Eaton / Cutler-Hammer QBHW1020 Miniature Circuit Breaker

This breaker is designed for Eaton and Cutler-Hammer Pow-R-Line panelboards. It physically fits into PRL1a, PRL2a, PRL3a, and PRL4a series panels.

Both are 20A, 1-pole Quicklag bolt-on breakers with identical physical dimensions. The only difference is their short-circuit interrupting rating. The BAB1020 is rated for 10kAIC, while the QBHW1020 provides a higher 22kAIC rating for systems with higher fault current potentials.

Yes. This breaker is SWD rated, meaning it is approved for switching 120V fluorescent lighting loads on and off. It is also HACR rated for safe use with commercial heating, air conditioning, and refrigeration equipment.

As part of the Quicklag series, it uses a bolt-on mounting mechanism. The breaker must be mechanically bolted directly to the panelboard bus, which provides a highly secure connection that resists loosening in commercial or high-vibration environments.

Yes. Because Eaton acquired the Westinghouse and Cutler-Hammer electrical distribution divisions, this current-production breaker is physically identical to legacy Westinghouse BAB or QBHW models. It serves as a direct drop-in replacement for those older units.

No. This is a standard thermal-magnetic circuit breaker that provides long-time and instantaneous trip functions for basic overload and short-circuit protection. It does not contain AFCI or GFCI circuitry.
