THQD22175WL - 175Amp Circuit Breaker

THQD22175WL - 175 Amp Circuit Breaker

The THQD22175WL is a 175-amp, 2-pole molded case circuit breaker designed for use in your 120/240VAC electrical distribution systems. As part of the Q-Line family, this breaker provides overcurrent protection for circuits and equipment where a higher ampacity device is required. It features an internal common trip mechanism, meaning both poles trip together when a fault condition occurs.

This breaker uses a cable-in/cable-out (lug-lug) design and comes equipped with both line-side and load-side lugs. That configuration can simplify installation in your applications where direct conductor termination is needed. With a 22,000 AIC rating at 120/240VAC, the THQD22175WL is suitable for systems where available fault current levels require a higher interrupting capacity.

The molded case construction is built for long-term service, making this breaker a practical replacement for compatible equipment already using the THQD platform. It is also HACR rated for applications involving heating, ventilation, air conditioning, and refrigeration equipment.

Where It Works Best

• The THQD22175WL is commonly found in commercial buildings, industrial facilities, HVAC equipment installations, and electrical distribution systems requiring a 175-amp, 2-pole breaker. It is often used as a form, fit, and function replacement in existing equipment designed for THQD Q-Line circuit breakers. The included lug-lug configuration also makes it well suited for applications where incoming and outgoing conductors terminate directly at the breaker.
