Product FAQs
8 answersWhich panelboards are compatible with the THHQB32050?
This bolt-on breaker is designed for use in GE A-Series, GE AQ, and ABB ReliaGear panelboards. It is not compatible with load centers that require plug-in style breakers.
What is the difference between the THHQB32050 and the THQB32050?
The THHQB32050 features a higher interrupting rating of 22kAIC at 240VAC. The standard THQB32050 has an interrupting rating of 10kAIC. Both share the same physical dimensions and bolt-on mounting style.
What wire sizes are accepted by the terminals on this 50A breaker?
The box lugs accept 8 AWG to 3 AWG wire for both copper (Cu) and aluminum (Al) conductors. Always verify the specific torque requirements printed on the breaker label before terminating.
Will this breaker arrive branded as ABB or General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the THHQB32050 may feature either ABB or GE branding, but the form, fit, and function remain identical.
Does the THHQB32050 include ground fault or arc fault protection?
No. This is a standard thermal magnetic breaker with fixed long-time and instantaneous (LI) trip functions. It does not provide equipment protection (EPD), GFCI, or AFCI capabilities.
Does this breaker require a specific mounting hardware kit?
The THHQB32050 bolts directly to the busbar of compatible A-Series and AQ panelboards. The mounting screws are typically retained in the breaker housing for installation, requiring no separate hardware kit.
Can I install this 3-pole breaker in a single-phase panel?
No. The THHQB32050 is a 3-pole breaker designed for 3-phase systems. It requires a 3-phase panelboard bus to mount and function correctly.
Is this breaker suitable for high-inrush loads?
The THHQB32050 uses a standard fixed thermal magnetic trip curve. For specialized high-inrush applications like large motors or transformers, verify that the standard instantaneous trip threshold meets your coordination requirements.
