Siemens HNF361R - 30A, 600V, Fused Disconnect Switch

Introducing the Siemens HNF361R, a purpose-built fused disconnect switch engineered to deliver safe, reliable electrical isolation in demanding industrial and commercial environments. With a 30A rating and a 600V maximum, this switch provides dependable disconnection under load and supports robust lockout/tagout procedures, helping keep maintenance teams safe while minimizing downtime.

Why the Siemens HNF361R stands apart

• Integrated fusing for precise protection. The fused design interrupts fault currents quickly, shielding motors, wiring, and downstream equipment from damage during faults or overloads.
• Rugged, weather-ready enclosure. The NEMA 3R enclosure is built to withstand outdoor and exposed installations, delivering durable performance in varying conditions.
• Lockout/Tagout readiness. Engineered to support safe maintenance practices, enabling secure de-energization during servicing without vendor-specific adapters or workaround steps.
• Long-term reliability in tough environments. Designed for continuous operation in industrial settings, reducing maintenance cycles and extending system life.

Ideal applications

Perfect for circuits that require reliable isolation of powered equipment, such as motor drives, pumps, conveyors, HVAC equipment, and other line-side loads in both manufacturing facilities and commercial complexes. It’s a practical choice wherever routine servicing or emergency shutdowns demand a dependable, clearly defined disconnect.
