DC overcurrent circuit breaker 1-pole FAZ-C4/1-DC 279124

DC circuit protection with FAZ-C4/1-DC circuit breaker

This single-pole circuit breaker from Eaton, model FAZ-C4/1-DC, provides reliable protection for DC-powered electrical installations. Designed to operate at 250V DC and a rated current of 4A, it effectively protects circuits from overload and short circuits. Its compact size – 1 module wide – allows for efficient use of space in the distribution board.

Construction and application

The FAZ-C4/1-DC circuit breaker features a C tripping characteristic, meaning it reacts more slowly to short-term current surges. This makes it ideal for circuits with devices with high inrush current, such as electric motors or switch-mode power supplies. The ability to add accessories later increases its functionality and allows it to be adapted to the specific needs of the installation. The circuit breaker is designed for mounting on a TH35 rail and has an IP20 degree of protection, ensuring safe operation under normal conditions.

Key features and benefits

• High breaking capacity: Rated breaking capacity up to 10 kA at 230V and 400V DC guarantees effective protection against the effects of short circuits.
• Versatility: Suitable for solid and stranded conductors with a cross-section from 1 to 25 mm², which facilitates its installation in various types of installations.
• Wide temperature range: Ability to operate at ambient temperatures from -25°C to 75°C ensures reliability even in difficult conditions.
• Contact position indicator: Red-green indicator allows for quick visual assessment of the circuit breaker status – whether it is on or off.
• Expandability: Three-position snap-on slider allows for easy removal and subsequent addition of additional accessories, increasing the functionality of the device.
• Safety: Compliance with IEC 60947-2 standard ensures a high level of safety.

The FAZ-C4/1-DC circuit breaker is a solid and reliable solution for both professional installers and end-users looking for effective protection of their DC-powered electrical installations. Its compact size and ease of installation make it ideal for commercial and domestic applications.
