Description
Manufactured by ABB under the Thomas & Betts brand, the GFB130 is a 1-pole, 30A GFCI circuit breaker for residential and commercial use. This plug-on unit installs into Thomas & Betts TB series load centers. For legacy maintenance, it is commonly replaced by Eaton's GFTCB130 or BRN130GF models when updating older enclosures. Operating at 120VAC with a 10kAIC rating, it provides 5mA Class A ground-fault protection and includes a pigtail neutral for NEC compliance.Specifications

Product FAQs
6 answersWhich load centers are compatible with the Thomas & Betts GFB130 breaker?
The GFB130 is designed for use in Thomas & Betts load centers and TB Series panels. Because Thomas & Betts panels were manufactured by General Electric, this breaker is part of the Q-Line family and fits standard 1-inch plug-on spaces.
What is the General Electric equivalent for the Thomas & Betts GFB130?
Because GE manufactured Thomas & Betts load centers, the GFB130 is a direct equivalent to the GE THQL1130GF. Both are 30A, 1-pole, Q-Line GFCI breakers.
Does the GFB130 require bolt-on hardware for installation?
No, the GFB130 features a plug-on mounting style. It snaps directly into the bus bar of compatible Thomas & Betts or GE Q-Line load centers without the need for mounting screws or bolts.
How does the GFB130 connect to the panel neutral?
This breaker features a pigtail neutral connection. The coiled white wire must be connected directly to the neutral bus bar in the panel to ensure the ground fault circuitry functions properly.
What type of trip functions are included in the GFB130?
The GFB130 utilizes a thermal magnetic trip mechanism with an LIG function code. This provides long-time and instantaneous overcurrent protection, along with ground fault protection to prevent electrical shocks.
Can the GFB130 be used in systems with an available fault current higher than 10,000 amps?
No, the GFB130 has a maximum interrupting rating of 10kAIC at 120V AC. It must not be installed in systems where the available fault current exceeds this rating.
