Description
Built for AFCI circuit protection, the General Electric THHQL1120PAF2 miniature circuit breaker is rated 20A and 120VAC with one pole. Its interrupting rating is 22kAIC at 240V. This Q-Line breaker in the THHQL series uses Plug-On mounting and a load side lug for 14-8 AWG wire. Fixed thermal and fixed magnetic trips provide long-time and instantaneous protection in a single-phase, single circuit arrangement.Specifications

Product FAQs
7 answersWhat circuit current rating should I use for the General Electric THHQL1120PAF2?
This is a 20A miniature circuit breaker. Use that rating when selecting branch-circuit overcurrent protection, and size conductors for the circuit ampacity and installation requirements.
How should I use the 22kAIC at 240V interrupting rating when selecting this breaker?
The interrupting rating is 22kAIC at 240V. Compare the interrupting rating with the available fault current at the installation point. Use the separate 120VAC voltage rating when selecting the circuit operating voltage.
What does AFCI protection do for the circuit?
AFCI protection detects arcing conditions that can create a fire hazard and trips to interrupt the circuit. Select this feature when the circuit requires arc-fault protection.
Can I adjust the thermal or magnetic trip settings?
Both thermal and magnetic trip settings are fixed. The thermal function provides long-time response to sustained overcurrent, while the magnetic function provides instantaneous response to high fault current. Select the breaker by its rating rather than planning to tune its trip settings.
What conductor sizes can I terminate on this breaker?
The wire range is 14-8 AWG, with a load-side lug for the outgoing conductor. Choose a conductor within that terminal range that also meets circuit ampacity and installation requirements; terminal acceptance alone does not determine conductor sizing.
What installation method does this breaker use?
This breaker uses plug-on mounting, with the outgoing circuit conductor terminated at the load-side lug. Plan the installation around the plug-on mounting method and the lug termination.
What do the voltage rating and pole count mean for circuit protection?
The General Electric THHQL1120PAF2 is rated 120VAC and has 1 pole. Check the circuit's operating voltage against that rating; the single pole provides overcurrent protection on one circuit conductor.
