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

Square D VHU361N is a rugged 3-pole fused disconnect switch designed to deliver dependable electrical isolation in demanding industrial and commercial environments. With a 30A rating and a 600V maximum, it provides a safe, controlled disconnect for equipment and circuits, ensuring maintenance teams can lock out and tag out with confidence while protecting personnel and integrity of the system.

Key features that matter in daily operation

• Three-pole isolation ensures all live conductors are simultaneously opened, reducing the risk of partial energization during maintenance.
• Fused protection adds overcurrent protection directly in the switch assembly, helping to limit fault energy and minimize damage to downstream equipment.
• 600V capability supports a wide range of industrial and commercial power distribution setups commonly found in manufacturing floors, facilities, and HVAC systems.
• Electrical safety and compliance designed to support proper lockout/tagout procedures, promoting safer work practices and adherence to safety standards.
• Durable, purpose-built design built to withstand the rigors of daily operation in demanding environments, reducing maintenance intervals and downtime.

Ideal applications

This fused disconnect switch is well-suited for feeding motor circuits, control panels, and power distribution feeds where quick, reliable isolation is essential. Typical use cases include motor starters for conveyors, pumps, compressors, and HVAC equipment, as well as feeders in control rooms and switchgear assemblies where strict lockout/tagout controls are required.

Why choose the Square D VHU361N

• Clear, confident isolation with a dedicated fuse path that protects both the switch and downstream circuitry during faults.
• Safety-first design aligns with lockout/tagout processes, helping personnel perform maintenance without risk of unexpected energization.
• Reliable performance optimized for enduring operation in environments that demand minimal downtime and consistent fault protection.

Practical considerations and best practices

When selecting the VHU361N, confirm that your installation voltage and load current align with the 600V / 30A ratings and that you’re coordinating with compatible fuses for your system. Installers should follow your facility’s LOTO procedures, verify all connections are secure, and ensure the switch is integrated into an appropriately rated disconnect enclosure for protection against dust, moisture, and impact in harsher environments.
