QDA221752 - 175 Amp Circuit Breaker Description
QDA221752 - 175 Amp Circuit Breaker
If you’re looking for a circuit breaker that combines reliability with straightforward performance, the QDA221752 PowerPacT Q circuit breaker is a solid choice for keeping your electrical systems protected and running without interruption. Designed for 240VAC applications, this 175-amp, 2-pole breaker delivers dependable overcurrent protection using proven thermal-magnetic trip technology. That means it responds quickly to both overloads and short circuits—helping prevent costly damage and downtime. Its I-Line connection on the line side makes installation faster and more secure in compatible panelboards, while the mechanical lugs on the load side give you flexibility during setup. Add in a strong 25kA interrupting rating and a built-in push-to-trip button for easy testing, and you’ve got a breaker that’s built to perform when it matters most.
