Product FAQs
7 answersWhich electrical panels are compatible with the THHQB22030 circuit breaker?
This bolt-on Q-Line breaker is designed for use in GE A-Series panelboards, GE AQ lighting panels, and ABB ReliaGear panelboards. Always verify compatibility with your specific panel's labeling before installation.
What is the difference between GE THQB and THHQB circuit breakers?
Both are 1-inch wide per pole, bolt-on Q-Line circuit breakers used in commercial panels. The difference is their interrupting capacity. THQB breakers are rated at 10kAIC, while THHQB breakers have a higher interrupting rating of 22kAIC.
How does the THHQB22030 mount into the panelboard?
It features a bolt-on connection. Instead of snapping onto the bus bar like residential plug-on breakers, it physically bolts directly to the bus connections in compatible commercial load centers and lighting panels for a secure, vibration-resistant fit.
How can I tell if the THHQB22030 has tripped?
This breaker features a center trip indication. When an overload or short circuit occurs, the operating handle automatically moves to a position midway between ON and OFF, making it easy to identify a tripped circuit.
Will this breaker arrive with GE or ABB branding?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the THHQB22030 may arrive with either GE or ABB branding. The physical dimensions, specifications, and panel compatibility remain identical regardless of the label.
Can the THHQB22030 be used in 208V commercial systems?
Yes, while it is rated for 120/240V AC, it is fully compatible with 208V AC systems commonly found in commercial applications. It maintains its 22kAIC interrupting rating at this voltage.
Does this 2-pole breaker have an internal common trip?
Yes, it features an internal common trip mechanism. If an overcurrent or short circuit occurs on either pole, both poles will trip simultaneously to safely disconnect power to the entire circuit.
