ABB THQLQ203015 20/30/15A Quadplex Miniature Circuit Breaker

This breaker is designed for use in ABB ReliaHome, GE PowerMark Gold, and GE PowerMark Plus load centers. It is also compatible with legacy GE PowerMark meter socket load centers that accept Q-Line quad breakers.

This quadplex breaker fits into two standard 1-inch spaces. It provides four independent circuits, which include one 20A single-pole, one 30A double-pole, and one 15A single-pole, all within the footprint of a standard two-pole breaker.

The THQLQ203015 features two independent outer single-pole circuits rated at 20A and 15A for 120V loads, and one inner double-pole circuit rated at 30A for 240V applications.

It features fast-wiring box type lugs with combination Robertson and flathead screws. The lugs accept 14-8 AWG copper or 12-8 AWG aluminum wire.

Yes, the breaker features a three-position handle mechanism. When a fault occurs, the handle moves to a center tripped position between the ON and OFF positions for easy identification.

Yes. Following ABB acquiring GE Industrial Solutions, this breaker may be labeled under either the ABB or General Electric brand. The THQLQ203015 catalog number remains identical for both.

Standard thermal-magnetic breakers are rated for continuous loads up to 80 percent of their nominal amperage. The 15A circuit should not exceed 12A continuous, the 20A circuit 16A continuous, and the 30A circuit 24A continuous.

No. Quadplex and tandem breakers can only be installed in panel slots specifically notched and approved for them. Always check your load center wiring diagram to verify which positions accept THQLQ quad breakers.
