THQD32225WL - 225Amp Circuit Breaker

THQD32225WL - 225 Amp Circuit Breaker

The THQD32225WL is a 225-amp, 3-pole, molded-case circuit breaker designed for dependable overcurrent protection in your commercial, industrial, and institutional electrical distribution systems. Part of the widely used THQD Q-Line family, this breaker features an internal common trip mechanism that simultaneously disconnects all poles when an overcurrent or fault condition is detected, helping you to protect connected equipment and electrical infrastructure.

Built in a cable-in/cable-out (lug-lug) configuration, the THQD32225WL includes both line-side and load-side lugs, simplifying installation and replacement in compatible electrical systems. With a 22kA interrupting capacity at 240VAC, this breaker is engineered to interrupt fault currents within its rated capacity while maintaining safe circuit protection. Its HACR rating also makes it suitable for applications involving heating, air conditioning, and refrigeration equipment that require code-compliant circuit protection.

Constructed for long-term service, the THQD32225WL provides a form, fit, and functional solution for maintaining existing electrical distribution equipment that utilizes THQD-series circuit breakers.
