GE THQB32090 Circuit Breaker 90A 3 Pole 240V AC 10kA
Three-pole 90 A breaker rated 240 V AC with 10 kA interrupting capacity, bolt-on mounting for lighting panels and load centres
- 90 A rating protects heavy three-phase loads
- 10 kA interrupting capacity clears faults safely
- Bolt-on mounting fits GE THQ load centres
- 120/240 V AC rating suits standard panels
- UL Listed for code-compliant installations
THQB 90 A Three-Pole Breaker
The GE THQB32090 is a bolt-on miniature circuit breaker rated at 90 A with three poles for 120/240 V AC systems. It carries a 10 kA interrupting rating at that voltage and fits THQB load centres and lighting panels. The frame size is 100 A, and lug terminals accept conductors from 6 AWG to 1/0 AWG.
Suited For Three-Phase Panel Builds
This breaker suits electricians wiring three-phase lighting panels or load centres that require a 90 A standard-trip device with bolt-on mounting. It is not for DC circuits, single-pole applications, or installations needing a higher interrupting rating than 10 kA at 240 V AC.
90 A Continuous With 10 kA Interrupting
The device handles 90 A continuous loads within a 100 A frame, providing headroom for typical lighting and receptacle circuits. It runs out when the available fault current exceeds 10 kA at 240 V AC or when the connected load demands more than the 90 A rating and 1/0 AWG maximum conductor size.

Questions about this item
What panel or load-center frame size is required to mount this 3-pole bolt-on breaker?
The breaker is designed for a 100 A frame size THQ panel or load center with bolt-on mounting rails.
Will the 90 A, 240 V AC rating coordinate with existing 10 kA-rated branch breakers in the same panel?
Yes, the 10 kA AIR rating at 120/240 V AC matches typical 10 kA branch devices, so coordination follows standard panel design rules.
How can I verify the breaker trips correctly after wiring it with 6 AWG to 1/0 AWG conductors?
Turn the toggle to ON, apply load, then press the toggle to the tripped position; it should move to the middle trip position and reset cleanly when switched OFF then ON.
