility across the Quicklag line, so current Eaton BAB breakers serve as direct drop-in replacements for equivalent legacy Cutler-Hammer and Westinghouse panelboards.
How does this breaker physically attach to the panelboard bus?
It utilizes an extended tang line terminal for a direct bolt-on connection to the bus. This provides a highly secure, vibration-resistant electrical joint compared to standard plug-on designs.
Are special lugs required to terminate aluminum branch circuit wiring?
No, the factory-installed box lugs on the load side are dual-rated for both copper and aluminum conductors. They accept wire sizes from 14 AWG up to 4 AWG without requiring specialized termination hardware.
Can the thermal-magnetic trip curves be adjusted in the field?
No, this breaker relies on a fixed trip element. Both the long-time thermal overload and instantaneous short-circuit protection thresholds are preset at the factory and cannot be modified.
Does the shunt trip require a separate side-mounted accessory module?
No, the BAB3050HS features an internally integrated shunt trip mechanism. This eliminates the need for panel builders to source, align, and field-install an external accessory module.
What is the relationship between the Quicklag and BAB designations?
Quicklag is the overarching family name for this line of Eaton industrial miniature breakers. BAB refers specifically to the bolt-on frame type used in Eaton Pow-R-Line panelboards.

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.
