• Amperage: 100A
• Voltage: 240V
• Poles: 3-Pole
• Fusible: Yes (integrated fusible safety switch)
• NEMA Rating: 3R, suitable for outdoor or weather-exposed installations
• Application: Ideal for motor disconnects, panelboards, and branch circuit protection when a compact, maintainable fusible switch is required

Why this fusible safety switch stands out

The DG323NRB delivers a compact, service-friendly solution that combines reliable isolation with built-in overcurrent protection. Unlike non-fusible disconnects, this unit uses replaceable fuses to tailor protection to your specific load, helping safeguard motors, feeders, and control circuits from overloads while keeping maintenance straightforward and cost-effective.

Ideal applications

• Motor disconnects in small to mid-size industrial equipment and manufacturing lines
• Panelboard feeders where a dedicated, locally accessible safety switch is needed
• Branch circuit protection for outdoor or exposed installations that require a robust, weather-resilient enclosure

What problems it solves

When you need immediate, reliable isolation combined with adjustable protection for three-phase systems, the DG323NRB provides a clear, maintainable path. It simplifies routine servicing by using standard fuses you can source quickly, reduces downtime during protection device replacements, and ensures a safe, single-point disconnect for complex electrical feeds.

Practical considerations and setup insights

• Design aligns with three-phase 240V systems, making it suitable for 3-pole motor circuits and related equipment
• The NEMA 3R enclosure enables outdoor or partially sheltered installations without compromising protective performance
• Plan fuse selection based on your motor load and startup characteristics to ensure appropriate protection without nuisance blows
• Maintain a simple spare-fuse inventory on-site to minimize downtime during fuse replacements
• Install with proper clearances and secure mounting to preserve safe operation and easy access for maintenance

Choose the Eaton DG323NRB for a compact, reliable, and maintainable fusible safety switch that delivers solid isolation, targeted overcurrent protection, and the durability needed for demanding environments. Its combination of 100A, 240V, 3-pole configuration and NEMA 3R enclosure makes it a practical, long-lasting choice for motor control, panelboard protection, and robust branch circuit safeguarding.
