Meet Siemens HNF367R, a robust safety switch engineered for dependable equipment disconnect and isolation at the point of use. Whether it’s for a manufacturing line, outdoor enclosure, or critical process equipment, this 3-pole, 800 A switch delivers clear separation when you need it most. Available in both fusible and non-fusible configurations, the HNF367R is designed to fit a range of protection schemes while keeping installation clean and simple.

NEMA 3R-rated enclosure provides weather-resistant performance, making it suitable for outdoor installations or harsh environments. With a 600 V rating, it supports industrial feeders and motor circuits common in factories, facilities, and heavy equipment rooms.

Key differentiators that matter

• Exact part number availability: Siemens HNF367R is the precise component you need for direct replacement or stocking spare parts, reducing misorders and downtime.
• 800 A, 3-pole configuration: Handles high-current disconnects for large motors and equipment with a single, reliable switch.
• NEMA 3R outdoor/indoor versatility: Durable enclosure designed for weather exposure without compromising safety.
• Fusible and Non-Fusible options: Choose integrated fusing for protection or a non-fusible disconnect when your system already has upstream protection or specific coordination needs.
• Support from AmpState: We help confirm fit and compatibility; just message us to verify that HNF367R matches your panel and application.

Practical use cases

• Maintenance shutdowns for large motors, conveyors, pumps, and HVAC equipment where a clean isolation point is required at the device location.
• Panel builders specifying a standard, reliable disconnect across industrial controls and switchgear assemblies.
• Spare inventory for facilities with frequent equipment changes or upgrades, ensuring quick replacement with the exact Siemens part.
• Outdoor installations such as service entrances, outdoor motor control centers, or protected equipment bays where rain, ice, or debris resilience matters.

Why this matters for you

The HNF367R combines Siemens engineering reliability with flexible configuration to support diverse protection schemes. The 800 A current rating ensures you can safely disconnect high-load equipment, while the 600 V rating covers a wide range of industrial feeders. The NEMA 3R rating translates into confidence outdoors or in damp interiors, reducing the risk of corrosion or shorts caused by the elements.
