Eaton Specification Sheet - DH366UGKNLP
Amperage rating of 600 A enables safe interruption of large motor loads, reducing arc-flash exposure and protecting downstream equipment. This steady capability translates into shorter outage times and smoother coordination with upstream protective devices. In manufacturing lines and industrial plants, the DH366UGKNLP handles heavy conveyors, pumps, and blowers with confidence, supporting scalable control across zones. Voltage rating of 600 V supports common industrial distribution without oversized panels, while the three-pole design ensures balanced switching and minimizes neutral-related issues. This simplifies wiring in control cabinets and machine centers, reduces wiring errors during installation, and enhances overall system reliability in automated lines. NEMA 1 enclosure provides indoor protection against dust and incidental contact, enabling direct installation in switchgear rooms and protected equipment bays. Coupled with Series K compatibility, it integrates smoothly with Eaton protection devices and field wiring, reducing commissioning time and ensuring consistent mechanical alignment across installed bases. Posi-Lok positive-locks ensure secure latching, minimizing unwanted openings during vibration or maintenance checks. This improves operator confidence, reduces rework, and shortens lockout-tagout cycles in high-vibration environments like stamping presses or material-handling systems. Unfused configuration offers installation flexibility when external fusing is controlled by upstream devices or separate protection schematics. It simplifies spare parts management and enables rapid field replacement, lowering maintenance costs in high-availability applications. Durable 370 lb construction and rugged internal components support long service life in demanding environments. A one-year warranty (or eighteen months from shipment) provides predictable support, while available Eaton documentation and datasheets streamline installation planning and regulatory compliance.

FAQs
The DH366UGKNLP uses a NEMA 1 indoor enclosure suitable for factory floors, control rooms, and protected switchgear environments. Its Series K design integrates with Eaton switching devices, simplifying field wiring and mounting alignment, while the three-pole configuration supports standard three-phase motor circuits up to 600 V. This reduces installation time and ensures reliable startup.
Key ratings are 600 A and 600 V, three-pole, unfused. This means it can safely interrupt heavy motor loads without internal fusing and is designed for common industrial motor control centers. The unfused configuration supports external protection schemes, allowing integration with upstream fuses or solid-state devices while preserving quick isolation when required.
Yes. With a 600 A rating, three-pole switching, and a rugged NEMA 1 enclosure, the DH366UGKNLP is well-suited for conveyors, pump skids, and other high-demand, continuous-operation motors. Posi-Lok provides secure maintenance access, while UL Listing confirms compliance with safety standards, minimizing project risk.
The DH366UGKNLP is UL Listed, confirming compliance with established safety requirements for electrical devices. The NEMA 1 enclosure rating supports indoor general-purpose service. These certifications simplify customer audits, regulatory submissions, and plant-wide safety programs while ensuring consistent performance in standard industrial environments.
Posi-Lok provides a positive-locking mechanism that reduces accidental openings, improving reliability during maintenance. The heavy-duty construction and compatibility with Series K devices streamline installation and spare parts planning. A 1-year warranty (or 18 months from shipment) offers predictable support, while durable materials minimize service interruptions and extend equipment life in demanding facilities.
