Why the VH361RB stands out

• Three‑pole design is ideal for 3‑phase systems, providing coordinated isolation across all phases for motors, conveyors, pumps, and MCC feed circuits.
• Fused protection means the switch not only disconnects power but also provides overload protection, reducing the risk of damage to downstream equipment during faults.
• Designed to support proper lockout/tagout procedures, the VH361RB helps facilities meet safety compliance and streamline maintenance workflows.
• Durable construction delivers long‑term reliability in demanding environments, tolerating vibrations, temperature swings, and daily operating cycles without compromising performance.
• Clear, decisive disconnection under load improves safety during service, troubleshooting, and routine electrical maintenance.

Ideal use cases

• Disconnecting 3‑phase motors and ancillary equipment in manufacturing lines, processing plants, and packaging lines.
• Providing a safe isolation point for panel boards, electrical rooms, and service panels where maintenance lockout/tagout is required.
• Emergency or planned shutdowns where a reliable, fused disconnect improves fault containment and protection for downstream devices.

How this switch improves your operation

• Minimizes unplanned downtime by offering dependable isolation before maintenance or repair work.
• Enhances personnel safety through compatibility with established lockout/tagout protocols, ensuring a clearly isolated circuit during servicing.
• Protects downstream equipment from fault currents, helping extend the life of motors, drives, and other 3‑phase loads.
• Provides a straightforward, clear‑break disconnect point that reduces uncertainty during troubleshooting and testing.

Practical tips for use and care

To maximize performance and safety with the Square D VH361RB, pair the switch with correctly rated fuses for your 3‑phase load, verify proper wiring and terminal torque during installation, and maintain an up‑to‑date lockout/tagout log for every service event. Keep spare fuses accessible and inspect the switch regularly for signs of wear or corrosion, replacing components only with the same rating and specification to preserve protection integrity.

Choose the Square D VH361RB when you need a reliable, high‑performing fused disconnect switch that delivers safe isolation, compliant safety procedures, and durable service for 600V, 3‑pole electrical systems.
