Description
Part of the Q-Line family, this single-pole 15A breaker provides 30mA ground fault equipment protection (GFEP) for dedicated machinery and heat-tracing circuits. The 30mA threshold is specifically calibrated to protect equipment from electrical damage without the nuisance tripping associated with 5mA personnel GFCIs. Built with a cable-in/cable-out lug design, it mounts easily onto DIN rails or within GE Q-Line enclosures. It carries a 10kAIC rating at 120V and is SWD rated.Specifications

Product FAQs
6 answersWhat type of panels or enclosures accept the THQC1115GFEP breaker?
This breaker is designed for GE Q-Line enclosures, OEM panels, and control panels. It features a cable-in/cable-out lug design and can be mounted directly onto standard 35mm DIN rails.
Can I use the THQC1115GFEP in a standard GE residential load center?
No. Standard GE residential load centers typically require plug-on THQL or THQP breakers. The THQC series uses a feed-thru connection and DIN rail mounting, making it suitable for OEM and control panels rather than standard residential load centers.
What is the difference between this GFEP breaker and a standard GFCI breaker?
This Ground Fault Equipment Protection (GFEP) breaker has a 30mA trip threshold designed to protect machinery and heat tracing circuits from electrical damage. Standard GFCI breakers have a 5mA trip threshold intended for personnel protection.
How do I connect the neutral on this breaker?
The THQC1115GFEP features a pigtail neutral wire that must be connected directly to the neutral bus bar in your panel or enclosure to ensure proper ground fault detection.
How much space does this breaker require on a DIN rail?
The THQC1115GFEP is a 1-inch wide per pole breaker, requiring 1 inch of space on a standard 35mm DIN rail.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, Q-Line breakers like the THQC series are now manufactured and branded under ABB while maintaining exact compatibility with legacy GE installations.

- POPaul O.Verified BuyerReviewingABB / General Electric THQC2150 - 50A 2 Pole Molded Case Circuit BreakerI recommend this productRated 4 out of 5 stars9/3/26Recent Breaker Purchases
These breakers matched perfectly for my main AC supplies for my boat. I had the original 43-year-old Chinese (GenFu) breakers that failed and these GEs were a perfect match. My only reservation for not providing a 5-star review is breakers do not arrive in GE's original packaging which can lead to questions whether they are truly "new" breakers. Otherewise, happy I found some that replaced my originals. Thanks SB!
