Eaton FAZ-C25/3N Miniature Circuit Breaker, 3+N Poles, C Curve, 25A, 15kA

The Eaton FAZ-C25/3N is a high-performance miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This device features a 3+N pole configuration, allowing for the simultaneous switching of three phases and the neutral conductor, which is essential for comprehensive circuit management. With a rated current of 25A and a high breaking capacity of 15kA, this circuit breaker is designed to handle significant electrical loads while ensuring safety against short circuits and overloads.

Advantages

This circuit breaker offers exceptional reliability and durability, making it a preferred choice for professional electrical installations. The C-type tripping characteristic provides a balanced response to current surges, preventing nuisance tripping during normal operation while reacting quickly to genuine faults. Its compact design allows for efficient use of space in distribution boards, and the high breaking capacity ensures that the device can safely interrupt high fault currents, thereby protecting downstream equipment and wiring from damage.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Protection of motor circuits and lighting installations
• Three-phase power supply networks requiring neutral switching

This device may not be suitable for residential applications where a lower breaking capacity is sufficient and the 3+N configuration is not required. It is also not intended for use in environments with extreme moisture or corrosive gases without appropriate protective enclosures.

Key specifications

• Rated current: 25A
• Number of poles: 3+N
• Tripping characteristic: C-curve
• Breaking capacity: 15kA
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed to be snapped onto a standard DIN rail within a distribution board. Ensure that all wire connections are tightened to the manufacturer's specified torque settings to prevent overheating and ensure a secure electrical contact.

What to consider before purchase

• Verify that the 25A rating matches your circuit load requirements
• Ensure the 3+N configuration is compatible with your specific wiring system
• Check that the available space in your distribution board accommodates the physical dimensions of the unit
• Confirm that the 15kA breaking capacity meets the fault level requirements of your installation

Usage recommendations

Regularly inspect the circuit breaker for signs of thermal damage or loose connections. Test the device periodically to ensure the mechanical tripping mechanism remains functional and responsive.
