Schneider Electric H322NRB Fusible Heavy Duty Safety Disconnect Switch

Schneider Electric’s Square D H322NRB Fusible Heavy Duty Safety Disconnect Switch is a rugged, three-pole disconnect designed to safely isolate power to 60 A, 240 V, three‑phase loads in industrial installations. Housed in a 3R-rated enclosure, it is suitable for outdoor or demanding environments where reliable isolation is required and is designed to accept H-class fuses to provide fast-acting protection for motors, pumps, conveyors, and other high-current equipment. As a fusible safety switch, the H322NRB serves as a dedicated disconnect point, enabling maintenance personnel to de-energize circuits without removing the power supply from upstream protection, while keeping fuse elements readily replaceable. The unit’s three-pole configuration supports standard 240 V three-phase systems and provides a straightforward, code-compliant means of isolation at the equipment level. This model is part of Schneider Electric’s Square D safety switches family, delivering dependable performance in harsh industrial environments and compatibility with Schneider’s H-series fuse kits for integrated, field-upgradable protection of connected equipment.
