Description
Part of GE's Q-Line family, this 30A GFCI breaker provides critical 5mA ground fault protection for 120V circuits. It mounts into GE A-Series panelboards and AQ lighting panels using a reliable bolt-on connection. The THQB1130GF utilizes a thermal-magnetic trip mechanism with a 10 kAIC rating and features a quick-make/quick-break design. As a legacy component, it is frequently used to maintain existing systems before upgrading to the newer THQB1130GFT self-testing model.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the THQB1130GF circuit breaker?
This bolt-on breaker is designed specifically for GE A-Series panelboards and GE AQ lighting panels. It cannot be installed in standard residential plug-on load centers.
How is the neutral connection wired on the THQB1130GF?
This breaker utilizes a pigtail neutral. The coiled white pigtail wire must be connected directly to the neutral bus bar in the panelboard for the ground fault circuitry to function correctly.
What is the ground fault trip threshold for the THQB1130GF?
This breaker provides Class A ground fault protection. It is calibrated to trip when it detects a ground fault leakage current of 5mA, protecting personnel from electrical shock.
Can I substitute a Siemens or Eaton bolt-on breaker for the THQB1130GF?
No. The National Electrical Code requires breakers to be listed for the specific panel. Only GE THQB breakers are UL listed for GE A-Series and AQ panels.
Can I use the THQB1130GF to replace a THQL breaker?
No. The THQB series features a bolt-on connection for commercial panels, while the THQL series uses a plug-on connection for residential load centers. They are not interchangeable.
What does the LIG trip function code indicate on this breaker?
The LIG code signifies that the thermal magnetic trip unit includes Long-Time overload protection, Instantaneous short-circuit protection, and Ground-Fault protection.
