Eaton DG223NRB - General-Duty, Fusible, Safety Switch, NEMA 3R

When dependable isolation and reliable overcurrent protection are non-negotiable, the Eaton DG223NRB General-Duty Fusible Safety Switch delivers. This compact, maintainable safety switch pairs a straightforward on/off disconnect with fuse protection, engineered to withstand the rigors of demanding industrial and commercial environments. With a NEMA 3R enclosure, it’s built to perform where weather and exposure are factors, without sacrificing ease of service or footprint.

Key advantages that matter on the job

• Integrated fuse protection combines disconnect and overcurrent protection in a single, compact unit, reducing wiring complexity and simplifying protection coordination for downstream equipment.
• NEMA 3R enclosure provides weather-resistant protection for outdoor installations and semi-exposed spaces, helping equipment stay safe in varied conditions.
• General-duty design accommodates a broad range of motor loads and branch circuit protections, making it a versatile choice for diverse applications.
• Maintenance-friendly with a straightforward fuse replacement approach, enabling quicker service and reduced downtime when fuses need changing.
• Compact footprint fits neatly into panelboards and electrical rooms where space is at a premium, without compromising protection or performance.

Ideal applications

The DG223NRB is purpose-built for motor disconnects, panelboards, and branch circuit protection in environments where a robust, easy-to-service fusible switch is required. It’s well-suited for HVAC assemblies, pumps and conveyors, outdoor equipment enclosures, and general industrial/commercial electrical distribution where reliable isolation and immediate fault interruption are essential.

How it works

In normal operation, the DG223NRB provides a clear, visible disconnect for maintenance and safety. When fault current occurs, the integrated fuse(s) interrupt the circuit, isolating the connected equipment and helping prevent damage to motors, drives, and downstream circuits. The result is faster fault clearing, safer maintenance procedures, and simplified wiring compared with standalone disconnect and fuse assemblies.

What sets the DG223NRB apart

• One integrated solution delivers both isolation and overcurrent protection, reducing the need for separate components and streamlining installation.
• Rugged, weather-ready design with a NEMA 3R enclosure supports reliable outdoor or semi-exposed use without additional housing or protection.
• Efficient maintenance—replace fuses quickly on-site to minimize downtime and keep critical equipment online faster.
• Versatile general-duty rating makes it suitable for a wide variety of loads and configurations, helping simplify electrical procurement and stock management.
