Square D H322NRB-SQUARE - 60A, 240V, 3-Pole, Fused Safety Switch

The Square D H322NRB-SQUARE is a 60A, 240V, 3-pole fused safety switch designed to deliver clean, reliable electrical isolation in demanding industrial and commercial environments. Built to support proper lockout/tagout procedures, it provides dependable disconnection under load, enhancing personnel safety and protecting downstream equipment during routine maintenance or fault events.

Key advantages

• Three-pole isolation fully interrupts all three phases, ensuring complete electrical disconnection for safer service work on three-phase systems.
• Fused protection offers controlled interruption of fault currents, helping minimize arc flashes and downstream damage when abnormalities occur.
• 60A, 240V rating aligns with common industrial equipment and motor circuits, delivering robust protection without unnecessary downtime.
• NEMA 3R enclosure provides reliable performance in indoor and outdoor or damp environments, making it suitable for equipment rooms, loading docks, and exposed outdoor installations.
• Lockout/Tagout readiness supports compliant maintenance practices, enhancing safety protocols during servicing and inspections.
• Durable, industrial-grade design from a trusted Square D/SCHNEIDER ELECTRIC lineage, built to withstand daily operation in busy facilities.

Who benefits

• Maintenance teams needing a reliable, code-compliant shutdown for three-phase equipment
• Facilities with motor control centers, conveyors, pumps, or HVAC systems requiring safe isolation
• Outdoor or damp-location installations where robust enclosure protection is essential
• Safety managers prioritizing clear lockout/tagout workflows and predictable fault current handling

Use cases and scenarios

In a manufacturing line, the H322NRB-SQUARE serves as the primary disconnect for a 60A motor circuit, allowing technicians to lock out power before performing routine maintenance. On an outdoor equipment pad, its NEMA 3R enclosure protects the disconnect from weather while preserving safe isolation. In a warehouse, it acts as a centralized safety switch for multiple 3-phase loads, ensuring a definitive de-energized state during servicing.
