Square D HU364 - 200A, 600V, Heavy Duty Fused Safety Switch

Square D HU364 is a 200A, 600V Heavy Duty Fused Safety Switch engineered for reliable electrical isolation in demanding industrial and commercial environments. Built to endure daily operation, it delivers a dependable disconnection under load and supports proper lockout/tagout procedures to keep personnel safe during maintenance and servicing.

Key Specifications

• Amperage Rating: 200A
• Voltage Rating: 600V
• Product Type: Heavy Duty Fused Safety Switch
• Brand: Square D
• Model: HU364

Why the HU364 Stands Out

• Fused protection that interrupts fault currents efficiently, safeguarding downstream equipment and enabling smoother operation of your electrical system.
• Designed to support lockout/tagout procedures, enhancing on-site safety during maintenance and preventing accidental re-energization.
• Built for long-term durability in industrial settings, delivering consistent performance and reliable isolation year after year.
• Clear, positive electrical isolation when the switch is opened, helping technicians verify de-energized circuits before work begins.

Typical Applications & Use Scenarios

The HU364 is well-suited for industrial and commercial power distribution where a robust, fused disconnect is needed. Use it as the primary service disconnect for large equipment, as a protective control point in distribution panels, or as a dedicated isolation switch for maintenance shutdowns in manufacturing facilities and warehouses.

Installation, Safety & Maintenance Guidance

Rely on the HU364 for dependable disconnection under load and integrate it into your safety program with established lockout/tagout practices. Regularly inspect the switch for signs of wear, ensure the enclosure remains intact, and verify that the device continues to meet your circuit’s 200A/600V requirements. When in use, keep the operating area clear and follow standard electrical safety protocols to maximize uptime and personnel safety.

Choose the Square D HU364 when you need a purpose-built, industrial-grade fused safety switch that prioritizes safety, reliability, and longevity—providing essential isolation for demanding electrical systems.
