Eaton Specification Sheet - DH366FGKLPR
Three-pole, 600A, 600V fusible design in Series K provides dependable isolation under heavy load. This reduces arc flash risk and fault propagation, cutting unplanned downtime and improving overall equipment reliability. It is ideal for motor feeders and line start-ups on assembly lines where predictable current limiting and safe shutdown sequences are essential. The NEMA 1 indoor enclosure and compact footprint (11.13 in W x 21.69 in H x 9.89 in D) support tight installations and simpler retrofits, minimizing cabinet rework and speeding up panel commissioning. Posi-Lok reverse pin delivers secure handle positioning, preventing accidental opening in high-vibration environments and ensuring correct sequencing during maintenance. UL Listed certification confirms compliance with electrical safety standards, while the 600V rating and three-pole configuration support proper overcurrent protection coordination across plant infrastructure. The unit’s 22 lb weight and rugged mechanicals enable longer service intervals, with a one-year warranty (or 18 months from shipment) aligning with typical procurement and maintenance cycles for OEMs and industrial plants.

FAQs
DH366FGKLPR is a three-pole fusible safety switch rated at 600A and 600V, designed for standard control panel and switchgear mounting. It fits common Series K configurations and uses Posi-Lok reverse pin for secure mechanical engagement. Ensure enclosure is compatible with indoor, dry environments (NEMA 1) and verify space within the panel to accommodate dimensions (11.13 in W x 21.69 in H x 9.89 in D).
Key specs include three-pole operation, fusible fuse configuration, 600A current rating, 600V voltage rating, NEMA 1 enclosure, Series K construction, and Posi-Lok reverse pin. It is UL Listed, supporting compliance with electrical safety standards. This combination delivers reliable isolation, effective overcurrent protection coordination, and robust performance in demanding industrial settings.
Yes. The NEMA 1 indoor enclosure is designed for dry indoor environments, and the three-pole, 600A fusible design handles high-current machine controls and motor feeders. Its compact footprint facilitates retrofits in existing panels, while Series K compatibility simplifies accessory integration and field upgrades, contributing to faster commissioning and reduced installation risk.
The product is UL Listed, which verifies adherence to recognized safety standards and supports regulatory compliance across North American facilities. While other certifications such as CE or IP ratings are not listed for this unit, UL Listing combined with the NEMA 1 enclosure provides confidence in safe operation, routine maintenance, and safe disconnection during servicing.
Posi-Lok reverse pin enhances mechanical reliability by securing handle position during vibration and maintenance cycles, reducing misoperation risks. The fusible design provides predictable current protection, potentially lowering arc flash exposure. With a one-year warranty (or 18 months from shipment) and Eaton’s support ecosystem, asset uptime is improved and total cost of ownership is reduced through longer service intervals and streamlined part availability.
