Product FAQs
5 answersWhat is the difference between BAB, QBHW, and HBAX circuit breakers?
All three are Eaton Quicklag bolt-on breakers that share the same physical footprint and fit the same panels. The difference is their interrupting capacity. BAB breakers are rated at 10kAIC, QBHW breakers are rated at 22kAIC, and HBAX breakers are rated at 65kAIC at 120/240VAC.
Can I use a QBHW1050 to replace a standard BAB1050 breaker?
Yes, the QBHW1050 can directly replace a BAB1050. It shares the exact same Quicklag BAB frame and bolt-on mounting, but provides a higher 22kAIC interrupting rating for systems with higher available fault current.
Which panelboards are compatible with the QBHW1050?
This bolt-on breaker is designed for use in Eaton Pow-R-Line panelboards, including the Pow-R-Line 1a, 2a, and 3a series distribution panels that accept Quicklag bolt-on breakers.
Is the QBHW1050 HACR rated?
Yes, Eaton Quicklag bolt-on breakers from 15A to 100A, including the 50A QBHW1050, are HACR rated for safe use with heating, air conditioning, and refrigeration equipment.
Can the QBHW1050 be used in DC electrical systems?
Yes, this breaker is rated for DC applications up to 48VDC with an interrupting capacity of 5kAIC.
