THQD22150WL - 150Amp Circuit Breaker

THQD22150WL - 150 Amp Circuit Breaker

The THQD22150WL is a 150-amp, 2-pole molded case circuit breaker designed for use in your electrical distribution systems requiring dependable overcurrent protection at 120/240VAC. As part of the THQD Q-Line series, this breaker features an internal common trip mechanism that simultaneously disconnects both poles during an overload or short-circuit event, helping you to protect connected equipment and branch circuits. Built with a cable-in/cable-out (lug-lug) configuration, the THQD22150WL includes both line-side and load-side lugs, simplifying installation in compatible applications. With a 22,000 AIC interrupting rating, it is well-suited for systems where higher fault-current protection is required. Designed for long service life, this circuit breaker provides a form, fit, and functional replacement solution for compatible electrical systems.
