Square D VH363 - 100A, 600V, 3-Pole, Safety Switch

The Square D VH363 Safety Switch delivers trusted electrical isolation for demanding industrial and commercial environments. With a 3-pole design that cleanly disconnects all three live conductors, it ensures safe maintenance and reliable operation when the system is energized, supporting proper lockout/tagout procedures and providing dependable disconnection under load.

Key capabilities

• Three-pole isolation stops all phases simultaneously, delivering complete de-energization for safer servicing and downtime management.
• 100A current rating supports a wide range of medium-duty industrial loads while maintaining robust performance.
• 600V maximum voltage compatibility with common three-phase power distribution systems found in factories, plants, and large commercial facilities.
• Lockout/tagout readiness designed to integrate smoothly with safety protocols, helping facilities meet workplace safety requirements and enhance technician protection.
• Durable, long-term reliability built to withstand the rigors of busy environments, reducing unplanned downtime and maintenance hassles.
• Easy panel integration compact form factor and straightforward operation streamline installation in existing electrical assemblies.

Ideal applications

Best suited for machines and circuits that demand a dedicated main disconnect, including manufacturing lines, processing equipment, HVAC systems, conveyors, pumps, and other three-phase loads where safe maintenance and immediate isolation are priorities.

Why this safety switch matters

In environments where energy isolation is non-negotiable, the VH363 provides a reliable, clearly identifiable break in the circuit. It minimizes arc-flash risk during servicing, supports orderly lockout/tagout practice, and contributes to smoother maintenance workflows by offering a predictable, tested mechanism for disconnecting power.
