Product FAQs
8 answersWhich panelboards are compatible with the GB2030 circuit breaker?
The GB2030 is designed for use in Eaton, Cutler-Hammer, and Westinghouse Series C panelboards, as well as Pow-R-Line panelboards.
Is the Eaton GB2030 suitable for reverse feed applications?
Yes, all Eaton G-frame circuit breakers, including the GB2030, are suitable for reverse feed use.
Is the GB2030 HACR rated?
Yes, this G-frame breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
Why is this breaker listed under Eaton, Cutler-Hammer, and Westinghouse?
Eaton acquired the Westinghouse distribution equipment business and integrated it with Cutler-Hammer. The GB2030 is the exact same G-frame breaker regardless of which of these three brands is printed on the label.
What is the difference between the GB2030 and the GHB2030?
Both are 30-amp, 2-pole G-frame bolt-on breakers, but they have different maximum voltage ratings. The GB2030 is rated for 240VAC maximum, while the GHB2030 is rated for up to 480Y/277VAC.
How does the GB2030 connect to the panelboard bus?
It is a bolt-on circuit breaker that fastens directly to the panelboard bus bars using screws. This provides a secure mechanical and electrical connection that resists vibration better than plug-on alternatives.
Are the trip settings on the GB2030 adjustable?
No, the GB2030 features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions.
What does the 65kAIC rating on the GB2030 indicate?
It means the breaker can safely interrupt up to 65,000 amps of fault current at 240VAC without sustaining internal damage. This high interrupting capacity is common in commercial and industrial panelboards.
