Engineered for dependable equipment shutdowns, the Siemens HF364NR 200A 3P 600V Safety Switch is a rugged, ready-to-deploy solution for disconnecting and isolating electrical equipment at the point of use. With a NEMA 3R enclosure, this switch is built to withstand outdoor and harsh environments, making it a smart choice for installation racks, service entrances, and rugged industrial spaces where reliability matters most.

What sets the HF364NR apart

• 200 A, 3-pole, 600 V — robust current handling for 3-phase systems and demanding industrial applications.
• NEMA 3R enclosure — weather-resistant protection suitable for outdoor and damp locations, reducing the need for extra housing.
• Fusible configuration — designed to accommodate fuse protection for coordinated overcurrent protection, delivering a streamlined path from disconnect to protection.
• Direct part-number match — a precise fit for panel builders and maintenance teams who value quick, accurate procurement with less guesswork.
• Point-of-use disconnect and isolation — built to safely isolate equipment during maintenance or servicing without routing power through upstream panels.
• Part availability — HF364NR is available from AmpState, with support to verify compatibility and fit for your specific installation.
