QBA221004 - 100 Amp Circuit Breaker Description
QBA221004 - 100 Amp Circuit Breaker
The QBA221004 PowerPact Q circuit breaker is the kind of component you install and don’t have to think about again. Built for 240VAC systems, this 100 amp, 2-pole breaker handles everyday electrical protection with steady, predictable performance. It uses a thermal-magnetic trip system, which means it responds appropriately whether you’re dealing with a gradual overload or a sudden short circuit. With a 10kA interrupting rating, it’s well-suited for common commercial and light industrial applications where reliable fault protection is a must. From an installation standpoint, it keeps things simple. The I-Line connection on the line side helps it seat quickly into compatible panelboards, while the load-side lugs give you flexibility with wiring. There’s also a push-to-trip button right on the front—useful for quick checks during routine maintenance without needing to remove anything. It’s a straightforward, well-built breaker that does what it’s supposed to do, without adding extra steps to your workflow.
