Quad Plug-In Circuit Breaker · 15A 1P + 15A 2P + 15A 1P · 120/240V Q-Line · ABB THQLQ151515
ABB THQLQ151515 is a Q-Line quad plug-in thermal-magnetic breaker rated 15A with one 2-pole 15A circuit and two 1-pole 15A circuits in two panel spaces. It is commonly used to add branch circuits in compatible ABB and GE by ABB PowerMark load centres where space is limited; always confirm panel compatibility and circuit layout before ordering.
What this product is for
This quad plug-in circuit breaker provides overload and short-circuit protection while fitting three 15A branch circuits into two standard panel spaces. It is designed for compatible single-phase ABB and GE by ABB PowerMark load centres using Q-Line plug-in breakers.
Use for
Use it when you need one 15A 2-pole circuit plus two 15A 1-pole circuits without expanding the load centre. Typical applications include residential renovations, basement circuits, garage or workshop additions, and service work where panel space is limited.
Avoid for
Avoid using it in panels not specifically listed for THQLQ quad breakers, in positions not approved by the panel directory, or where a different breaker type is required. Do not use it as a substitute for verifying bus stab layout, panel labelling, or local code requirements.
Best for
Best for electricians and contractors working on ABB or legacy GE residential distribution equipment who need to recover panel capacity without changing the load centre. It is especially useful where a standard 1 in (25 mm) breaker footprint per pole arrangement would otherwise consume more space.
Installed in
Installed in compatible 120/240V or 120/208V single-phase load centres. This breaker occupies two standard spaces and is intended for ABB and GE by ABB PowerMark load centres, including newer and existing single-phase models identified by the manufacturer as compatible.
Why this product exists
This product exists to increase usable circuit count in crowded panels while maintaining a listed plug-in solution. Compared with using separate full-size breakers, a quad breaker can free space for future work or help complete an addition without replacing the panel.
Typical guidance only: on 15A branch circuits, electricians commonly pair these with #14 AWG copper conductors where permitted by code and application. Actual conductor selection, derating, and breaker use depend on installation conditions, equipment labelling, and local electrical code.
Compared with similar products
Compared with a tandem breaker, this quad configuration gives you two 1-pole circuits plus one common-trip 2-pole circuit in the same two-space footprint. Compared with installing separate breakers, it can reduce panel congestion, but only where the load centre is listed to accept quad breakers in that location.
