ABB THHQL1130GFT2 1 Pole Ground Fault Circuit Breaker
The ABB THHQL1130GFT2 is a 1 Pole thermal magnetic molded case ground fault circuit breaker with a current rating of 30 Amps and a voltage rating of 120VAC. It has an interrupting rating of 22kAIC.
What load centers are compatible with the ABB THHQL1130GFT2 circuit breaker?
This Q-Line plug-in breaker is designed for use in ABB and legacy GE ReliaHome, PowerMark Gold, and PowerMark Plus load centers that accept 1-inch THQL or THHQL series breakers.
Does the THHQL1130GFT2 require a plug-on neutral panel?
No, this model features a standard pigtail neutral wire. It can be installed in traditional load centers that do not have a plug-on neutral bus.
What level of ground fault protection does the THHQL1130GFT2 provide?
It provides Class A Ground Fault Circuit Interrupter (GFCI) protection with a 5mA trip threshold, designed to protect personnel from electrical shock.
Does this GFCI breaker include an automatic self-test function?
Yes, the GFT2 suffix indicates that this breaker includes a self-test feature to continuously verify that the ground fault circuitry is functioning properly.
How much panel space is required to install the THHQL1130GFT2?
As a 1-pole Q-Line breaker, it requires a single 1-inch space in the panel.
How is the neutral wired on this pigtail GFCI breaker?
The breaker's coiled white pigtail wire must be connected to the panel's neutral bus bar, while the dedicated load neutral wire connects directly to the neutral terminal on the breaker.
Can the ABB THHQL1130GFT2 replace a legacy GE THHQL1130GFT2?
Yes. Following ABB's acquisition of GE Industrial Solutions, the ABB THHQL1130GFT2 is the direct, exact replacement for the legacy GE-branded THHQL1130GFT2.
Is the THHQL1130GFT2 suitable for standard 10kAIC residential panels?
Yes. Its 22kAIC interrupting rating exceeds standard 10kAIC requirements, making it fully suitable for those applications while offering a higher fault current withstand rating.
