THQLQ154015 - Quad 15A-40A-15A Circuit Breaker

THQLQ154015 - Quad 15A-40A-15A Circuit Breaker

The THQLQ154015 quadplex circuit breaker is a smart choice when you need to add more circuits without giving up valuable panel space. Designed for Q-Line load centers, this plug-on breaker combines two 15-amp single-pole breakers on the outside with one 40-amp double-pole breaker in the center, giving you multiple circuit functions in one compact unit. It’s commonly used in residential and light commercial electrical systems where space inside the panel is tight, but reliable protection remains a priority. The HACR rating also makes it suitable for heating and cooling equipment, helping protect HVAC circuits from overload and short-circuiting. With its molded case construction and easy plug-on installation, the THQLQ154015 offers a dependable and practical solution for panel upgrades, remodels, and replacement projects.
