Siemens HF364 - 200A, 600V, Fused Disconnect Switch

The Siemens HF364 is a high‑performance 200A, 600V fused disconnect switch engineered for reliable electrical isolation in demanding industrial and commercial environments. Built to support proper lockout/tagout procedures and safe maintenance, it delivers dependable disconnection under load, helping technicians work confidently around energized systems.

Key advantages that set the HF364 apart

• Integrated protection and isolation: This fused disconnect switch combines overcurrent protection with a clear disconnection path, simplifying electrical protection schemes and reducing the number of components you manage on site.
• Lockout/Tagout (LOTO) readiness: Designed to complement LOTO practices, it provides a reliable, provincially compliant point of isolation for servicing and maintenance tasks.
• Safe under-load disconnection: The HF364 is engineered to reliably interrupt and isolate circuits even when loads are energized, reducing risk during switching operations.
• Rugged indoor enclosure (NEMA 1): Built for indoor use in controlled environments, offering solid protection against dust and incidental impacts typical of facility spaces.
• Specified for high‑demand applications: With a 200A rating and a 600V maximum, it accommodates substantial feeders and motor circuits common in manufacturing, processing, and facility infrastructure.

Where you’ll typically use it

• Industrial facilities with heavy machinery, conveyors, and compressors that require safe isolation for routine maintenance.
• Commercial complexes and campuses where power feeders must be safely disconnected for service or emergency shutdowns.
• Motor control centers, distribution panels, and large control panels needing a dedicated fused disconnect as part of the protection scheme.
• HVAC and water pumping systems where reliability and predictable isolation minimize downtime during servicing.

Why this matters for safety, reliability, and compliance

The HF364 is more than a switch; it’s a critical safety link in your electrical safety program. By providing a clearly defined isolation point that supports LOTO procedures, it helps prevent accidental energization during maintenance. Its fused design offers additional short‑circuit protection, helping minimize fault propagation and protect downstream equipment. In environments where uptime matters, the HF364 delivers predictable performance and long‑term durability that you can rely on year after year.
