Square D H222NRB 60A 2P 240V Safety Switch, NEMA 3R, Fusible | AmpState

Meet the Square D H222NRB 60A 2P 240V Safety Switch — a purpose-built equipment disconnect and isolation device designed for reliable operation at the point of use. With a 60 A, 2-pole configuration and a fusible design, this switch delivers robust protection for motors, pumps, conveyors, and other demanding loads while standing up to outdoor conditions thanks to its NEMA 3R enclosure.

• 60 A, 2-pole, 240 V — a solid, next-step solution for common industrial loads
• Fusible design provides built-in overcurrent protection and selective coordination with upstream devices
• NEMA 3R enclosure — weather-resistant for outdoor or damp locations, protecting the disconnect in harsh environments
• Original Square D part (H222NRB) — helps maintain BOM alignment for seamless replacement projects
• Ideal for replacement projects and stocking spares to minimize downtime and keep original part numbers intact
• Available from AmpState with support for compatibility checks and part-number matching

This safety switch is purpose-built for equipment that must be quickly and reliably isolated at the point of use. It’s particularly well-suited for outdoor installations or environments where exposure to weather is a consideration, yet you still need precise control over fault currents and safe shutdowns.

Who should consider the Square D H222NRB?

Maintenance teams, facilities engineers, OEM integrators, and electrical contractors who prioritize consistent part numbers, easy replacement, and outdoor-ready protection will find this switch a compelling choice. It supports efficient maintenance workflows by preserving BOM integrity and reducing the risk of mismatched components during replacements.

Use cases in the real world

Outdoor pump stations, conveyors in industrial yards, HVAC equipment with outdoor coils, and other point-of-use disconnect applications where a rugged, fusible safety switch can prevent costly downtime and protect sensitive equipment.

Why choose this option over alternatives?

Compared to generic disconnects, the H222NRB offers a fusible protection scheme built into a weather-rated enclosure, paired with a manufacturer-approved part that aligns with original drawings and overcurrent protection schemes. This means smoother replacements, fewer compatibility questions, and quicker returns to operation after maintenance or service events.
