Quad Plug-In Circuit Breaker · 15A/30A/15A Configuration · 120/240V 10 kAIC · ABB THQLQ153015
Quad plug-in thermal-magnetic breaker with a 15A/30A/15A configuration for compatible ABB and legacy GE Q-Line load centres. Used to add two 120V single-pole circuits and one 240V 2-pole circuit while saving panel space; actual suitability depends on panel labelling, circuit layout, conductor sizing, and local electrical code.
What this product is for
The ABB THQLQ153015 is a Q-Line quad plug-in circuit breaker for compatible residential and light commercial load centres. It combines two 15A single-pole circuits and one 30A double-pole circuit in a compact format to help free up panel space where the panel is listed to accept quad breakers.
Use for
- Adding two 120V 15A branch circuits and one 120/240V 30A 2-pole circuit in one breaker position set
- Service upgrades, renovations, workshops, utility circuits, and other space-limited panel work
- Compatible ABB and legacy GE Q-Line / PowerMark load centres, subject to panel directory and labelling
Avoid for
- Panels not specifically marked for tandem or quad breaker use
- Applications requiring GFCI, AFCI, or other special-function protection not provided by this breaker
- Installations where available bus position, conductor range, or interrupting rating does not match the job requirements
Best for
Best for electricians and maintenance teams who need to add circuits in a crowded Q-Line panel without installing a larger load centre. This style is commonly used when one 30A 2-pole load and two 15A 120V loads need protection in a compact footprint.
Installed in
Typically installed in compatible 120/240V ABB or legacy GE Q-Line residential load centres and meter-main/load centre combinations that are identified for these space-saving breakers. Always confirm the panel legend and breaker acceptance before ordering or installation.
Why this product exists
Quad breakers exist to increase circuit count in approved panels without adding a subpanel or replacing the load centre. As a rule of thumb, a 15A circuit is commonly paired with #14 AWG copper and a 30A circuit with #10 AWG copper, but conductor selection must follow the Canadian Electrical Code, terminal ratings, and the equipment nameplate.
Typical guidance only: continuous loads are commonly limited to 80% of breaker rating. Actual performance depends on installation conditions, load type, ambient temperature, and local electrical code.
Compared with similar products
Compared with using separate full-size breakers, this quad format helps recover panel space in approved load centres. Compared with tandem-only breakers, it also provides a factory-configured 2-pole 30A circuit for 240V loads while still adding two 15A single-pole circuits.
