Schneider Electric H363 Fusible Disconnect Switch

Schneider Electric's Square D H363 heavy-duty fusible safety switch is a 100-amp, three-pole disconnect designed for 600 V systems, delivering reliable isolation for industrial equipment such as motors, VFDs, and control circuits across demanding manufacturing environments where reliability matters. This three-phase, three-wire device uses fusible protection and comes in a NEMA 1 indoor enclosure, making it suitable as either a service disconnect or an equipment isolation switch where compliance and safety are critical. The H363 family is compatible with H, J, K, L, and R fuse classes (class H/J/K/L/R fuses), providing flexible protection options for feeders, transformers, and motor circuits, with a visible-fuse indicator window for quick status checks. As part of Square D's H-series heavy-duty safety switches in Series F, the H363 is UL-listed and built with a rugged metal enclosure to withstand industrial settings, offering robust performance when fast, safe disconnection is required.
