Matching GE Breaker Frames to the Panel
Every item on this page files in the circuit breaker collection, and every one of them either fits a specific panel or it does not, because the panel label decides. This page sorts the 160 GE items by frame family so you can match the label first and pick amperage second.
Which GE Breaker Line You Need
Q-Line Plug-In: THQL, THQP, and THQMV
THQL is the standard one-inch-per-pole plug-in breaker for GE loadcenters, stocked here in 1, 2, and 3 pole versions from 15A to 125A. THQMV main breakers extend the frame to 125A, 150A, and 200A. THHQL versions raise the interrupt rating to 22kA, and options include GFT ground fault, GFEP equipment-level ground fault, AF2 arc fault, and PDF dual function plug-on neutral models.
THQP is the half-inch space saver version of the same line, stocked from 15A to 50A. Manufacturer listings pair these families with GE PowerMark and ABB ReliaHome panels, and the load center collection is where the panel side of that pairing lives, though it currently stocks other manufacturers' panels.
Q-Line Bolt-On: THQB and THQC
THQB is the bolt-on version of the Q-Line for loadcenters and lighting panels that bolt to the bus, stocked 15A to 100A in 1, 2, and 3 pole versions. THHQB models raise the rating to 22kA, and ST1 versions add a 120V shunt trip. THQC models with the WL suffix extend the bolt-on range, and GFT and GFEP protection versions mirror the plug-in side.
TEY, TED, and Spectra Molded Case
TEY breakers are bolt-on units for 277/480V lighting panels, stocked 15A to 100A at a 14kA interrupt rating, with TEYL versions rated 65kA. TED E-frame breakers cover 480V distribution duty. The Spectra series carries the heavy end: SELA, SFHA, and SGHA frames from 30A to 400A at 600V, set by SRPE, SRPF, and SRPG rating plugs from 15A to 600A, some with adjustable instantaneous trip. TQD frames add 150A and 200A units, and TCAL lug kits, mounting hardware, handle locks and ties, filler plates, and a TE150R NEMA 3R enclosure complete the frames.
Reading GE Breaker Numbers
The letters name the family and mounting, the first digit after the letters is the pole count, and the final digits are the amperage. THQL1120 is a 1 pole 20A plug-in, THQB2150 is a 2 pole 50A bolt-on, and THQL32100 is a 3 pole 100A plug-in. Suffixes carry the protection: GFT ground fault trip, GFEP ground fault equipment protection, AF2 arc fault, ST1 shunt trip, and PDF the plug-on neutral dual function models.
GE, ABB, and the Cross Reference Question
ABB acquired GE Industrial Solutions in 2018, and the breaker lines continued under the same part numbers, so a THQL2120 ordered today is the current production of the same catalog number in the panel, whether the box reads GE, ABB, or GE by ABB. That continuity is why cross referencing a GE panel rarely means leaving the GE number at all.
What the ABB deal did not change is interchange: breakers are not interchangeable across manufacturers unless the panel label lists them. When the panel on site is a BR or CH series, price the replacement from the Eaton collection instead.
Older panels wearing the Westinghouse-era name are covered through the Cutler Hammer collection, which maps those legacy numbers to current production.
QO and Homeline labels route to the Square D collection and its own frame logic.
QP era labels route to the Siemens collection, where the same panel-label rule applies.
Confirming a GE Breaker Match
Work the label in this order. Panel compatibility first, since the label lists the exact breaker types the bus accepts, and thin THQP breakers are only permitted where the label says so. Then amperage and pole count against the circuit, then the interrupt rating, kAIC, the fault current in thousands of amps the breaker can safely clear. This range spans 10kA standard, 14kA on TEY, 22kA on THHQ models, and 65kA on TEYL. Then voltage class, 120/240V for Q-Line against 277/480V for TEY and 600V for Spectra, then any code-required protection such as GFCI, AFCI, or dual function, and finally plug-in against bolt-on mounting.
GE Breaker Cross Reference Questions
Are GE breakers still made after the ABB acquisition?
Yes. ABB acquired GE Industrial Solutions in 2018 and continues producing the breaker lines under the same catalog numbers, with packaging that may read GE, ABB, or GE by ABB. The number on the panel schedule is still the number to order.
What is the difference between THQL and THQB?
Mounting. THQL is the plug-in version that stabs onto the bus of a GE loadcenter, while THQB is the bolt-on version that fastens to the bus with a screw, common in commercial lighting panels. Ratings overlap heavily, so the panel construction decides which one you buy.
Can THQP thin breakers go in any GE panel?
No. THQP models are half-inch-per-pole space savers, and they are only permitted in panels whose label explicitly allows thin or tandem breakers, and only in the positions the label marks. Installing them elsewhere violates the listing, so check the panel door before ordering them to add circuits.
What do GFT, GFEP, and AF2 mean on a GE number?
They are the protection packages. GFT is personnel-level ground fault protection, GFEP is equipment-level ground fault protection at a higher trip threshold, and AF2 is arc fault protection. PDF models combine ground and arc fault in one plug-on neutral breaker for dwelling circuits that require both.
What is a rating plug on a Spectra breaker?
Spectra frames such as SE150 separate the frame from its ampere rating, and the SRPE, SRPF, or SRPG rating plug sets the rating, 15A through 600A here, with some plugs adding adjustable instantaneous trip. That lets one installed frame change rating by swapping the plug instead of the breaker.
