Federal Pacific NC240 - 40A, 2-Pole, Miniature Circuit Breaker (MCB)

The Federal Pacific NC240 is a purpose-built 40A, 2-Pole Miniature Circuit Breaker (MCB) designed to protect your electrical systems where reliability matters most. This compact, two-pole device is ready for installation in panelboards, switchboards, and control panels, delivering dependable overcurrent protection in demanding industrial, commercial, and OEM environments.

• Current rating: 40A with a 2-Pole configuration, providing robust protection for two conductors in a single, space-efficient unit.
• Two-pole design ensures simultaneous disconnection of both supply lines, reducing arc risk and improving overall fault safety.
• Versatile integration compatible with standard panelboards, switchboards, and control panels, making it suitable for new deployments or retrofits in existing electrical architectures.
• Overcurrent protection you can rely on engineered to interrupt faults and overloads, helping shield wiring, components, and connected equipment from damage in distribution panels and motor control centers.
• Ideal for multiple applications especially where dependable protection is critical—industrial facilities, commercial installations, and OEM equipment builds.

Why this NC240 matters in your electrical system:

• Targeted protection for critical circuits: Use it on branch circuits feeding motors, heaters, and other high-demand loads to prevent overheating and insulation damage.
• Simplified maintenance and replacement: Designed for straightforward installation and easy swap-in within existing Federal Pacific installations, preserving panel geometry and wiring layouts.
• Practical flexibility: Suitable for distribution panels and motor control centers where compact, reliable overcurrent protection is essential to keep downtime to a minimum.
• Compared to single-pole options: The two-pole configuration provides enhanced safety by disconnecting both conductors together, delivering better protection during faults.

Practical use cases

• Motor control centers and feeder circuits where reliable interruption of both hot lines is crucial for safety and equipment protection.
• Industrial and commercial panelboards that require compact, dependable protection without sacrificing performance or ease of installation.
• OEM control panels where a robust, standard-protection component can simplify wiring, service, and future upgrades.

Pro tips for best results:

• During installation, ensure connections are clean, tight, and torqued to panel specifications to prevent nuisance trips or overheating.
• Keep the enclosure dry and free of dust to maintain reliable contact integrity and long-term performance.
• Use as part of a comprehensive protection strategy that includes proper wiring sizing and regular inspection of protective devices.

The NC240 delivers a focused, reliable solution for safeguarding circuits in distribution panels and motor control centers. Its 40A rating, sturdy 2-pole design, and panel-friendly form factor make it a solid choice for professionals who need consistent overcurrent protection without compromising on space or ease of use.
