Federal Pacific NB290 Circuit Breaker, 90A, 2-Pole, 240V

The Federal Pacific NB290 circuit breaker is a purpose-built, industrial-grade protective device designed for demanding electrical environments. As part of the Type NB family, this 90 A, 2-pole breaker is engineered to safeguard 240 V circuits, providing dependable overcurrent protection for power feeds, motors, heaters, and other high-load equipment in industrial service, maintenance, and replacement projects.

Why choose the NB290 for your installation

• Accurate ampere protection: 90 A rating ensures your circuits stay protected from overloads while allowing normal operation of connected equipment.
• Two-pole design: Protects both hot legs of a 240 V circuit, ensuring comprehensive fault interruption and safer, more reliable operation.
• Type NB compatibility: Specifically crafted for NB-series panels and assemblies, helping streamline replacements and field service in facilities that rely on Federal Pacific components.
• Part-number-driven fit: Use the NB290 part number to verify compatibility with your panelboard and application requirements—critical for correct sizing and safe operation.

Concrete use cases

• Upgrading or replacing aging protection on industrial feeders feeding 240 V machines and equipment.
• Maintenance projects where a known, compatible NB-series breaker is required to minimize panel rework.
• New installations in facilities that maintain Type NB panel layouts and rely on NB-series protection devices.

What this means in real-world terms

With the NB290 installed, you gain a reliable, straightforward path to interrupt fault currents on a 240 V, two-hot-leg system. The part-number focus helps technicians quickly confirm that the device matches your panel’s listing and the application’s electrical demands, reducing guesswork during replacements and routine servicing.

Practical guidance for a smooth fit

• Always verify fit by the exact part number (NB290) and cross-check it against your panel’s listing and the load profile of the circuit you intend to protect.
• Consider the installation context: industrial environments may present vibration, temperature, and accessibility challenges—plan mounting and wiring accordingly.
• If you’re unsure about compatibility, reach out for expert assistance to confirm that NB290 aligns with your NB-series gear and your specific electrical requirements.
