Square D HU364 - 200A, 600V, 3-Pole, Safety Switch

Introducing the Square D HU364 Safety Switch—a rugged, high-performance disconnect designed for industrial and commercial environments where safe electrical isolation is non-negotiable. With its 200A current rating, 600V maximum, and a 3-pole configuration, it reliably isolates power across three phases, keeping personnel safe during maintenance and service operations.

• 200A, 600V three-pole design — handles demanding loads and three-phase systems with dependable isolation.
• NEMA 1 enclosure — compact indoor protection that stands up to daily industrial use.
• Lockout/Tagout compatibility — built to support standard safety protocols, ensuring circuits stay de-energized during servicing.
• Disconnection under load — engineered to interrupt power reliably when needed, reducing downtime and arc flash risk during emergency or routine switching.
• Durable, long-lasting construction — designed for enduring performance in busy electrical rooms and on manufacturing floors.

The HU364 is more than a switch; it’s a safety-first solution for power distribution. Use it as a service disconnect on indoor distributions, to isolate equipment like motors, transformers, and control panels, or as a primary shutdown in emergency scenarios. Ideal for facilities with strict safety policies and lockout/tagout programs, it provides clear, lock-ready access for authorized personnel while safeguarding other equipment from inadvertent energization.

Why choose Square D HU364 over generic switches? Its lineage matters. Square D, a trusted name in electrical safety, combines precise manufacturing, robust mechanicals, and a commitment to reliability. The HU364’s 3-pole design ensures all live conductors are safely isolated, meeting industry standards for indoor electrical safety and compliance.
