THQLT2020 - 20A-20A Duplex Circuit Breaker

THQLT2020  -  20A-20A Duplex Circuit Breaker

The THQLT2020 duplex circuit breaker is a smart way to add two 20-amp circuits without taking up two full spaces in your panel. Built on the THQLT frame and designed for Q-Line load centers, this plug-on breaker gives you dependable overcurrent protection in a compact format. With a 10kA interrupting rating at 120VAC, it’s made to handle typical residential and light commercial fault conditions while helping protect wiring and connected equipment from overloads and short circuits. Because it’s a duplex (20/20 amp) configuration, you get two independent single-pole breakers in the footprint of one. That makes it especially useful when panel space is tight but you still need additional branch circuits. It’s also HACR rated, so it’s suitable for heating and air conditioning applications where code compliance matters. If you’re replacing an existing breaker or expanding a panel without upgrading the entire load center, the THQLT2020 offers a straightforward, reliable solution that installs quickly and fits as expected.
