Product FAQs
7 answersHow does the THQP120 differ from a standard THQL1120 breaker?
The THQP120 is a half-inch wide slim circuit breaker. A standard THQL1120 breaker requires a full 1-inch space per pole. Using a half-inch THQP breaker allows you to fit more circuits into a compatible load center.
Will the THQP120 fit any slot in a GE load center?
No. It must be installed in a GE Q-Line or PowerMark Gold load center specifically designed to accept half-inch THQP breakers. Check your panel label to confirm compatibility before installation.
Is the GE THQP120 suitable for HVAC equipment?
Yes. This circuit breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific safety designation.
Can I use this breaker to switch fluorescent lighting?
Yes. This 20-amp single-pole breaker carries an SWD rating, meaning it is certified for switching duty on 120V fluorescent lighting circuits.
Can I use this GE THQP120 in place of a UBITB120 breaker?
Yes. The GE THQP120 is the exact original equipment manufacturer equivalent and can replace the aftermarket Connecticut Electric UBITB120 circuit breaker.
Can I install this breaker in a Siemens or Murray panel?
No. The THQP120 is only UL listed for installation in compatible ABB and GE enclosures. Installing it in other brands violates electrical codes and voids the panel listing.
Can I use two THQP120 breakers for a 240V circuit?
No. Two single-pole breakers lack the internal common trip mechanism required for 240V loads. You must use a dedicated two-pole breaker, such as the THQP220, to ensure both ungrounded conductors trip simultaneously during a fault.
