Federal Pacific NEF433020R Circuit Breaker, 20A, 3-Pole, 480V

Meet the Federal Pacific NEF433020R Circuit Breaker — a rugged, industrial-grade protection device engineered for 480V three-phase systems. This 20 A, 3-pole breaker is built for industrial electrical service, maintenance, and replacement projects. To ensure compatibility, verify fit by the part number NEF433020R and by your panel’s application requirements.

Key specifications

• Amperage: 20 A
• Poles: 3-Pole
• Voltage: 480V
• Part number: NEF433020R

Why this matters for your setup

• Coordinated protection for 480V, three-phase systems: The 3-pole design ensures simultaneous tripping across all phases, reducing the risk of unbalanced loads and equipment damage in industrial environments.
• Appropriate amperage for motor and equipment circuits: A 20 A rating supports common branch circuits in manufacturing, processing lines, and other heavy-duty applications without compromising protection.
• Durable, purpose-built for demanding environments: Designed to stand up to frequent switching, maintenance work, and the rigors of industrial service.
• Clear compatibility guidance: Use the part number NEF433020R to confirm fit with your panel and 480V application requirements. If you need help matching a part number or confirming compatibility, message us and we’ll assist.

Ideal use scenarios

• Replacing aging or failed breakers in 480V, three-phase distribution panels
• New installations in industrial facilities that operate 480V three-phase circuits
• Maintenance projects in manufacturing floors, processing plants, and data centers where Federal Pacific compatibility is specified

Practical guidance for selection and installation

• Always verify the panel’s specifications and the exact part number before purchase to ensure proper fit and safety.
• Confirm that your wiring and bus configuration match a 3-pole, 480V system to avoid nuisance trips or mismatch.
• When upgrading or replacing, consider the broader protection plan for your electrical distribution, including coordination with upstream breakers and the overall fault-clearing strategy.
