Eaton DH326SNRKLP Heavy Duty Safety Switch - UL Listed
Part Number: DH326SNRKLP
Quick Summary
DH326SNRKLP Eaton heavy duty safety switch provides reliable power control for three-phase industrial equipment. Downtime and maintenance costs rise when heavy-duty switches are difficult to install, wire, or verify with a switched neutral. UL Listed safety certification and NEMA 3R enclosure support safe, compliant operation in harsh environments. Series K compatibility, Posi-Lok, and 600A at 240V help reduce risk, speed installation, and simplify maintenance. In practice, this translates to improved uptime, safer disconnections, and a clearer path to regulatory compliance. Engineers appreciate the comprehensive data sheet and downloadable resources for fast approvals. Procurement teams value the documented warranty and spare parts availability for lifecycle planning.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature: 600A amperage rating and 240V three-pole configuration enable robust protection for large three-phase loads. Business Impact: This capacity helps minimize voltage drop issues and reduces the risk of thermal damage during startup and load changes, improving equipment uptime. Application: Ideal for main feeders in heavy machinery, packaging lines, and processing equipment in rugged industrial environments. Feature: Fusible with switched neutral design enables selective feeder disconnection and safer maintenance sequences. Business Impact: Operators can isolate circuits cleanly, reducing arc flash exposure and enabling safer lockout/tagout procedures. Application: Suitable for motor control centers and process lines where controlled fuse operation is critical. Feature: NEMA 3R enclosure provides outdoor-ready, weather-resistant protection. Business Impact: Enhances reliability in outdoor plants or exposed industrial spaces, lowering environmental failure risk. Application: Exterior skid-mounted systems, outdoor switchgear enclosures, and exposed wiring areas. Feature: Posi-Lok ensures a secure handle engagement and resistance to vibration. Business Impact: Improves operator confidence, reduces nuisance trips, and extends interval between service calls. Application: Harsh manufacturing floors, packaging lines, and heavy-duty conveyors. Feature: Series K architecture provides proven compatibility with Eaton’s ecosystem and standard mounting practices. Business Impact: Streamlines procurement, minimizes integration risk, and accelerates site commissioning. Application: New builds and retrofit projects across industrial facilities seeking reliable, transferable components.

FAQs
Installation requires a sturdy mount that can support the unit’s 370 lb weight and its dimensions (32.87 in deep, 16.1 in wide, 74.34 in high). Use compatible Series K mounting hardware, connect three poles with a fusible switch and switched neutral, and place the enclosure in a NEMA 3R location suitable for outdoor or harsh environments.
DH326SNRKLP is a three-pole, 600A fusible safety switch rated for 240V. It uses a switched neutral and is designed for heavy-duty industrial circuits. The unit carries UL Listed certification and a Series K enclosure rated to NEMA 3R, supporting reliable performance in both indoor and outdoor installations. This combination supports compliance and predictable maintenance cycles.
Yes. The DH326SNRKLP uses a NEMA 3R enclosure designed for outdoor and harsh industrial environments, protecting internal components from dust, rain, and incidental contact. Its heavy-duty construction, 600A rating, and Posi-Lok feature promote safe disconnect operations, even in challenging installations where weather exposure and frequent door opening occur. The installation should still follow local codes and perform periodic inspections.
Posi-Lok provides a secure, positive handle engagement that resists unintended contact or vibration-induced micro-switches during maintenance or cycling. This improves operator safety, reduces nuisance trips, and simplifies early identification of a switch position. In high-vibration environments, Posi-Lok helps maintain correct alignment for safe disconnection, resulting in lower service calls and higher uptime.
