Eaton double door single-throw fused safety switch DD327NWKW-00V2 - UL Listed

Feature: Rugged enclosure and corrosion resistance. The DD327NWKW-00V2 employs a NEMA 4X, 304 stainless steel enclosure for reliable protection against moisture, dust, and washdown environments. This durability reduces maintenance and replacement costs in outdoor substations, coastal facilities, or challenging factories, while preserving fast access for routine inspections. Business Impact: Longer service life and lower lifecycle costs support uptime in harsh environments. Application: Outdoor substations, coastal facilities, and washdown areas benefit from corrosion-resistant construction. Feature: High-current, multi-pole protection. Rated 800 A at 240 V with three poles and four wires, this fused switch uses Class L protection and a load-side voltage indicator, ensuring safe, controlled disconnection of large motors up to 500 hp (3PH @480/600 V). The design supports tight interlocks and rapid fault isolation for significant uptime gains. Business Impact: Enhanced motor protection reduces nuisance tripping and unplanned downtime. Application: Heavy-duty motors and large feeders in manufacturing and process plants. Feature: Load-side voltage indicator with window. The built-in indicator on the load side, visible through a window, enables quick status checks during startup and maintenance without opening the enclosure, reducing unplanned downtime and operator errors in critical applications. Business Impact: Faster commissioning and safer maintenance routines. Application: System startups, routine inspections, and fault diagnosis. Feature: Flexible wiring and installation. Accepts large conductors—from #1/0 up to 750 kcmil—accommodating heavy feeders and future expansion. With a three-pole, four-wire configuration and a compact footprint (approximately 86.73 in long, 22.16 in high, 26.57 in wide, 300 lb), installation aligns with standard switchgear layouts and simplifies retrofits. Business Impact: Streamlined wiring and retrofit compatibility reduce installation time and project risk. Application: Upgrades and new installations in industrial facilities with demanding feeder requirements. Feature: Certifications, warranty, and support. UL Listed with Eaton’s 25-000 warranty policy (one year from installation or 18 months from shipment). The combination of 304 stainless steel, Class L fuse provisions, and line-isolation capability provides regulatory compliance and predictable maintenance costs, backed by Eaton’s engineering support and readily available spares. Business Impact: Clear regulatory compliance and predictable maintenance budgeting. Application: Facilities seeking proven protection with vendor-backed support.
