THQLQ153015 - Quad 15A-30A-15A Circuit Breaker

THQLQ153015 - Quad 15A-30A-15A Circuit Breaker

The THQLQ153015 quadplex molded case circuit breaker is designed to help you maximize panel space while delivering dependable branch circuit protection in residential and light commercial electrical systems. Built with a convenient plug-on Q-Line configuration, this quad breaker combines two 15-amp single-pole breakers on the outside with a 30-amp double-pole breaker in the center, making it a smart choice for applications where panel capacity is limited but multiple circuits are required. Its HACR rating also makes it suitable for heating, air conditioning, and refrigeration equipment applications.

Compact yet highly functional, the THQLQ153015 is engineered for reliable overcurrent and short-circuit protection while simplifying installation in compatible load centers. The quadplex configuration allows electricians and maintenance professionals to add additional circuits without expanding panel footprint, helping you to save both time and space during upgrades, remodels, or replacement projects. Whether you're supporting HVAC equipment, general lighting circuits, or small appliance loads, this breaker offers practical versatility for demanding electrical environments.
