Product FAQs
8 answersWhat does the "WL" suffix indicate in the THHQC21100WL catalog number?
The "WL" suffix means the breaker includes factory-installed wire lugs on both the line and load sides. These box lugs accommodate 6 to 1/0 AWG copper or 4 to 1/0 AWG aluminum conductors.
How is the THHQC21100WL mounted in a panel?
Unlike standard plug-in or bolt-on breakers, this THHQC unit features a feed-thru design. It is designed to mount on a standard 35mm DIN rail or directly within OEM panels and control enclosures.
Can I use the THHQC21100WL in a standard GE residential load center?
No. Standard GE residential load centers require THQL plug-in breakers. The THHQC series is a lug-to-lug, DIN rail mountable breaker intended for OEM equipment, control panels, and specific enclosures.
Why might my THHQC21100WL arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions. As a result, Q-Line breakers like the THHQC21100WL may be branded as either ABB or GE. The physical dimensions, mounting, and electrical specifications remain identical regardless of the label.
Does this breaker provide ground fault or arc fault protection?
No. The THHQC21100WL is a standard thermal magnetic circuit breaker providing long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not include GFCI or AFCI circuitry.
What is the difference between THQC and THHQC breakers?
The extra "H" in the THHQC prefix indicates a higher interrupting capacity. While standard THQC breakers are rated for 10kAIC, the THHQC series is rated for 22kAIC at 120/240V AC.
Is the THHQC21100WL suitable for reverse feeding?
Yes. This breaker is suitable for reverse feed applications, allowing power to be supplied to either the line or load terminals.
Is the THHQC21100WL HACR rated?
Yes. This breaker carries an HACR rating, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
