Eaton FAZ C8/3 Miniature Circuit Breaker, 3-Pole, 8A, 15kA, C-Curve

The Eaton FAZ C8/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection against overcurrents and short circuits in diverse electrical installations. This device is designed to maintain high operational safety and system reliability, serving as a critical component in modern power distribution networks. With its precise engineering, it ensures that electrical circuits remain protected under demanding conditions, preventing damage to connected equipment and infrastructure.

Advantages

This circuit breaker stands out due to its high breaking capacity of 15kA, which allows it to handle significant fault currents effectively. The C-curve tripping characteristic is specifically optimized for applications involving inductive loads, where temporary high inrush currents are common. Its 3-pole configuration makes it ideal for three-phase systems, providing comprehensive protection across all phases simultaneously. The robust construction ensures long-term durability and consistent performance in both industrial and commercial environments.

Suitable for

• Industrial power distribution systems
• Commercial building electrical panels
• Protection of motors and transformers
• Lighting circuits with high inrush currents
• Control and automation equipment

This device may not be suitable for residential applications where a lower breaking capacity is sufficient or where space constraints in standard consumer units make a 3-pole device unnecessary. It is also not intended for use in DC circuits unless specifically rated for such applications, as its primary design focus is on AC power distribution.

Key specifications

• Number of poles: 3
• Rated current: 8A
• Tripping characteristic: C-curve
• Breaking capacity: 15kA
• Mounting type: DIN rail

To install the Eaton FAZ C8/3, ensure the power supply is completely disconnected from the distribution board. The device is designed for standard DIN rail mounting; simply snap the breaker onto the rail until it clicks into place. Connect the incoming power lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque settings to prevent overheating.

What to consider before purchase

• Verify that the 8A rated current matches your circuit load requirements
• Ensure your distribution board has sufficient space for a 3-pole device
• Confirm that the C-curve characteristic is appropriate for your specific load type
• Check that the 15kA breaking capacity meets the safety requirements of your electrical installation

Usage recommendations

Always consult with a qualified electrician for the installation and maintenance of circuit protection devices to ensure compliance with local electrical codes and safety standards. Regularly inspect the breaker for signs of wear or thermal damage to maintain optimal system performance.
