Product FAQs
5 answersAre ABB and GE THQL circuit breakers the same?
Yes. ABB acquired GE Industrial Solutions, so ABB ReliaHome and GE PowerMark Gold Q-Line breakers are identical and fully interchangeable. You may receive stock branded as either ABB or GE.
What is the difference between THQL and THQP breakers?
THQL breakers are full-size Q-Line breakers taking up 1 inch of space per pole. THQP breakers are half-size and require only 1/2-inch per pole. They mount differently and are not interchangeable. Your load center must specifically accept full-size THQL breakers to use this model.
Is the THQL2120 rated for HVAC equipment?
Yes. This breaker carries an HACR rating, meaning it has been tested and approved for use with heating, air conditioning, and refrigeration equipment motor loads.
Does this breaker provide arc-fault or ground-fault protection?
No. The THQL2120 is a standard thermal-magnetic breaker that provides traditional overload and short-circuit protection. It does not include AFCI or GFCI circuitry.
Does the THQL2120 require a pigtail or neutral connection?
No. Because this is a standard thermal-magnetic circuit breaker without GFCI or AFCI features, it does not require a neutral wire connection to the panel busbar.
