Eaton Specification Sheet - DH327NGKLPR
Feature → Business Impact → Application: 800A amperage rating enables safe, reliable switching for large motors and feeders, reducing the risk of nuisance trips and unplanned downtime in manufacturing lines. Use this in high-load feeders to improve overall equipment effectiveness (OEE) and protect downstream equipment. Feature → Business Impact → Application: Three-pole configuration with fusible switch and solid neutral provides precise fault isolation and predictable protection, minimizing arc exposure and simplifying motor starter coordination in 240V networks. Ideal for process lines, conveyors, and machine control panels where dependable protection is essential. Feature → Business Impact → Application: Posi-Lok reverse pin enhances interlock reliability and ease of installation maintenance, reducing field adjustments and misalignment during panel assembly in retrofit projects. Pair with standard control schemes for safer, faster commissioning in industrial facilities. Feature → Business Impact → Application: NEMA 1 indoor enclosure supports dust and basic environmental protection, enabling straightforward integration into electrical rooms and equipment bays without special outdoor housing. Suitable for plant floors with controlled environments and where indoor protection is mandated. Feature → Business Impact → Application: Series K compatibility ensures seamless procurement and replacement within Eaton’s family of safety switches, reducing spare parts inventory and accelerating maintenance cycles in multi-vendor or retrofit programs. Application across automotive, food & beverage, and general manufacturing environments benefits from consistent Eaton interfaces and documented performance.

FAQs
Installers should plan for a three‑pole, 240V feed with appropriate feeder conductors sized for 800A, and ensure the panel has a compatible mounting footprint for the DH327NGKLPR. Verify NEMA 1 indoor enclosure suitability, secure Posi-Lok reverse pin alignment during assembly, and follow Eaton’s catalog sheet for torque specs and wiring diagrams to minimize commissioning time.
The 800A rating supports large motor starts and feeder protection without frequent tripping, allowing designers to select appropriate overcurrent protection and contactor sizing that match load profiles. This reduces nuisance trips, improves startup reliability, and lowers energy losses during peak demands while maintaining safe shutdown capabilities.
No. The DH327NGKLPR uses a NEMA 1 enclosure designed for indoor installations and dust protection. For outdoor or damp environments, you would need an enclosure rated for those conditions or an additional weatherproof housing, and you should evaluate climate-related derating and corrosion considerations in your design.
Yes. Eaton provides a product specification sheet for the DH327NGKLPR, plus catalogs and safety resources. The specification sheet outlines electrical data, wiring diagrams, and installation guidance to facilitate integration with existing switchgear and control schemes. For more, consult the Eaton datasheet linked in the product downloads section.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, schedule periodic inspections of mechanical interlocks, check Posi-Lok pins for wear, verify fuse integrity, and confirm enclosure seals remain intact to preserve safety and reliability over the device’s life.
