The H364 is purpose-built for facilities where uptime and personnel safety are non-negotiable. Its robust construction provides dependable disconnection even when equipment is operating under load, helping to minimize arcing risks and facilitating a safer maintenance workflow. By integrating smoothly with lockout/tagout practices, it offers a clear, verifiable energy isolation point—reducing the chance of accidental re-energization during servicing.

Ideal use cases include main service disconnects, feeder isolation for large machinery, and service points within warehouses, manufacturing floors, processing plants, or any commercial space that relies on disciplined electrical safety protocols. Whether you’re upgrading an aging disconnect or specifying a durable, code-conscious solution for new builds, the H364 delivers consistent performance where it matters most.

Why this matters in real-world scenarios: a higher-capacity, 600-volt disconnect like the H364 can simplify system design by providing a single, reliable isolation point for multiple downstream circuits. It supports routine maintenance without compromising safety, and it helps facilities meet regulatory requirements for lockout/tagout compliance and safe energy control.

Key considerations and practical tips

• Match the 200 A rating to your feeder and motor loads to ensure a clean, effective isolation point.
• Integrate with standard lockout devices and safety tags to streamline maintenance workflows.
• Plan for periodic functional checks to verify the disconnect closes and opens smoothly under load conditions.
• Use as part of a broader electrical safety program to reinforce clear, enforceable isolation procedures across the facility.
