QDA222251 - 225 Amp Circuit Breaker

QDA222251 - 225 Amp Circuit Breaker

When you’re working with electrical systems, reliability isn’t optional—it’s expected. The QDA222251 PowerPacT Q circuit breaker is designed to handle everyday demands without fuss, providing solid overcurrent protection for 240VAC distribution systems. With a 225-amp, 2-pole configuration and thermal-magnetic trip unit, it responds quickly to overloads and short circuits, helping protect your equipment before problems escalate. What makes this breaker especially practical is how it fits into real-world setups. The I-Line connection on the line side makes installation straightforward in compatible panelboards, while the mechanical lugs on the load side offer flexibility during wiring. There’s also a built-in push-to-trip button, so testing the breaker during maintenance is quick and simple—no guesswork involved. Backed by a 25kA interrupting rating, it’s built to handle demanding conditions without overcomplicating things.
