Meet the Cutler-Hammer DG222NRB — a compact, durable solution that blends reliable on/off isolation with built-in overcurrent protection. Rated at 60A and 240V, this fusible switch is purpose-built for industrial and commercial environments where space, accessibility, and safety matter.

The DG222NRB is a true two-in-one device: a manual switch plus replaceable fuses, all housed in a rugged NEMA 3R enclosure. This combination delivers straightforward isolation for maintenance and dependable protection for downstream equipment, reducing the need for multiple separate components in your electrical layout.

Why this fusible switch stands out

• 60A at 240V capability— designed to handle common motor loads, panelboards, and branch circuits without sacrificing protection or control.
• Fusible protection— integrated fusing provides overcurrent protection directly in the switch, streamlining wiring and coordination with downstream devices.
• NEMA 3R enclosure— built for reliability in outdoor or exposed environments, with weather-resistant construction that keeps performance consistent in challenging conditions.
• Compact, maintainable design— a streamlined footprint that fits into existing layouts and simplifies field service, with easy fuse access for quick maintenance.

Practical uses and scenarios

• Motor disconnects for outdoor equipment, such as pumps, fans, or conveyors, where rapid isolation is essential for maintenance and safety.
• Main or branch protection in panelboards where a single, dependable device handles both switching and overcurrent protection.
• Protection for HVAC systems and other industrial machinery installed in exposed or outdoor locations, reducing the need for additional protective hardware.

What this means for you

Choosing the DG222NRB means you’re investing in a proven, purpose-driven disconnect switch from a trusted name. You gain a space-efficient solution that doesn’t compromise on safety or reliability — ideal for applications where a compact, maintainable fusible switch is a requirement, not an afterthought.

Install considerations: ensure compatibility with 60A, 240V fuse elements and comply with local electrical codes for NEMA 3R enclosures. Plan for accessible mounting and routine checks to keep the protection and isolation functions ready when you need them.
