Siemens HF364R 200A 3P 600V Safety Switch, NEMA 3R, Fusible | AmpState

Siemens HF364R 200A 3P 600V Safety Switch is a robust, point-of-use disconnect designed to deliver reliable isolation for demanding industrial environments. With a NEMA 3R enclosure and a fusible design, this switch is built to withstand outdoor application conditions while providing precise protection for your electrical feeders and equipment.

Key features that matter in real-world setups:

• 200 A, 3-Pole, 600 V configuration delivers solid fault isolation for demanding loads, including motors, transformers, and feeders.
• NEMA 3R enclosures mean weather-resistant performance for outdoor installations, rain, snow, and incidental moisture won’t compromise safety or reliability.
• Fusible design supports selective coordination and fast interruption, helping minimize damage to downstream equipment and reducing downtime during faults.
• OEM BOM alignment—designed to match the original Siemens part number HF364R, making replacements and stocking spares straightforward and error-free.
• Smooth installation and serviceability for routine maintenance, fuse replacement, and quick reassembly in field or panel environments.

This safety switch is ideal for replacement projects where staying on the exact original part number is critical for compatibility and downtime planning. It’s also a smart choice for stocking spares to keep your BOM consistent and your uptime uninterrupted.

Who benefits most from the HF364R:

• Facilities upgrading outdoor equipment or aging switchgear that requires a proven, manufactuer-specific part
• Maintenance engineers needing a reliable, code-compliant disconnect for outdoor feeders and control circuits
• Procurement teams seeking a straightforward cross-reference to maintain BOM integrity and reduce part-number mismatches

How it compares to other options:

• Compared with non-fusible or non-weather-rated switches, the HF364R offers integrated protection with outdoor readiness, improving safety and reliability in harsh environments.
• Its OEM-aligned part number helps prevent mis-orders and accelerates stocking, unlike generic equivalents that require additional cross-referencing.

Practical tips for use:

• Verify fuse types and ratings required by your load profile and local electrical codes before installation.
• Plan for lockout/tagout procedures during fuse replacement and maintenance to ensure safe service.
• Keep a small inventory of compatible fuses on hand to minimize downtime when replacements are needed.
• If you’re unsure about compatibility with your panel or downstream devices, message us—AmpState can help confirm fit and cross-reference requirements.
