Square D H222NRB-SQUARE - 60A, 240V, 2-Pole, Fused Safety Switch

The Square D H222NRB-SQUARE 60A, 240V, 2-Pole Fused Safety Switch is engineered for safe, reliable electrical isolation in demanding industrial and commercial environments. Designed to support proper lockout/tagout procedures, it delivers dependable disconnection under load while standing up to day-to-day wear and harsh operating conditions.

Built for durability and safety, its NEMA 3R enclosure provides robust protection against weather and incidental impact, making it suitable for outdoor equipment rooms, service enclosures, and rugged shop floors. The fuse-based protection enhances fault-current interruption, reducing arc exposure and safeguarding downstream equipment during maintenance or fault events.

What makes this switch stand out

• Two-pole fused disconnect at 60A and 240V, ensuring a clear, complete isolation of both conductors.
• Fused protection delivers reliable current interruption under fault conditions, contributing to equipment longevity and safer servicing.
• Lockout/Tagout ready design supports standard safety procedures, helping teams confidently secure circuits during maintenance.
• Rugged NEMA 3R enclosure guards the switching mechanism from weather, dust, and incidental impact for outdoor or harsh indoor environments.
• Trusted Square D performance—a practical choice for facilities prioritizing consistent, industry-grade electrical safety components.

Ideal applications

Use the Square D H222NRB-SQUARE as the primary service disconnect for outdoor pumps, HVAC equipment, motor control centers, processing lines, and other machinery that requires a clearly defined, lockable isolation point. It’s well-suited for facilities that must adhere to lockout/tagout protocols and demand a reliable, under-load capable switching solution.

How it supports safety and compliance

By providing a dedicated, lockout-friendly isolation point, this fused safety switch helps maintenance teams work safely and efficiently. The 2-pole configuration isolates both legs of the circuit, minimizing re-energization risk during work, while the weather-rated enclosure ensures consistent protection in varied environmental conditions.
