Meet the Square D D222NRB — a robust 60A, 2-Pole fusible switch engineered for dependable on/off isolation and precise overcurrent protection in demanding industrial and commercial environments. Built to endure vibration, dust, and temperature fluctuations, this switch keeps critical equipment protected and controls easily accessible when it matters most.

Key advantages at a glance

• 60 Amp, 2-Pole design provides reliable circuit interruption for dual-line protection, ideal for motor disconnects and branch circuits.
• Fusible switch configuration delivers integrated overcurrent protection in a compact form factor, simplifying panel design and maintenance.
• Compact footprint fits tight panel spaces and crowded electrical rooms without compromising performance.
• Durable, industrial-grade construction designed to stand up to demanding environments, reducing downtime and service calls.

Why this switch matters in your electrical system

When you need a dedicated motor disconnect or a reliable point of isolation for panelboards and branch circuits, the D222NRB delivers. Its2-Pole configuration ensures simultaneous interruption of both conductors, which is essential for safely servicing equipment and protecting personnel during maintenance. The fusible design adds an extra layer of protection by responding quickly to overcurrent conditions, helping prevent damage to downstream components and extending equipment life.

Ideal use scenarios

• Motor disconnects for pumps, fans, conveyors, and compressors in manufacturing or HVAC installations.
• Panelboard feeders where a compact, maintainable fusible switch is preferred for protection and isolation.
• Temporary or permanent control points in industrial setups that require quick, reliable shutoff.

What problems it solves

• Prevents uncontrolled electrical faults from propagating through circuits by providing a reliable isolation point.
• Reduces maintenance time with a straightforward on/off operation and clear, accessible switching.
• Supports safer lockout/tagout procedures by offering a dedicated disconnect for servicing equipment.

Practical guidance for use

• Pair with compatible fusing elements to align with your protective coordination strategy and local electrical codes.
• Install at readily reachable locations on motor circuits or branch feeders to streamline maintenance and troubleshooting.
• For panelboard deployments, verify mounting clearances and ensure proper wiring practices to maintain a clean, serviceable installation.
