Square D H364 - 200A, 3-Pole, Fused Safety Switch

The Square D H364 is a rugged, high-performance 200A, 3-pole fused safety switch engineered for demanding industrial and commercial environments. It provides safe, reliable electrical isolation and works in tandem with lockout/tagout (LOTO) procedures to protect personnel during maintenance and service work. With dependable disconnection under load, it helps prevent accidental energization and supports safe, compliant shutdowns in busy facilities.

• 200A amperage rating paired with a 3-pole configuration ensures complete isolation of all live conductors, delivering a clean, safe disconnect for heavy equipment and motor loads.
• Fused protection integrates overcurrent and short-circuit protection directly into the switch, reducing components and simplifying wiring pathways while preserving fast response during fault conditions.
• Safe isolation under load capability minimizes risk when servicing equipment, allowing maintenance teams to work with confidence in energized environments that require controlled shutdowns.
• Lockout/Tagout readiness designed to support standard LOTO procedures, with compatibility for padlocks and tags to ensure clear, enforceable safety during maintenance.
• Durable, long-term reliability built for industrial use, delivering consistent performance in demanding settings and reducing downtime due to unexpected switch failures.
• Versatile applications ideal for motor control centers, service entrances, manufacturing lines, and other electrical assemblies that require both disconnect and overcurrent protection in a single unit.

Designed for operators who demand safety without sacrificing efficiency, the Square D H364 provides precise control, straightforward maintenance, and dependable protection. If you’re upgrading an electrical distribution panel or configuring a new system that prioritizes safe isolation, reliable disconnection, and compliant maintenance procedures, the H364 is a purpose-built choice that aligns with your safety and performance goals.
