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

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

When panel space starts running out, this is the kind of breaker that solves the problem without forcing a bigger upgrade. The THQLQ203015 quadplex circuit breaker is built to give you more flexibility in a tight footprint, combining multiple circuits into one compact unit. Instead of juggling separate breakers, you get a 2-pole breaker in the center and two 1-pole breakers on the outside, all in a single plug-on design. It’s part of the Q-Line family, so it’s made to fit right into compatible load centers and install without hassle. The 20/30/15 amp configuration makes it especially useful when you’re dealing with mixed loads—like pairing HVAC equipment with general circuits. And since it’s HACR rated, it’s ready for heating and cooling applications where dependable protection matters. This is a practical, no-nonsense choice for electricians and property owners who need to do more with the space they already have.
