Eaton Specification Sheet - DH227NGKLP
Feature: 800A amperage rating with a two-pole configuration. This capability delivers robust isolation for high-current equipment, improves protection coordination across feeders, reduces arc-flash exposure during fault events, and supports safe coordination with upstream protection devices. Application: ideal for large motor loads, production lines, and primary feeders in manufacturing facilities where a reliable, fast disconnect is essential for uptime and worker safety. Feature: Fusible with solid neutral. This arrangement supports straightforward fuse coordination, predictable fault paths, and enhanced shutdown reliability under overload conditions. It also simplifies wiring schemes by providing a common neutral reference, reducing wiring errors and maintenance confusion. Application: well-suited for heavy-duty circuits requiring a solid neutral return, including high-power drives and line-side protections in complex power distribution panels. Feature: Series K construction with a rugged NEMA 1 enclosure. The combination delivers durable indoor protection against dust and debris, minimizes environmental risk, and eases routine maintenance with accessible wiring and high-reliability components. It also aligns with Eaton's product families for streamlined spare parts, service planning, and cross-compatibility across protection devices. Application: commonly deployed on plant floors and electrical rooms in dry environments to support critical processes while maintaining service continuity. Feature: Posi-Lok mechanism for secure actuation. This advanced latching feature prevents unintended operation in vibration-heavy environments, reduces control-system misoperation, and delivers consistent switch position signaling essential for automation reliability. Application: essential for conveyors, presses, automated lines, and material-handling systems where reliability and repeatability of isolation events drive productivity and safety. Feature: Quick-connect wiring capability. This design accelerates field wiring, reduces commissioning time, and lowers labor costs by simplifying harness routing and terminal connections. It also improves installer ergonomics and minimizes the risk of improper terminations during installation. Application: especially valuable to panel builders and technicians integrating large-scale protection into switchgear and distribution panels, shortening project timelines. Feature: UL Listed certification and Eaton warranty. Certification ensures compliance with recognized safety standards while the warranty delivers post-sale support under policy 25-000, covering one year from installation or eighteen months from shipment, whichever occurs first. Application: beneficial for procurement, compliance audits, and risk management across plant operations, enabling budget planning for replacements and maintenance with confidence.
