Eaton / Cutler-Hammer BAB3030H Miniature Circuit Breaker

The BAB3030H is designed for use in Eaton Pow-R-Line panelboards, specifically models like the PRL1a and PRL1X. It is also compatible with legacy Cutler-Hammer, Westinghouse, Bryant, and Challenger bolt-on panelboards that accept Quicklag miniature breakers.

Yes, this 30A circuit breaker is HACR rated. This certification means it has been tested and approved to safely handle the specific inrush currents and operational demands of commercial HVACR equipment.

It features a bolt-on mounting design. The breaker physically bolts directly to the panelboard busbar using an extended tang line terminal. This provides a secure, vibration-resistant connection typically required in industrial and commercial applications.

Both are 30A, 3-pole Quicklag bolt-on circuit breakers with identical physical dimensions, but they differ in their short-circuit interrupting capacity. The BAB3030H has a 10 kAIC rating, while the QBHW3030H features a higher 22 kAIC rating at 240VAC.

Yes. Because Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines, the current Eaton BAB3030H is a direct, UL-approved drop-in replacement for legacy breakers sharing the exact same BAB catalog number.

No. While both breaker types can sometimes be installed in the same overall Eaton Pow-R-Line enclosure, BAB and GHB breakers have different frame sizes and mounting requirements. They cannot be mixed on the exact same subchassis.

No, the BAB3030H is a standard thermal-magnetic circuit breaker that provides only overload and short-circuit protection. It does not include GFCI or AFCI safety circuitry. If ground fault protection is required, a QBGF or QBHGF series breaker must be used instead.

The BAB3030H features a fixed thermal-magnetic trip unit. This means the trip thresholds for both overload and short-circuit protection are factory calibrated and cannot be adjusted or swapped out in the field.
