Square D VHU361N - 30A, 600V, 3-Pole, Fused Disconnect Switch

Square D VHU361N is a 30 A, 600 V, 3‑pole fused disconnect switch engineered for safe electrical isolation in demanding industrial and commercial environments.

Designed to support proper lockout/tagout procedures, it delivers reliable, fault‑clearing disconnection under load and is built for long‑term durability in challenging installations.

What makes it stand out

• Integrated overcurrent protection: the fuse element within the switch provides immediate fault interruption, protecting downstream equipment and wiring.
• Three‑phase isolation: the 3‑pole design disconnects all live conductors at once for a clean, safe shutdown of three‑phase machinery.
• Lockout/Tagout compatibility: grab‑handle and access points are purposefully sized for secure padlocks and tagged authorization, helping you meet safety protocols.
• Rugged, durable construction: built to withstand demanding environments, with components designed for repetitive operation and long service life.
• Versatile installation: suitable for mounting where a standalone switch is required or integrated into panel or switchgear setups.

Practical applications

• Motor‑driven equipment such as conveyors, pumps, fans, and compressors in manufacturing facilities, warehouses, and processing plants.
• Maintenance and calibration tasks where a verified, isolated power source is essential for worker safety.
• Electrical service disconnects in commercial settings controlling large HVAC units or critical process lines.

Who should consider the Square D VHU361N?

• Electrical contractors wiring new panels or upgrading safety controls in medium‑ to large facilities.
• Facilities maintenance teams seeking reliable, code‑compliant isolation for mechanical equipment.
• OEMs integrating a ready‑to‑install fused disconnect switch into machinery and turnkey power distributions.

Maintenance and best practices

• Regularly inspect fuse elements and contact surfaces for signs of wear or arcing; replace fuses as part of your maintenance schedule.
• Keep the disconnect accessible and clearly labeled; document lockout/tagout points for quick, safe shutdowns.
• Pair with appropriate wiring and enclosure hardware, ensuring clean, secure connections and protection against environmental factors.
