Eaton DH327NRKLCR Heavy Duty Safety Switch - NEMA 3R
Part Number: DH327NRKLCR
Quick Summary
Eaton DH327NRKLCR heavy‑duty safety switch provides reliable power control for industrial electrical protection in harsh environments. Too often, operators face equipment downtime when switches cannot handle 800A at 240V or resist hostile conditions, leading to costly unscheduled stops. UL Listed certification supports safety compliance, the NEMA 3R enclosure protects against weather and moisture, and the rugged Series K design accepts fusible links with a solid neutral. For systems requiring fast, field-installable protection with dependable mis-wire protection and Cam-Lok reverse pin connections, this switch delivers measurable reliability and maintenance efficiency. This translates into improved uptime, safer maintenance windows, and simpler compliance reporting.
