Schneider Electric QMB-363-T Panelboard Fusible Switch

Schneider Electric's QMB363T is a 100 A, 600 V fusible panelboard switch in a 3‑pole configuration, designed to serve as a primary disconnect with fused protection in panelboard installations. The main switch is factory-mounted on the bus assembly and cannot back-feed a branch switch, while the unit provides a solid neutral that may be bonded to the enclosure with a grounding strap. Rated for up to 15 HP motor loads at 600 VAC, this compact device aligns with the QMB fusible panelboards family in a roughly 7.5‑inch footprint. Discontinued on June 12, 2024, Schneider Electric indicates that the QMB363T has not been replaced by a direct successor.
