Residual current circuit breaker 1P+N 63A 30mA 6kA AC CDC263J

Safety and reliability in your installation

This 1P+N residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. Designed to operate at 230V, it offers a rated current of 63A and a sensitivity of 30mA, guaranteeing a quick response in the event of a leakage current. Its construction based on AC technology provides effective protection against electric shock.

This circuit breaker is used in both new and modernized electrical installations – in homes, apartments, workshops or offices. Installation is on a DIN rail, which simplifies and speeds up the installation process. Compact dimensions (2 module width) allow for efficient use of space in the distribution board.

Functionality and technical parameters

The circuit breaker is characterized by high resistance to shock current (0.25 kA) and short-circuit withstand up to 6 kA, ensuring its reliable operation even in difficult operating conditions. The rated impulse withstand voltage Uimp is 4 kV, and the rated insulation voltage Ui is 500 V. This makes the device resistant to overvoltage and provides long-term protection of the installation.

Key parameters allow for optimal adaptation to the needs of the installation: the rated current of 63A provides sufficient power for circuits with higher demand, and the sensitivity of 30mA guarantees a quick response and effective protection against electric shock. The short-circuit withstand of 6 kA ensures stable operation even under high loads. DIN rail mounting is a standard that facilitates installation and replacement, and the compact width of 2 modules saves space in the distribution board. The device maintains full functionality in a wide temperature range from -25°C to +40°C.

In addition, the circuit breaker has a protection degree of IP20, which protects against accidental contact and the ingress of solid objects larger than 12.5 mm. The possibility of additional equipment allows you to adapt the device to individual installation needs. Power losses are 8.1 W at a frequency of 50 Hz. The connectable conductors can have a cross-section from 1 to 25 mm² (solid) or from 1 to 16 mm² (stranded). The device does not have a lock, which facilitates its operation during maintenance or repair of the installation.
