Schneider Electric QO3301021 Shunt Trip Push In Circuit Breaker

Schneider Electric QO3301021 is a three‑pole, 30 A miniature circuit breaker designed for 120/240 V AC systems with a 10 kA interrupt rating and plug‑in mounting in the QO series panels. This unit includes an integrated AC shunt‑trip accessory for remote disconnection from a separate control circuit, enabling fast safety shutdown when triggered by external safety or fire‑alarm systems. Built for standard QO load centers and panelboards, it provides reliable overcurrent protection on three‑phase circuits up to 30 A per pole and is suitable for commercial and light industrial distribution where remote trip capability is required.
