QBA221002 - 100 Amp Circuit Breaker

QBA221002 - 100 Amp Circuit Breaker

The QBA221002 PowerPacT Q circuit breaker is a solid, no-nonsense option for protecting 240V electrical systems. Rated at 100 amps with a 2-pole design, it’s commonly used in commercial and light industrial setups where consistent performance matters. At its core, this breaker uses a thermal-magnetic trip system, which means it reacts to both overloads and short circuits. In practical terms, that helps prevent damage to wiring and equipment before problems escalate. It’s the kind of protection you want in place so you’re not dealing with unexpected shutdowns later. Installation is straightforward if you’re working with I-Line panelboards. The line side uses an I-Line connection, while the load side is equipped with mechanical lugs that accommodate a wide range of wire sizes. There’s also a built-in push-to-trip button, which makes it easy to test the breaker during routine maintenance without any extra steps. This model also carries a 10kA interrupting rating, giving it the ability to safely handle fault conditions in typical 240V applications. For anyone working with HVAC systems, it’s worth noting that this breaker is HACR rated, so it’s suitable for heating and cooling equipment as well.
