THQLQ203015 - Quad 20A-30A-15A Circuit Breaker

THQLQ203015 - Quad 20A-30A-15A Circuit Breaker

The THQLQ203015 quadplex circuit breaker is a space-saving, high-performance solution designed for load centers that require multiple circuits in a compact footprint. Built on the dependable THQLQ frame type, this Q-Line plug-on molded case circuit breaker combines a 2-pole 30A breaker in the center with two 1-pole breakers rated at 20A and 15A on the outside. That configuration makes it ideal for expanding circuit capacity without sacrificing valuable panel space. HACR rated for heating, air conditioning, and refrigeration applications, the THQLQ203015 delivers consistent overcurrent protection you can rely on in demanding residential and light commercial environments. Its quad design simplifies panel organization while helping contractors and facility managers maximize existing load center capacity efficiently.
