Product Identity

The GE THQL1120AF2 is a 20A single-pole arc-fault circuit interrupter rated for 120/240V AC systems. It is designed for residential and light-commercial panels that require arc-fault protection on individual branch circuits.

Panel Compatibility

This breaker plugs into GE Power Mark Gold load centres and AQ lighting panels rated up to 100A frame size. Its interrupting rating is 10kA at 120/240V AC; it does not carry a DC voltage rating and must not be applied to DC circuits.

Installation Checklist

Verify the panel is a compatible AQ or Power Mark Gold series and that a single-pole space is available. Confirm the branch circuit requires 20A arc-fault protection and that the supply voltage is 120/240V AC. Ensure the screw-clamp terminals suit the conductor size being used.

Questions about this item

Should I choose the 20 A single-pole version or a different amperage for my lighting panel?

Select the 20 A single-pole breaker when the circuit is wired for 20 amps; the THQL frame also offers other amp ratings that fit the same AQ or Power Mark Gold panel.

What does the 10 kAIC rating mean once the breaker is installed in my load center?

It means the device can safely interrupt up to 10 000 amps of fault current at 120/240 V AC without damage.

The plug-in mounting fits which panel interface, and what does that limit?

The plug-in design mates with GE AQ lighting panels and Power Mark Gold load centers; it will not seat in panels that use a different bus-stab layout.
