The Cutler Hammer QBHW3060HT is a 3 Pole thermal magnetic molded case circuit breaker with a current rating of 60 Amps and a voltage rating of 240VAC. It has an interrupting rating of 22kAIC at 240V. The QBHW3060HT has a bolt-on connection type and includes long time and instantaneous trip functions.
What does the HT suffix indicate on the QBHW3060HT part number?
The HT suffix designates that this breaker is equipped with terminals designed to accept ring or spade lugs, providing a secure wire connection for industrial applications.
Which Eaton panelboards are compatible with the QBHW3060HT circuit breaker?
This bolt-on breaker is compatible with Eaton and Cutler Hammer Pow-R-Line panelboards, specifically the PRL1a, PRL2a, PRL1X, and PRL2X series that accept BAB and QBHW frame types.
Can I install this QBHW breaker in an older Westinghouse panelboard?
Yes, QBHW series breakers are backward compatible with many legacy Westinghouse panelboards, such as the W22B series, that are designed to accept bolt-on BAB or QBHW frame breakers.
What is the difference between the BAB and QBHW frame types?
While they share the same physical footprint and panelboard compatibility, BAB breakers are rated for a 10kAIC interrupting capacity, whereas QBHW breakers are rated for a higher 22kAIC interrupting capacity.
Is the QBHW3060HT rated for HVAC applications?
Yes, Eaton Quicklag breakers in this amperage range are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.
Why choose a bolt-on connection over a plug-on breaker?
Bolt-on breakers like the QBHW3060HT secure directly to the panelboard busbar using screws. This provides a highly reliable, mechanically secure connection that prevents the breaker from loosening in environments with heavy vibration.
