QDA221001 - 100 Amp Circuit Breaker

QDA221001 - 100 Amp Circuit Breaker

The QDA221001 PowerPact Q circuit breaker is one of those components you install and don’t have to think twice about afterward—which is exactly what you want when it comes to electrical protection. Built for 240VAC systems, this 100-amp, 2-pole breaker handles everyday distribution needs with steady, predictable performance. It uses a thermal-magnetic trip mechanism, so it responds the way it should whether the issue builds over time or happens instantly. And with a 25kA interrupting rating, it’s more than capable of dealing with higher fault conditions without putting your system at risk. From an installer’s perspective, it keeps things simple. The I-Line connection helps it slot into compatible setups quickly, while the load-side lugs give you a solid, secure termination. There’s also a push-to-trip button on the front—handy for testing without needing extra steps or tools. Overall, it’s a straightforward, well-built breaker that does exactly what it’s supposed to do—protect your system and keep things running smoothly.
