Fuji CP31FM/5WD - 5A, Circuit Breaker

The Fuji CP31FM/5WD is a purpose-built 5A circuit breaker designed to guard electrical systems from overloads and fault currents. Engineered for reliable performance in demanding environments, this unit delivers precise, predictable overcurrent protection in panelboards, switchboards, control panels, and OEM equipment.

Ideal for industrial, commercial, and OEM applications where dependable protection and safe operation are critical in distribution panels and motor control centers, the CP31FM/5WD helps you protect wiring, devices, and downstream equipment from damaging current surges.

Why the CP31FM/5WD stands out

• Targeted 5A protection: The 5-amp rating provides protection tailored to smaller circuits, reducing nuisance trips while ensuring critical components stay safeguarded.
• Versatile installation compatibility: Designed to slot into panelboards, switchboards, control panels, and OEM equipment, simplifying procurement and integration across diverse systems.
• Robust, reliable protection for demanding environments: Built to deliver consistent performance in industrial settings, supporting safe operation of distribution panels and motor control centers.

How it protects your system

When circuit current exceeds the 5A rating, the CP31FM/5WD trips to interrupt the circuit. This rapid response helps prevent overheating of conductors, insulation damage, and potential equipment failure, reducing downtime and extending the life of your electrical infrastructure.

Practical use cases

• Protect a dedicated control circuit powering sensors and relays within an OEM control panel
• Safeguard a branch circuit in a distribution panel serving small motors or actuators
• Replace a failed breaker in existing switchboards without altering other protective devices

Installation and compatibility tips

Ensure the 5A breaker is compatible with your panel’s enclosure and terminal sizing, and follow standard electrical codes during installation. Use identical rating and type for replacements to maintain consistent protection characteristics. The Fuji CP31FM/5WD is designed to integrate smoothly with compatible Fuji distribution components, making upgrades straightforward and reliable.

For dependable overcurrent protection in your critical systems—from panelboards to motor control centers—the Fuji CP31FM/5WD 5A circuit breaker delivers precise protection where it matters most.
