Eaton DH365SNRKLPR Heavy Duty Safety Switch - NEMA 3R
Part Number: DH365SNRKLPR
Quick Summary
Eaton DH365SNRKLPR Heavy Duty Safety Switch provides reliable isolation for three-phase systems in demanding industrial environments. This model is designed to simplify safe shutdowns while delivering robust protection at 400 A and 600 V. Operators often struggle with fuse handling, neutral switching, and mounting in tight spaces; this switch resolves those challenges with a fusible-with-switched-neutral configuration and a rugged enclosure. UL Listed certification confirms compliance with essential safety standards, while a NEMA 3R enclosure offers protection in outdoor, damp, or dusty installations. Series K compatibility ensures seamless integration with Eaton switchgear and control panels. For maintenance and retrofit projects, the 32.87 in depth and 74.34 in height provide a clear footprint, while Posi-Lok reverse pin eases handle operation.

FAQs
Begin with de-energizing the system and confirming absence of voltage. Mount the switch in a compliant enclosure, connect the three live lines to the input terminals, and wire the neutral through the fusible-switched path as specified. Verify torque requirements, test the Posi-Lok reverse pin operation, and perform a functional stop/start test before commissioning.
DH365SNRKLPR is designed for seamless Series K integration, ensuring consistent mechanical fit and electrical coordination with Eaton control panels and protective devices. Use correct rated conductors, verify enclosure clearances, and align mounting patterns to minimize wiring complexity and commissioning time.
Yes, the DH365SNRKLPR is UL Listed, confirming adherence to essential safety standards. It uses a NEMA 3R enclosure that offers outdoor-ready protection against rain, dust, and incidental exposure, enabling reliable operation in harsh industrial environments.
Yes. The DH365SNRKLPR features a Fusible with switched neutral configuration, simplifying wiring and improving fault isolation. Verify neutral switching requirements in your control scheme and ensure compatible fusing devices and protective relays are selected for your motor loads.
Regular inspections of connections, neutral path integrity, and Posi-Lok mechanism are recommended. The rugged NEMA 3R enclosure and UL Listed certification support longer service intervals and lower downtime. Over time, dependable isolation reduces unplanned outages, leading to lower maintenance costs and improved production throughput.
