At 30A with a 3‑pole design, this device is built for maintenance, retrofit, and replacement projects where exact specifications matter, ensuring safe, consistent operation across your fleet of electrical equipment.

Core specifications

• Amperage: 30 A
• Poles: 3‑Pole
• Voltage: 480 V

Compatibility and installation considerations

Notes: Confirm fit and ratings before ordering. The NEF431030R part number is the best reference for compatibility with your equipment. This breaker is designed for three‑phase networks and should match panels and switchgear that accept a 3‑pole, 480V device. To maintain safe operation, verify that the panel frame, bus configuration, and interrupting rating align with your system’s requirements.

Why this breaker stands out

The NEF431030R is not just a spec match—it’s a targeted solution for lifecycle maintenance. By aligning precisely with 30A, 3‑pole, 480V needs, it minimizes downtime during upgrades and ensures consistent protection across all three phases, preventing partial energization and reducing the risk of motor and equipment damage.

Ideal use cases

• Maintenance cycles on industrial equipment powered by 480V three‑phase systems
• Retrofit projects where upgrading or replacing aging breakers is required
• Replacement for failed 3‑pole 480V breakers in manufacturing lines and heavy‑duty panels

Practical installation and operation tips

• Before ordering, verify the panel’s frame size and mounting style to ensure a seamless swap with the NEF431030R
• Check the panel’s rated interrupting capacity to match the protective needs of your 480V circuits
• Keep a spare NEF431030R on hand to minimize downtime during scheduled maintenance or unexpected outages
