Product FAQs
5 answersIs the ABB THQB1115 the same as the GE THQB1115?
Yes. ABB acquired GE Industrial Solutions in 2018. Both brands share the identical internal design, footprint, and THQB1115 catalog number. An ABB branded breaker is a direct, manufacturer-approved replacement for an older GE branded unit.
What is the difference between GE THQB, THQL, and THQC circuit breakers?
All three belong to the 1-inch wide Q-Line family but utilize different panel mounting methods. The THQB series mounts via a bolt-on connection to the bus. THQL breakers are plug-on units, and THQC breakers feature cable-in, cable-out lug connections or surface mounting.
Can the THQB1115 be reverse fed?
Yes, this fixed thermal magnetic circuit breaker does not have line or load terminal restrictions and is rated as suitable for reverse feed applications.
Is the THQB1115 suitable for switching lighting circuits?
Yes, this 15-amp breaker carries an SWD (Switching Duty) classification. It is approved for the regular daily switching of 120VAC fluorescent lighting loads without rapidly degrading the internal contacts.
Does this breaker carry an HACR rating?
Yes, the THQB1115 is HACR rated. It is certified for use with compatible heating, air conditioning, and refrigeration motor groups that require this specialized branch circuit protection.
