Residual current circuit breaker 3P+N 63A 30mA 10kA F CDF663D

Residual Current Circuit Breaker 3P+N – reliable installation protection

This three-pole residual current circuit breaker with an additional neutral pole (3P+N) with a rated current of 63A is designed to protect people and electrical installations against the effects of electric shock and fires caused by short circuits and earth leakage currents. A rated differential current of 30mA ensures a quick response in the event of a dangerous leakage, minimizing the risk of hazard. Short-circuit strength up to 10kA guarantees stable operation even in difficult conditions.

Construction and application

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement in electrical distribution boards. Its width of 4 modules allows for efficient use of space in the switchgear cabinet. Designed for operation in circuits with a rated voltage of 400V and a frequency of 50Hz, it will be suitable for both home and commercial installations. The use of characteristic F means that the circuit breaker reacts to sudden current surges with a certain delay, which is particularly important when connecting devices with electric motors or other inductive loads – this prevents unnecessary tripping.

Key features and benefits

• High reliability: Rated differential current of 30mA and high short-circuit strength (10kA) provide effective protection against electric shock and installation damage.
• Versatility: Suitable for use in both home and commercial installations thanks to the rated voltage of 400V.
• Easy installation: DIN rail mounting significantly speeds up the installation and replacement process.
• Safety of use: It has a lock preventing accidental switching on of the circuit breaker after switching off due to a failure.
• Wide operating temperature range: The ability to operate in a temperature range from -25°C to 70°C allows it to be used in various environmental conditions.
• Cable compatibility: Supports both solid (1…25 mm²) and stranded (1…16 mm²) wires, providing flexibility during installation.
• Expandability: The ability to connect additional equipment increases the functionality of the device.
• Compliance with standards: Meets the required safety standards, ensuring compliance with applicable regulations.

This circuit breaker is a solid solution for every installer and user looking for reliable electrical protection. Its technical parameters guarantee safe and efficient operation of the electrical installation for a long time.
