THQD32225 - 225Amp Circuit Breaker

THQD32225 - 225 Amp Circuit Breaker

The THQD32225 is a 225-amp, 3-pole molded case circuit breaker designed for use in your commercial, industrial, and institutional electrical distribution systems requiring dependable overcurrent and short-circuit protection. As part of the THQD Q-Line series, this bolt-on circuit breaker features an internal common trip mechanism that simultaneously disconnects all three poles when an overcurrent condition occurs, helping you protect connected equipment and branch circuits from electrical faults. Built for applications operating at up to 240VAC with a 22kA interrupting capacity, the THQD32225 is engineered to provide reliable circuit protection while maintaining compatibility with designated Q-Line panelboards and distribution equipment. The included load-side lugs help you to simplify installation, while the molded case construction is designed to withstand the demands of everyday electrical service. With its HACR rating, this breaker is also suitable for applications involving heating, air conditioning, and refrigeration equipment where code-compliant overcurrent protection is required. Designed with long service life in mind, the THQD32225 provides a form, fit, and functional replacement solution for compatible electrical systems requiring a 225A, 3-pole bolt-on circuit breaker.
