Quad Circuit Breaker · 2 x 20A 1-Pole + 1 x 15A 2-Pole · 120/240V Plug-In 2 in Space-Saving Design · ABB THQLQ201520
Quad plug-in thermal-magnetic breaker for ABB/GE Q-Line load centres, combining two 20A single-pole circuits and one 15A double-pole circuit in a 2 in (51 mm) format. Commonly used to add 120/240V branch circuits where panel space is limited; confirm the panel label and breaker acceptance before ordering.
What this product is for
The THQLQ201520 is a Q-Line plug-in quad circuit breaker used to add multiple branch circuits in one 2 in (51 mm) breaker space. It combines two 20A single-pole circuits and one 15A double-pole circuit for 120/240V applications in compatible ABB and legacy GE load centres.
Use for
- Adding circuits in residential load centres where breaker space is limited.
- Supplying two 120V 20A circuits plus one 240V 15A 2-pole circuit in a compact layout.
- Panel retrofits, renovations, garages, workshops and light commercial branch circuit additions where the panel is listed to accept quad breakers.
Avoid for
- Panels not specifically labelled for ABB/GE Q-Line plug-in breakers.
- Applications requiring a higher interrupting rating than 10 kAIC.
- Installations where a full-size 2-pole breaker or different pole arrangement is required.
Best for
Best for electricians and maintenance buyers who need to free up panel capacity without changing the load centre. This format is commonly selected when adding a small 240V load alongside two 120V circuits in existing Q-Line panels.
Installed in
Designed for compatible ABB Q-Line and legacy GE Q-Line/PowerMark load centres that are listed to accept this breaker type. Always verify the panel directory and acceptance markings before installation.
Why this product exists
Quad breakers help solve panel space constraints by fitting more protected circuits into fewer spaces. For service work, this can be a practical alternative to a panel change when the existing load centre is in good condition and approved for quad breaker use.
Typical guidance only: quad breakers are commonly used to recover panel capacity during renovations or equipment additions. Actual suitability depends on panel listing, load calculation, conductor sizing, installation conditions and local electrical code.
Compared with similar products
Compared with a tandem breaker, this quad configuration adds both single-pole circuits and a common-trip 2-pole circuit in the same 2 in (51 mm) footprint. Compared with using separate full-size breakers, it saves panel space, but compatibility is more panel-specific and should be checked carefully.
