Product FAQs
8 answersDoes the THHQC2140WL mount directly to a DIN rail?
It can be mounted to a standard 35mm DIN rail using compatible adapters, or it can be surface-mounted in an enclosure. It does not snap directly onto a DIN rail without the proper adapter hardware.
What does the WL suffix indicate on the THHQC2140WL?
The WL suffix indicates that this Q-Line breaker is a lug-lug version. It has box lugs on both the line and load sides, making it suitable for feed-thru applications rather than plugging or bolting onto a busbar.
Is the THHQC2140WL compatible with standard GE residential load centers?
No, this is a unit-mount, feed-thru breaker with lugs on both ends. It is designed for OEM panels, control enclosures, and DIN rail applications, not for plugging into standard residential load center busbars.
What are the physical dimensions of the THHQC2140WL?
This Q-Line breaker is one inch wide per pole, making the total width 2 inches. It has a depth of 2.38 inches and a height of 3.28 inches.
How does this breaker indicate that it has tripped?
The THHQC2140WL features a visual trip indicator where the toggle handle moves to a center position when a fault occurs, allowing for quick identification in a panel.
Does this 2-pole breaker have an internal common trip?
Yes, it features an internal common trip bar that ensures both poles trip simultaneously in the event of an overload or short circuit on either leg, preventing single-phasing.

It utilizes a quick-make, quick-break toggle mechanism that ensures fast and reliable switching action, reducing arcing and extending the life of the contacts.
