Product FAQs
8 answersCan I use the THQL1120AF2 in a GE PowerMark Gold load center?
Yes, this breaker is fully compatible with GE PowerMark Gold, GE Q-Line, and ABB ReliaHome load centers.
Is this breaker interchangeable with GE THQP types?
No. The THQL1120AF2 is a full-size 1-inch wide breaker. THQP breakers are half-inch wide and use a different mounting configuration, so they cannot be used interchangeably.
Does the THQL1120AF2 require a plug-on neutral panel?
No, this model features a standard pigtail neutral wire that connects directly to the neutral bus bar. This makes it suitable for older panels that do not support plug-on neutral breakers.
Are ABB and GE THQL1120AF2 breakers the same?
Yes. ABB acquired GE Industrial Solutions, so THQL breakers branded as ABB or General Electric are the exact same product and are fully interchangeable.
What is the difference between the THQL1120AF2 and the THQL1120PAF2?
The THQL1120AF2 uses a pigtail neutral wire for installation, while the THQL1120PAF2 is a plug-on neutral version that requires a compatible plug-on neutral load center.
What type of arc fault protection does the THQL1120AF2 provide?
This is a combination AFCI breaker. It is designed to detect and mitigate both parallel and series arcing faults to help prevent electrical fires, meeting current National Electrical Code (NEC) requirements for residential branch circuits.
Does this model replace the older THQL1120AF?
Yes, the THQL1120AF2 is the direct replacement for the discontinued THQL1120AF, offering updated combination arc fault protection.
Is this breaker rated for switching applications?
Yes, it carries SWD (Switching Duty) and HACR (Heating, Air Conditioning, and Refrigeration) ratings, meaning it can be used to switch 120V fluorescent lighting loads and protect HVAC equipment.
