Residual current circuit breaker 3P+N 63A 300mA 6kA Type A CFA463J

### Safety and protection in your installation

Residual Current Device (RCD) 3P+N 63A 300mA is a key element ensuring safe operation in electrical installations. This device, manufactured by Hager, effectively protects against electric shock and the effects of leakage currents, which is particularly important in three-phase installations. Its function is to quickly disconnect the circuit in the event of a fault, minimizing the risk of damage and danger to life.

Functionality and technical parameters

This four-pole (3P+N) RCD with a rated current of 63A and a sensitivity of 300mA is characterized by its high efficiency. It has a short-circuit breaking capacity of up to 6kA, which guarantees its reliability even in the event of high overvoltages. DIN rail mounting simplifies and speeds up installation, and compact dimensions (4 modules wide) allow for efficient use of space in the distribution board. Rated voltage of 400V and insulation voltage Ui of 500V ensure safe operation under standard conditions.

For installers and end users

This RCD is an ideal solution for both professionals involved in electrical installations and end users who care about safety in their homes or businesses. A wide range of wire cross-sections (1-25 mm² for solid and 1-16 mm² for stranded) ensures compatibility with various types of cabling. Additionally, the possibility of mounting additional equipment allows the RCD to be adapted to the specific needs of a given installation. The degree of protection IP20 means protection against touching with fingers and solid objects larger than 12.5 mm – standard protection inside the distribution board enclosure.

Good to know: Characteristic A means that this RCD is particularly recommended for use with electronic devices that may generate small leakage currents. It provides effective protection without unnecessary tripping caused by interference.
