NEF427090 | Circuit Breaker | 90A | 2-Pole | 480V

Meet NEF427090, an industrial circuit breaker designed for reliability in demanding electrical environments. Built to protect critical equipment and ensure safe operation, this 90 A, 2-pole device is ready for maintenance, retrofit, or replacement projects where exact specifications matter.

Key Specifications

• Amperage: 90 A
• Poles: 2-Pole
• Voltage rating: 480 V

Why this 2-Pole, 480V Breaker Stands Out

Unlike generic disconnects, the NEF427090 is purpose-built for industrial use, delivering precise protection for high-demand circuits. Its 90 A rating paired with a 480 V capability makes it ideal for protecting feeders and branch circuits in switchgear and control panels. The two-pole design ensures synchronized interruption across both conductors, helping maintain system safety and minimizing damage during fault events.

Use Cases

• Spare or replacement part for industrial equipment operating at 480 V
• Maintenance outages where you need an exact 90 A, 2-pole protection device
• Retrofits to bring legacy systems in line with current protection standards

Compatibility and Ordering Guidance

Before ordering, confirm fit and ratings against your equipment. The part number NEF427090 serves as the best reference for compatibility, ensuring you match the exact specifications required for your installation.

Practical Tips

• Keep a spare NEF427090 on hand to minimize downtime during planned maintenance
• Cross-check your panel labeling and service documentation to verify the 480 V rating aligns with your system voltage
