Siemens HF364 - 200A, 600V, 3-Pole, Safety Switch

Designed for demanding industrial and commercial environments, the Siemens HF364 Safety Switch delivers safe, reliable electrical isolation with confidence. Rated for 200A and a maximum 600V, its 3-Pole configuration is ideal for three-phase systems, providing complete phase isolation when you need to service or reconfigure power circuits. With built-in support for proper lockout/tagout procedures and a proven ability to disconnect under load, the HF364 is built for both routine maintenance and high-stakes switching operations, offering long-term durability in tough work settings.

• 3-Pole design ensures full isolation across all phases in three-phase electrical systems.
• 200A current rating and 600V voltage rating accommodate mid-to-large feeders and equipment with confidence.
• Lockout/Tagout compatibility supports compliant, safe maintenance and servicing workflows.
• Dependable disconnection under load minimizes risk during switching, reducing downtime and safety concerns.
• Durable construction designed to withstand demanding industrial and commercial environments over the long term.

Ideal applications and scenarios

The HF364 is a strategic choice for facilities that require reliable isolation in critical electrical paths. Use it to isolate power to distribution panels, motor control centers, switchgear, and other three-phase circuits during maintenance, upgrades, or fault isolation. It helps ensure personnel safety by preventing inadvertent energization and supports safe, repeatable shutdown procedures in daily operations.

What makes it stand out

Unlike generic safety switches, the HF364 combines Siemens engineering excellence with a layout that emphasizes practical, on-site usability. The 3-Pole configuration aligns with standard three-phase systems, while the emphasis on lockout/tagout readiness and under-load disconnection addresses real-world maintenance workflows. This combination translates to faster, safer service windows and more predictable equipment behavior over time.
