THHQL Series 20A Breaker
This GE THHQL2120 miniature circuit breaker provides 20 amp protection for single-phase 120/240V AC circuits. It is designed for electricians and facility managers installing or maintaining compatible load centres.
22kA Interrupting Capacity
The high interrupting capacity rating of 22kA at 120/240V AC handles substantial fault currents safely. It is not suited for DC applications or systems requiring a higher AIR rating than specified.
Plug-In Mounting with Screw Clamps
The plug-in mounting style fits AQ series panelboards and Power Mark Gold load centres for straightforward installation. Screw clamp terminals secure conductors reliably. The frame measures 3.3 in length by 2 in width for standard panel spacing.

Questions about this item
Will the THHQL2120 fit alongside older single-pole breakers in my Power Mark Gold load center?
Yes, the THHQL2120 is a 2-pole plug-in breaker designed for Power Mark Gold and AQ lighting panels, so it occupies two adjacent slots next to any existing single-pole units.
How can I verify the 22kA interrupting rating is active after installation?
With the toggle in the ON position and load applied, the breaker will trip only on overcurrent; the 22kA AIR rating at 120/240V AC is a design specification confirmed by the THHQL series marking on the label.
Does the box include mounting screws or terminal lugs for the screw-clamp connections?
The breaker ships as a complete plug-in unit with integral screw-clamp terminals; no separate lugs or mounting hardware are required for Power Mark Gold or AQ panel installation.
