What this product is for
The ABB THQB1115GF is a Q-Line bolt-on ground fault circuit breaker for 120V branch circuits requiring personnel ground-fault protection. It combines thermal-magnetic breaker protection with Class A 5 mA ground-fault protection in a 1-pole, 15A format.
Use for
- Bathrooms, kitchens, garages, outdoor receptacle circuits, and other locations where ground-fault protection is required
- ABB/legacy GE Q-Line bolt-on lighting panels and load centre applications that accept THQB format breakers
- 15A branch circuits typically wired with #14 AWG copper, subject to local code and panel listing
Avoid for
- Panels that require plug-in breakers instead of bolt-on THQB style breakers
- Applications needing AFCI or dual-function protection rather than GFCI only
- Circuits above 120V line-to-neutral where this specific ground-fault configuration is not listed for use
Best for
Best for electricians and maintenance buyers replacing or specifying a bolt-on Q-Line GFCI breaker in commercial or residential distribution equipment where panel compatibility is already confirmed.
Installed in
Installed in compatible ABB/GE Q-Line bolt-on panelboards and load centres. The breaker body is approximately 1 in wide (25 mm) per pole and uses load-side lugs for copper or aluminium conductors within the listed wire range.
Why this product exists
This breaker is used where a standard thermal-magnetic breaker is not enough and ground-fault shock protection is required at the breaker. It helps protect people from leakage current while still providing overload and short-circuit protection on the branch circuit.
Compared with similar products
Compared with a standard THQB breaker, this model adds 5 mA ground-fault protection. Compared with plug-in THQL versions, the THQB format is the bolt-on style for panelboards and other listed bolt-on applications. Always match breaker type to the panel label before ordering.
Typical guidance only: 15A branch circuits are commonly used with #14 AWG copper conductors, but actual conductor size, load, and protection requirements depend on installation conditions, equipment listing, and local electrical code.
