Eaton FAZ-C10/2-DC Miniature Circuit Breaker, 2-Pole, C-Characteristic, 10A, 10kA, DC

The Eaton FAZ-C10/2-DC is a high-performance 2-pole miniature circuit breaker specifically engineered for direct current (DC) electrical systems. This device provides essential protection against overloads and short circuits, ensuring the safety and operational integrity of sensitive equipment in industrial and commercial environments. With its robust construction and precise tripping mechanism, it serves as a reliable component for managing DC power distribution.

Advantages

This circuit breaker offers superior reliability due to its specialized design for DC applications, which often present unique challenges compared to AC systems. The C-characteristic ensures an optimal balance between sensitivity and resistance to nuisance tripping during temporary current spikes. Its high breaking capacity of 10kA provides significant protection even in systems with high fault current potential, while the 2-pole configuration allows for the simultaneous disconnection of both poles, enhancing overall system safety.

Suitable for

• Industrial DC power distribution systems
• Commercial automation and control panels
• Photovoltaic (PV) system installations
• DC motor protection and control circuits
• Uninterruptible power supply (UPS) systems

When it may not be suitable

This device is specifically designed for direct current (DC) applications and should not be used in standard alternating current (AC) circuits, as the internal arc quenching mechanisms differ significantly. It is also not intended for high-voltage transmission lines or residential circuits that require specific AC-rated protection devices.

Key specifications

• Number of poles: 2
• Rated current: 10A
• Tripping characteristic: C
• Breaking capacity: 10kA
• Application type: DC

How to use

The circuit breaker is designed for mounting on a standard DIN rail within an electrical distribution board or control cabinet. Ensure that the power supply is completely disconnected before installation. Secure the device firmly onto the rail and connect the DC supply lines to the appropriate input terminals and the load lines to the output terminals, ensuring that the polarity is observed according to the markings on the device. Once installed, verify all connections for tightness and proper contact before restoring power.

What to consider before purchase

• Verify that the system voltage does not exceed the rated limits of the device.
• Ensure the 10A current rating matches the requirements of your specific load.
• Confirm that the installation environment meets the necessary temperature and humidity standards.
• Check that the DC polarity is compatible with your circuit layout.

Usage recommendations

Always consult with a qualified electrician or electrical engineer when installing or modifying DC power circuits to ensure compliance with local safety regulations and standards.
