Eaton DH268NGK heavy duty fusible safety switch - UL Listed
Part Number: DH268NGK
Quick Summary
The Eaton DH268NGK heavy duty fusible safety switch provides safe isolation for 1200 A, 600 V industrial systems. It helps reduce downtime and risk during maintenance by delivering reliable, code-compliant isolation and clear fault indication. Key certifications include UL Listed, NEC 230.62 (C) compliant barrier, and a NEMA 1 enclosure, reinforcing compliance in harsh environments. In practice, this means easier procurement, faster installation, and safer, scalable protection for heavy-duty switchgear. Designed for two-pole, three-wire configurations, it supports large conductor sizes (4/0 to 750 kcmil Al) for rapid integration with existing feeders. The enclosure's painted steel construction and Class L fuse provisions help meet installation safety standards and long-term reliability in industrial environments.

Feature: 1200 A amperage rating and 600 V voltage rating provide robust protection for high-current feeders. Business impact: This capacity reduces the risk of nuisance tripping and arc-flash exposure by enabling proper fusing at the source. Application: Ideal for main feeders in manufacturing lines, heavy machinery, and power distribution panels where reliability is critical. Feature: Fusible with neutral and Class L fuse construction enable selective coordination and safe fault clearing. Business impact: Improves downtime metrics by preventing unnecessary trips and preserving downstream protection. Application: Suitable for disconnecting heavy loads with reliable current-limiting that maintains system stability. Feature: NEMA 1 enclosure with painted steel provides indoor protection against dust and incidental moisture. Business impact: Enhances longevity and reduces maintenance costs in harsh industrial environments while meeting enclosure requirements. Application: Fits indoor switchgear rooms, service panels, and control cabinets where neat installation matters. Feature: UL Listed and NEC 230.62 (C) compliant barrier ensure regulatory alignment and safer operation. Business impact: Streamlines procurement and reduces risk during audits by aligning with recognized standards. Application: Common in facilities requiring formal safety certification, including manufacturing and data centers. Feature: Supports large conductor sizes (4/0 to 750 kcmil aluminum) enabling direct integration with existing feeders. Business impact: Minimizes the need for rewiring or adapters, cutting installation time and material costs. Application: Suitable for high-capacity distribution feeders in industrial plants. Feature: Two-pole, three-wire configuration with neutral and rated for 600 V offers straightforward installation and reliable isolation. Business impact: Improves safety during maintenance and lockout-tagout procedures while ensuring consistent performance. Application: Ideal for control panels and safety switch gear in manufacturing and process facilities.

FAQs
Verify the two-pole, three-wire configuration and ensure conductor sizes fall within 4/0 to 750 kcmil aluminum. Confirm the NEMA 1 indoor footprint fits the panel cutout and provide proper clearance for the fusible links. Follow Eaton installation instructions and coordinate with upstream protection to maintain selective coordination.
The high rating enables protection of large feeders and motors while allowing upstream protection to coordinate efficiently. Select fuses to match motor starting currents to minimize nuisance trips, and ensure conductor sizing supports the load. This results in improved uptime and safer fault clearance for heavy-duty applications.
Yes. The DH268NGK features a NEC 230.62 (C) compliant barrier and a UL Listed designation, along with a NEMA 1 indoor enclosure, aligning with typical compliance requirements for indoor service disconnects and control panels.
UL Listed DH268NGK provides verified safety, reliability, and performance in high-current applications. The fusible with neutral design supports safe disconnection and selective coordination, reducing arc flash risk and maintenance downtime while meeting recognized standards and providing essential installation documentation.
The unit carries a one-year warranty from installation or 18 months from shipment. Regularly inspect the painted steel enclosure for corrosion, verify neutral connections, and replace fusible elements per Class L specifications. Maintain proper lockout/tagout procedures and reference Eaton documentation for audits and ongoing protection.
