THQLQ203020 - Quad 20A-30A-20A Circuit Breaker

THQLQ203020 - Quad 20A-30A-20A Circuit Breaker

The THQLQ203020 quad circuit breaker is a good option when you need to add more circuits but don’t have much room left in the panel. It combines two 20-amp single-pole breakers with one 30-amp double-pole breaker in a single compact unit, helping free up space while keeping the panel organized. The plug-on design makes installation straightforward, and the breaker is commonly used in residential and light commercial electrical systems where reliability and space savings both matter.

This breaker is part of the Q-Line series and is HACR-rated, making it suitable for heating and cooling equipment as well as general branch-circuit protection. Its molded case design helps protect against overloads and short circuits during normal operation. Contractors often use quadplex breakers like the THQLQ203020 for panel upgrades, remodels, and applications where adding circuits without replacing the entire panel can save time and labor.
