Square D H361RB - 30A, 600V, 3-Pole, Fused Disconnect Switch

Meet the Square D H361RB, a purpose-built fused disconnect switch engineered for demanding industrial and commercial environments where safe electrical isolation is non-negotiable. With a 30A rating and a 600V maximum, this 3-pole unit delivers dependable disconnection under load, empowering maintenance teams to work safely and efficiently.

Key benefits that matter in real-world operations:

• Three-pole isolation for complete shutdown. Every phase is controlled together, minimizing the risk of partial energization during service and reducing arc-flash exposure.
• Integrated fused protection. The built-in fuses provide immediate overcurrent protection, helping safeguard downstream equipment and wiring from faults before they cascade.
• Lockout/Tagout readiness. Designed to support safe lockout/tagout procedures, enabling technicians to lock the switch in the OFF position and clearly tag it for safe maintenance windows.
• Rugged, durable design. Built to withstand tough industrial environments and maintain reliable performance over time, even with frequent cycling and load changes.
• Versatile application. Ideal for motor feeders, drives, conveyors, HVAC equipment, and other 600V circuits that require a reliable, code-friendly service disconnect.

What problems does the Square D H361RB solve?

• Provides a definitive isolation point for maintenance, helping teams meet safety standards and prevent accidental re-energization.
• Delivers dependable shutdown under load, reducing fault propagation and downtime during commissioning and servicing.
• Offers durable performance in demanding facilities, lowering maintenance costs and extending the life of electrical infrastructure.

Who is this ideal for?

• Plant engineers and maintenance professionals responsible for safe, compliant electrical isolation in manufacturing or processing facilities.
• Electrical contractors upgrading or retrofitting 600V systems with reliable disconnects.
• Facility managers overseeing HVAC, pumping, and material-handling equipment that requires robust, user-friendly protection.

Why choose this configuration over alternatives?

• The 3-pole fused design provides comprehensive phase isolation with built-in protection, simplifying safety procedures and reducing the number of parts needed to achieve a complete disconnect.
• Designed specifically for environments where lockout/tagout and reliable disconnection under load are priorities, helping you stay compliant and minimize risk during maintenance windows.
