Product FAQs
6 answersWhat is the difference between the THQB2115 and a THQL circuit breaker?
The THQB2115 is a bolt-on breaker designed for commercial panelboards, securing directly to the busbar with screws. THQL breakers are plug-in style units meant for residential load centers. They are not interchangeable.
Which panelboards accept the THQB2115 breaker?
This breaker fits General Electric A-Series panelboards and GE AQ Lighting Panels. Because it is a bolt-on unit, it will not fit standard GE plug-in load centers.
Is this 15-amp Q-Line breaker HACR rated?
Yes, the THQB2115 is UL listed for Heating, Air Conditioning, and Refrigeration (HACR) motor loads and equipment applications.
Will this breaker arrive with GE or ABB branding?
ABB acquired GE Industrial Solutions in 2018, so newly manufactured units may carry the ABB brand. They are the exact same OEM parts, built to the original Q-Line specifications, and are fully backward compatible with older GE panels.
How does a bolt-on connection benefit this breaker installation?
Screwing the breaker directly to the panel busbar provides a rigid mechanical connection. This prevents the breaker from vibrating loose over time, making it ideal for commercial or industrial environments.
What does the LI trip function mean?
LI stands for Long-Time and Instantaneous. It indicates the breaker utilizes a thermal-magnetic trip unit to provide thermal protection against prolonged overloads (Long-Time) and magnetic protection to instantly clear sudden short circuits (Instantaneous).
