Eaton Specification Sheet - DH363FGKLP
The 100A amperage rating with a three-pole design enables safe switching of larger 3-phase motors up to 600V, reducing inrush damage and ensuring proper short-circuit protection for conveyors, pumps, and fans in manufacturing lines. The quick connect heavy duty construction paired with Posi-Lok provides secure, maintenance-friendly operation, enabling faster door operation and reducing downtime during routine checks or changeovers. The NEMA 1 indoor enclosure protects against dust and incidental moisture in control rooms or switchgear bays, improving equipment reliability and reducing warranty claims across plant floors. Fusible fuse configuration supports selective coordination and clear fault isolation, helping facilities meet protection standards while minimizing total cost of ownership. UL Listed certification reinforces compliance for regulated environments and streamlines audits across industrial environments.

FAQs
DH363FGKLP is designed for Series K frame compatibility, enabling straightforward replacement or upgrade within existing Eaton installations. Verify mounting pattern, enclosure size, and wiring ingress to ensure a seamless retrofit. We recommend cross-checking catalog numbers and ensuring the fusible configuration matches the system protection scheme to avoid rework during integration.
The switch supports 100A, 3-pole operation at up to 600V, with a fusible fuse configuration for protective isolation. This enables proper short-circuit protection and coordination with downstream devices. For accurate coordination, confirm fuse type, ratings, and any required accessories in the Eaton specification sheet before field installation.
Yes. With a three-pole design, 100A rating, and 600V capacity, it is well-suited for motor control in conveyors, pumps, and process lines. The NEMA 1 enclosure and Posi-Lok feature enhance reliability in indoor industrial spaces, while the UL Listed certification supports compliance during audits and inspections.
UL Listed certification confirms safety compliance for electrical products, and the NEMA 1 enclosure rating indicates indoor, dry environment suitability. Together they support regulatory adherence and reduce risk during compliance reviews. While CE or IP ratings are not listed for this model, the UL Listed status provides a clear path for many North American industrial standards.
Posi-Lok enhances mechanical retention of the switch handle, minimizing unintended opening during vibration or maintenance work and simplifying lockout-tagout procedures. This reduces unscheduled downtime and improves operator confidence. Combined with fast-installation features and UL-listed safety, facilities can realize lower maintenance costs and faster return-on-investment in control panels.
