Siemens HF364 - 200A, Heavy Duty Fused Disconnect Switch

The Siemens HF364 - 200A Heavy Duty Fused Disconnect Switch is engineered for industrial and commercial environments that demand safe, reliable electrical isolation. Built for long-term durability, this switch delivers dependable disconnection under load while supporting proper lockout/tagout procedures to protect personnel during maintenance and servicing.

Designed to keep critical equipment safely offline when needed and to quickly re-energize once work is complete, the HF364 combines robust construction with proven electrical performance. Its fused design provides overcurrent protection, helping to minimize fault energy and reduce arcing risks in demanding electrical rooms and switchgear assemblies.

Key benefits and capabilities

• 200A amperage rating: Suitable for medium to large circuits, balancing control with protection for industrial loads.
• Heavy-duty fused disconnect: Provides reliable isolation and fault protection, even under load conditions.
• Lockout/Tagout compatibility: Facilitates safe maintenance practices by ensuring circuits remain de-energized during work.
• Reliable disconnection under load: Engineered to open circuits cleanly, minimizing surge and arcing during maintenance or emergency shutdowns.
• Durable construction: Built to withstand the rigors of busy electrical environments in factories, plants, and large facilities.
• Siemens reliability: Leverages Siemens engineering and quality standards to support ongoing system uptime and predictable performance.

Ideal applications

• Motor control centers and feeder applications where you need a clear, guaranteed disconnect point.
• Industrial and commercial power distribution panels requiring safe isolation for servicing and troubleshooting.
• Equipment rooms and service entrances where lockout/tagout procedures are routinely performed.
• HVAC, pumping, and heavy machinery installations that benefit from quick, dependable shutoff with protective fusing.

Why choose the HF364 over alternative disconnects

Unlike non-fused disconnects, the HF364 provides inherent overcurrent protection that helps safeguard equipment and operators. The combination of a robust heavy-duty enclosure, fused protection, and compatibility with lockout/tagout workflows makes it a practical, safer choice for facilities seeking reliable isolation and durable performance in challenging environments.

For teams prioritizing safety, reliability, and compliance, the Siemens HF364 200A Heavy Duty Fused Disconnect Switch offers a clear, purpose-built solution that aligns with real-world industrial needs. Invest in a switch that supports safer maintenance, reduces downtime risk, and helps protect both people and equipment.
