Eaton FAZ-C20/1-DC Miniature Circuit Breaker, 1-Pole, Type C, 20A

The Eaton FAZ-C20/1-DC is a high-performance miniature circuit breaker specifically engineered for direct current (DC) electrical systems. This 1-pole device is designed to provide robust protection against overcurrent and short-circuit conditions, ensuring the safety and operational integrity of industrial and commercial electrical installations. With a rated current of 20A and a Type C tripping characteristic, it offers reliable performance in demanding environments where precise circuit management is essential.

Advantages

This circuit breaker stands out due to its specialized design for DC applications, which requires different arc-extinguishing capabilities compared to standard AC breakers. Its compact miniature design allows for efficient use of space in distribution boards and control panels. The Type C tripping characteristic provides a balanced response, making it suitable for circuits with moderate inrush currents, such as those found in lighting or small motor applications. The robust construction ensures long-term durability and consistent protection under continuous load conditions.

Suitable for

• Industrial DC power distribution systems
• Commercial electrical control panels
• Protection of DC-powered machinery and equipment
• Photovoltaic system sub-circuits

When it may not be suitable

This device is specifically designed for direct current applications and should not be used in standard AC electrical circuits. Furthermore, it is not intended for high-inrush current applications that require a Type D tripping characteristic, nor is it suitable for environments exceeding its specified voltage or short-circuit breaking capacity limits.

Key specifications

• Rated current: 20 A
• Number of poles: 1
• Tripping characteristic: Type C
• Application: DC circuits
• Device type: Miniature circuit breaker

How to use

The Eaton FAZ-C20/1-DC is designed for installation on standard DIN rails within an electrical enclosure. Before installation, ensure the power supply is completely disconnected. The device should be mounted by snapping it onto the rail and securing the electrical connections according to the terminal capacity specifications. Ensure that the wire gauge used is appropriate for a 20A current rating to prevent overheating. Once installed, the breaker can be toggled manually to control the circuit, and it will automatically trip in the event of a fault.

What to consider before purchase

• Verify that your system operates on DC voltage rather than AC.
• Ensure the 20A rating matches the requirements of your specific load.
• Check the available space in your distribution board for a 1-pole module.
• Confirm that the Type C characteristic is appropriate for your connected equipment.

Usage recommendations

Always ensure that the circuit breaker is installed by a qualified professional in accordance with local electrical codes and safety regulations. Regularly inspect the connections for tightness and ensure the device is free from dust or moisture accumulation to maintain optimal performance.
