FAQs
For proper installation, mount the HDSS in a suitable enclosure with adequate clearance for three-pole, 240 V operation. Use the 72 inch depth, 21 inch height, and 48 inch width footprint as a guide for panel integration. Ensure bar-coded labeling aligns with NEC requirements and verify conductor sizes (up to four 750 kcmil aluminum per the catalog) are accommodated by the switch-fuse configuration.
The DH328FDKV is UL Listed and designed to meet NEC 230.62 barrier requirements, providing a compliant isolation point for branch-circuit distribution. Its NEMA 12/3R enclosure offers appropriate environmental protection, while the Class L fuse provision supports safe, selective protection in industrial power systems.
The switch is rated for 1200A at 240V in a three-pole, fusible configuration (without neutral). It uses a NEMA 12/3R enclosure with a 72 in product length/depth, 21 in height, and 48 in width, and weighs approximately 455 lb. These specs fit large industrial panels and motor-control centers requiring rugged protection.
Yes. The catalog supports conductors from four #1/0 to four 750 kcmil aluminum (Al), enabling flexible power distribution for high-current applications. This accommodates significant motor and drive wiring while preserving safe, code-compliant terminations.
The unit combines a painted galvanized steel enclosure, a durable HDSS platform, and an enhanced visible blade for quick status checks. These features simplify field inspections, reduce maintenance time, and improve safety during shutdowns, while UL Listed status and NEC barrier compliance support procurement and audit readiness in regulated industries.
