Eaton DH364NWK Heavy Duty Fusible Safety Switch - NEMA 4X

Feature → Business Impact → Application: The DH364NWK is a three-pole, four-wire safety switch with a neutral, rated at 200 A and 600 V, enabling efficient, code-compliant motor disconnects for large industrial drives. This configuration reduces fault exposure and simplifies wiring in electromechanical systems, supporting robust motor control in manufacturing lines and packaging facilities. Application-wise, it suits heavy-duty applications up to 50 hp at 480 V and up to 150 hp at higher phases and voltages, enabling scalable control for pumps, conveyors, and fans.Feature → Business Impact → Application: The enclosure is a NEMA 4X stainless steel design (304 material), offering superior corrosion resistance and washdown suitability. This directly lowers maintenance costs and extends service life in chemical processing, food & beverage, and water treatment environments, while maintaining operator safety and enclosure integrity.Feature → Business Impact → Application: Fuse class provision is Class H with fusible elements, providing precise overcurrent protection and selective coordination. This improves lineage protection, minimizes arc-flash exposure, and reduces nuisance trips in complex motor circuits used in packaging lines and material handling systems.Feature → Business Impact → Application: The unit is UL Listed and rated for 600 V operation, delivering a clear path to compliance with electrical standards for factory automation and distribution centers. This supports fast approvals during audits and ensures compatibility with Eaton and third-party motor starters, MCCs, and switchgear.Feature → Business Impact → Application: With a compact footprint (11.63 in depth, 15.5 in width, 35.38 in height) and a weight of 61 lb, installation is straightforward in crowded control rooms or outdoor enclosures. The clarity of labeling and catalog documentation reduces commissioning time and enables easier preventive maintenance planning in uptime-critical facilities.Feature → Business Impact → Application: The product’s HP ratings and conductor sizing (#6-300 kcmil Cu/Al) provide flexibility for diverse motor loads and future expansion, enabling engineers to standardize on a single disconnect for multiple line configurations across plants. This reduces spare parts complexity and inventory costs while supporting modular plant layouts.
