Eaton FAZ C40/3N Miniature Circuit Breaker 3P+N 40A 15kA

The Eaton FAZ C40/3N is a professional-grade miniature circuit breaker engineered to provide robust protection for electrical distribution systems. With a 3P+N configuration, this device is capable of monitoring and safeguarding three-phase circuits with a neutral connection, ensuring comprehensive coverage against electrical faults. Its high breaking capacity of 15kA makes it an ideal choice for demanding environments where reliability and safety are paramount.

Advantages

This circuit breaker offers exceptional durability and consistent performance under various load conditions. The C-curve tripping characteristic provides a balanced response to overcurrents, making it suitable for a wide range of industrial and commercial applications. Its compact design allows for efficient use of space in distribution boards, while the high-quality construction ensures long-term operational stability and protection against short circuits and overloads.

Suitable for

• Industrial electrical distribution panels
• Commercial building power systems
• Three-phase motor protection
• General electrical infrastructure requiring high breaking capacity

When it may not be suitable

This device is not intended for residential applications where a lower breaking capacity or single-phase protection is sufficient. It is also not suitable for circuits requiring different tripping characteristics, such as B-curve for sensitive electronics or D-curve for high-inrush current equipment.

Key specifications

• Rated current: 40A
• Number of poles: 3P+N
• Breaking capacity: 15kA
• Tripping characteristic: C-curve

How to use

The Eaton FAZ C40/3N is designed for mounting on a standard DIN rail within an electrical enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply voltage matches the device ratings and that all terminal connections are tightened to the specified torque to prevent overheating or poor contact.

What to consider before purchase

• Verify that the 40A rating matches your circuit load requirements.
• Ensure the 15kA breaking capacity is appropriate for your installation's prospective short-circuit current.
• Confirm that the 3P+N configuration is compatible with your existing wiring setup.

Usage recommendations

Regular inspection of the circuit breaker and periodic testing of the installation are recommended to ensure continued safety and performance. Do not exceed the rated current capacity to avoid nuisance tripping or potential damage to the device.
