Providing comprehensive protection against electrical fires, this 15A single-pole unit detects both parallel and series arcing faults. The included pigtail neutral facilitates straightforward wiring. Utilizing a sturdy bolt-on connection, it integrates into GE A-Series panelboards and AQ lighting panels. This updated model replaces the older THQB1115AF branch/feeder breaker. Delivering a 10kAIC interrupting rating at 120/240VAC, the device utilizes a non-interchangeable thermal-magnetic trip.Specifications

Product FAQs
5 answersCan I install the THQB1115AF2 in a standard GE residential load center?
No. The THQB1115AF2 is a bolt-on circuit breaker designed specifically for GE A-Series panelboards and AQ Lighting Panels. Standard GE residential load centers require plug-on THQL series breakers.
What does the AF2 suffix in the THQB1115AF2 catalog number indicate?
The AF2 designation indicates that this is a Combination Arc Fault Circuit Interrupter (AFCI). It provides protection against both parallel and series arc faults to meet modern National Electrical Code (NEC) requirements for branch circuits.
How is the neutral connection made on the THQB1115AF2?
This breaker features a pigtail neutral wire. During installation, the coiled white pigtail must be routed and terminated directly to the neutral bus bar in the panelboard to power the internal arc fault detection circuitry.
Does the THQB1115AF2 provide personnel ground fault (GFCI) protection?
No. This breaker is strictly a Combination AFCI device designed to detect dangerous arcing conditions that can cause electrical fires. It does not provide 5mA GFCI protection. If both arc fault and ground fault protection are required on the same circuit, a Dual Function (DFCI) breaker is necessary.
Is the THQB1115AF2 manufactured by GE or ABB?
ABB acquired GE Industrial Solutions, so this breaker may arrive branded as either ABB or General Electric. The THQB1115AF2 maintains the exact same specifications, physical footprint, and UL listing for GE panelboards regardless of the logo on the label.
