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

The Siemens HF364 fused disconnect switch is built for rugged industrial and commercial electrical rooms where safe, reliable isolation matters. With a 200A rating and 600V maximum, this switch delivers a clear, controlled disconnect and supports lockout/tagout procedures, helping maintain operator safety and system reliability during servicing or maintenance.

Key Features and Benefits

• Definitive load interruption: The fused disconnect design provides reliable disconnection under load, protecting circuits and downstream equipment during maintenance.
• High-current capability: Amperage rating of 200A and voltage rating of 600V make the HF364 suitable for a wide range of industrial and commercial applications.
• Lockout/Tagout compatibility: Built to integrate seamlessly with standard safety procedures, enhancing compliance and worker safety during service interventions.
• Durable construction: Designed for long-term durability in demanding environments, reducing maintenance needs and downtime.
• Clear isolation for reliability: Provides dependable electrical isolation that supports consistent operation of connected equipment over time.

Specifications

• Amperage Rating: 200A
• Voltage Rating: 600V
• Product Type: Fused Disconnect Switch
• Brand: Siemens
• Model: HF364

Ideal Applications

• Industrial facilities and manufacturing lines requiring safe, reliable electrical isolation during maintenance
• Commercial building service disconnects where clear, controllable shutdowns are essential
• Control panels and distribution systems that benefit from integrated fused protection
• Maintenance shutdowns and lockout/tagout procedures to protect personnel and equipment

Why the HF364 Stands Out

• Siemens engineering delivers trusted performance and consistent disconnection under load, reducing downtime and maintenance risk.
• The fused element provides an additional layer of circuit protection within a compact disconnect switch, supporting safer fault isolation.
• Designed for longevity in busy electrical rooms, the HF364 combines reliability with straightforward integration into existing panels and systems.

Usage Tips and Best Practices

• Plan lockout/tagout procedures in advance and ensure all affected personnel are informed before initiating maintenance.
• During installation or replacement, inspect fuses and connections for secure seating and proper torque as part of routine startup checks.
• Coordinate maintenance windows to minimize impact on production schedules while keeping safety as the top priority.
