Eaton / Cutler-Hammer BAB3050H Miniature Circuit Breaker

This bolt-on circuit breaker is designed for Eaton Pow-R-Line 1a, 2a, 1X, and 2X panelboards. It also mounts directly into legacy Westinghouse, Cutler-Hammer, and Bryant panelboards that accept standard Quicklag bolt-on breakers.

Both are 3-pole 50-amp bolt-on breakers with identical physical footprints for Pow-R-Line panelboards. The BAB series is rated at 10kAIC at 240VAC, whereas the QBHW series provides a higher interrupting rating of 22kAIC.

It features an extended tang line terminal that bolts directly to the panelboard bus. Fastening typically requires standard 10-32 x 0.56 inch hex head branch feeder mounting screws.

In the Eaton Quicklag nomenclature, the H suffix denotes 240VAC construction specific to two-pole and three-pole configurations.

No. This is a bolt-on miniature circuit breaker intended strictly for commercial and industrial panelboards, such as the Eaton Pow-R-Line series. Residential load centers typically require plug-on breakers like the Type BR or CH.

No. While 15-amp and 20-amp single-pole BAB breakers carry a Switching Duty (SWD) rating for fluorescent lighting, the 50-amp 3-pole BAB3050H does not. It should not be used as a primary physical switch for lighting loads.

The box lugs are approved for use with 60-degree C or 75-degree C rated copper or aluminum conductors. Ensure your wire sizing follows National Electrical Code guidelines for a 50-amp branch circuit.

Yes. Eaton Quicklag BAB circuit breakers between 15 amps and 100 amps are HACR rated. This makes the 50-amp BAB3050H suitable and legally compliant for protecting heating, air conditioning, and refrigeration equipment.
