GE THQL1140 40A single-pole breaker

The GE THQL1140 is a moulded-case circuit breaker rated at 40 amps for 120/240 V AC systems. It uses a plug-in mounting style and a toggle actuator for quick installation in compatible load centres. The single-pole design protects one hot conductor in residential or light-commercial panels.

Suits panels needing a single 40 A pole

Electricians wiring a dedicated 40 A circuit in a Power Mark Gold or AQ lighting panel will find this breaker a direct fit. It is not for applications that require a two-pole breaker, DC-rated protection, or a higher interrupting rating than 10 kA. Buyers needing multiple poles or different panel compatibility should select another model.

10 kA interrupting rating at 120/240 V AC

The breaker carries a maximum AIR rating of 10 kA at 120/240 V AC, which determines whether it can safely clear a fault on the supplied circuit. Verify that the available fault current at the installation point does not exceed this value before fitting the device.

Questions about this item

How is the GE THQL1140 breaker installed in a compatible panel, and which step is often done incorrectly?

The breaker plugs into an AQ or Power Mark Gold load center; the common error is not seating it fully onto the bus stabs so the toggle feels loose.

What maintenance or replacement will the GE THQL1140 need over its service life?

No routine maintenance is required; replace the breaker if it trips repeatedly without overload, shows discoloration, or fails to reset after a fault.

What is the first limit reached when the GE THQL1140 runs continuously at high load?

The 40 A thermal trip curve opens the breaker before the 10 kA interrupting rating becomes relevant.
