Eaton FAZ-C16/3N Miniature Circuit Breaker, 3+N Poles, C Curve, 16A, 15kA

The Eaton FAZ-C16/3N is a professional-grade miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This device is specifically designed to safeguard installations against the risks of overloads and short circuits, ensuring consistent performance and safety. With its 3+N pole configuration, it offers comprehensive control over three-phase systems with a neutral connection, making it a versatile component for modern electrical distribution boards.

Advantages

This circuit breaker stands out due to its high breaking capacity of 15kA, which allows it to handle significant fault currents without compromising the integrity of the electrical system. The C-type tripping characteristic provides an optimal balance between sensitivity and operational reliability, preventing nuisance tripping during standard motor or lighting start-ups while reacting quickly to genuine electrical faults. Its compact design facilitates easy integration into standard DIN-rail mounting systems, saving valuable space in distribution cabinets.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Protection of three-phase motors and equipment
• General electrical infrastructure requiring neutral switching

When it may not be suitable

This device is not intended for residential applications where a lower breaking capacity is sufficient and cost-effectiveness is prioritized over high-performance fault handling. It is also not suitable for circuits requiring different tripping characteristics, such as B-curve for purely resistive loads or D-curve for high-inrush current equipment.

Key specifications

• Rated current: 16A
• Number of poles: 3+N
• Tripping characteristic: C-curve
• Breaking capacity: 15kA
• Mounting type: DIN-rail

How to use

The Eaton FAZ-C16/3N should be installed by a qualified electrician within a suitable distribution enclosure. The device is designed for snap-on mounting onto a standard 35mm DIN rail. Ensure that the supply cables are connected to the appropriate terminals according to the wiring diagram provided on the device housing. Tighten all terminal screws to the specified torque to prevent overheating and ensure a secure electrical connection.

What to consider before purchase

• Verify that the 16A rating matches the requirements of your specific electrical load.
• Ensure the 3+N configuration is compatible with your existing distribution board layout.
• Confirm that the 15kA breaking capacity meets the safety standards required for your installation site.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to test the mechanical operation of the switch periodically to ensure it remains functional. Always disconnect the power supply before performing any maintenance or inspection on the electrical panel.
