- 100 A two-pole protection for 120/240 V AC panels
- 10 kA interrupting rating handles heavy fault currents
- Bolt-on mounting fits GE load centres directly
- UL Listed for code-compliant residential and light-commercial use
- Accepts 6 AWG to 1/0 AWG conductors for flexible wiring
GE THQB 100 A Double-Pole Breaker
The GE THQB breaker is a bolt-on miniature circuit breaker rated at 100 amps for 120/240 V AC single-phase panels. It provides standard overcurrent protection for lighting and load-centre applications with a 10 kA interrupting rating at the rated voltage. The toggle actuator gives clear on/off indication and the lug terminals accept conductors from 6 AWG up to 1/0 AWG.
Ideal for Panel Builders and Electricians
This breaker suits installers fitting a 100 A two-pole device into a compatible GE load centre or lighting panel where bolt-on mounting is required. It is not intended for DC circuits, three-phase systems or panels that accept only plug-on breakers, and it cannot serve applications needing a higher interrupting rating or a different frame size.
10 kA AC Interrupting Rating
The maximum AIR rating of 10 kA at 120/240 V AC determines whether the breaker can safely clear a fault in the target installation. Verify that the available fault current at the panel does not exceed this value before specifying the device.

Questions about this item
Does the THQB21100 come with the lug terminals or do I need to buy them separately?
The breaker includes a terminal connection lug for wire sizes from 6 AWG to 1/0 AWG, so no separate lug purchase is required.
Should I choose the 100 A two-pole version or a different amp rating for a 120/240 V panel?
Select the 100 A two-pole model when the circuit requires 100 A protection on a 120/240 V AC single-phase panel; other amp ratings protect different load levels.
What does the 10 kA interrupting rating mean when the breaker is installed in a load center?
It means the breaker can safely interrupt up to 10 kA of fault current at 120/240 V AC, protecting the panel and downstream wiring during a short circuit.
