Eaton DH368FRKV Heavy Duty Fusible Safety Switch - UL Listed

1200 A amperage rating and 600 V capability enable true main power isolation for large motors and feeders. This high-capacity specification reduces the number of components required and simplifies protection strategy, lowering install time and spare parts inventory. Ideal for heavy-load panels in stamping presses, plastic and metal fabrication lines, and large conveyors that demand reliable isolation. Three-pole, three-wire configuration with fusible without neutral and Class L fuse provision simplify wiring and align with standard industrial practices. The result is faster commissioning, improved fault clarity, and safer energy isolation during maintenance windows. This design supports standard protection schemes while accommodating popular fuse types used across industries. NEMA 3R enclosure and painted galvanized steel deliver weather-resistant protection for indoor and moderately outdoor environments. Enhanced visible blades improve operator confidence and reduce inspection time during routine checks. The enclosure’s mechanical robustness translates to longer service life in harsh environments. Heavy-duty footprint and the 72 in length, 21 in height, and 48 in width with an approximate 455 lb weight underscore its fixed-mount suitability in centralized power distribution. The HDSS catalog notes reinforce its use in demanding systems, supporting reliable operation with minimal field adjustments. Installation benefits include stable mounting and predictable electrical clearance. UL Listed certification, NEC barrier compliance, and compliance with industrial safety standards help meet regulatory requirements and customer audits. This combination of certifications supports risk mitigation and easier vendor qualification. When paired with Eaton accessories and HDSS families, maintenance teams can streamline spares and service planning.
