DC overcurrent circuit breaker 1-pole FAZ-C20/1-DC 279129

DC Overcurrent Circuit Breaker – Reliable Installation Protection

This single-pole circuit breaker from Eaton’s FAZ series, designed for direct current (DC) operation, is a robust solution for installations requiring effective protection against overloads and short circuits. A rated current of 20A combined with a breaking capacity of 10kA at 400V (and 10kA at 230V) guarantees safe operation in various applications. Characteristic C ensures that the circuit breaker reacts with a delay to short-term current surges, which is particularly important when starting devices with motors or other inductive loads.

Construction and Application

The FAZ-C20/1-DC circuit breaker is mounted on a TS 35 rail and is characterized by its compact dimensions – it occupies only one module in width. The IP20 degree of protection provides protection against accidental contact, increasing safety. Designed to operate at temperatures from -25°C to 75°C, it will perform well both indoors and outdoors (in building and overhead distribution boards up to an ambient temperature of 25°C). The possibility of subsequently adding accessories expands the functionality of the device, adapting it to the individual needs of the installation.

Key Features and Benefits

• Overload and Short Circuit Protection: Provides effective protection of electrical circuits against damage caused by excessive load or short circuit.
• Characteristic C: Ideal for circuits powering devices with high inrush current, such as motors or transformers. Allows you to avoid unnecessary tripping of the circuit breaker when starting these devices.
• Breaking Capacity 10kA: Guarantees safe disconnection of the circuit in the event of a short circuit with high energy.
• Compact Dimensions: Occupies only one module on a TS 35 rail, saving space in the distribution board.
• Expandability: The ability to mount additional accessories allows you to adapt the functionality of the circuit breaker to specific installation requirements.
• Wide Operating Temperature Range: Enables use in various environmental conditions.
• Contact Position Indicator: Facilitates visual control of the circuit breaker status (on/off).
• Suitable for conductors with a cross-section of 1…25 mm²: Ensures compatibility with various types of installation cables.

Thanks to these features, the FAZ-C20/1-DC circuit breaker is a reliable and versatile solution for both professional installers and end-users looking for safe and effective protection of their DC-powered electrical installations.
