Quad plug-in thermal-magnetic circuit breaker rated 20/40/20A at 120/240V AC, combining two 20A single-pole circuits and one 40A double-pole circuit in a 2 in panel space. Commonly used to add mixed 120V and 240V branch circuits in compatible ABB or legacy GE Q-Line load centres where panel space is limited.

What this product is for

This ABB Q-Line quad circuit breaker provides branch-circuit protection for two 20A 120V circuits and one 40A 240V circuit in one compact device. It is a plug-in thermal-magnetic breaker for compatible ABB and legacy GE Q-Line load centres.

Use for

Use it when you need to add circuits without expanding the panel, such as adding two 20A general-purpose circuits plus one 40A 240V load. Typical applications include workshop equipment, small HVAC or appliance loads, and mixed residential branch circuits where the panel is listed to accept quad breakers.

Avoid for

Avoid using this breaker in panels not specifically identified for ABB or GE Q-Line quad breakers. Do not use it where the panel labelling, bus arrangement, or circuit position restrictions do not permit tandem or quad devices.

Best for

Best for electricians and contractors working on service upgrades, renovations, and panel reconfigurations where available breaker space is tight. It is especially useful when one 240V load and two 120V loads must be added in a single 2 in (51 mm) breaker space.

Installed in

Installed in compatible ABB and legacy GE Q-Line load centres and panelboards that are listed for this breaker type. Always confirm the panel directory and manufacturer labelling before installation.

Why this product exists

This breaker exists to increase circuit capacity within limited panel space while maintaining standard branch-circuit protection. As a rule of thumb, 20A circuits are commonly paired with #12 AWG copper conductors, while a 40A circuit is typically matched to conductor sizing based on the connected load and applicable code. Actual conductor and breaker selection must follow the Canadian Electrical Code, equipment nameplate data, and local authority requirements.

Compared with similar products

Compared with a standard full-size 2-pole breaker plus two separate 1-pole breakers, this quad breaker saves panel space by combining all three circuits into one assembly. It is a better fit when the load centre accepts quad breakers and circuit count is the main constraint.
