Eaton DH365NPKLW Heavy Duty Fusible Safety Switch - UL

Feature → Business Impact → Application: The 400 A amperage and 600 V rating deliver robust protection for large motor feeders, reducing fault exposure and enabling reliable start‑up in heavy machinery environments. This supports equipment uptime and longer motor life in packaging, metal fabrication, and process lines, where high surge events are common. Feature → Application → Benefit: Three-pole, four-wire configuration with fusible switch and neutral simplifies wiring, improves fault isolation, and reduces panel clutter, making retrofit projects and new builds faster to Commission while meeting NEC requirements. Feature → Benefit → Application: NEMA 4 painted steel enclosure provides indoor and outdoor protection against dust, water ingress, and corrosion, extending service life in exterior switchgear cabinets and wash-down environments often found in chemical and Food & Beverage facilities. Feature → Benefit → Application: Class H fuse provision and fusible with neutral offer precise selectivity and improved melt characteristics, lowering arc energy and minimizing downstream damage in fault events, ideal for critical conveyor and processing lines. Feature → Benefit → Application: Cable conditioning and conductor sizing guidance (up to 2/0 Cu to 750 kcmil Al/Cu) supports exact installation planning, reducing cable waste and facilitating compliant terminations in power distribution assemblies. Feature → Benefit → Application: The 11.2 in depth, 22.66 in width, and 57.47 in height footprint with a 125 lb weight enable predictable enclosure planning for panel upgrades, ensuring compatibility with existing rack layouts in motor control centers and switchgear rooms. Feature → Benefit → Application: UL Listed status and NEC barrier compliance combined with a 600 V rating provide confidence during audits and in regulated industries, supporting fast procurement, reduced risk, and consistent performance across multiple lines.
