Residual current circuit breaker 1P+N 63A 30mA 10kA AC CDC563J

Safety and protection in your electrical installation

The Hager CDC563J 1P+N residual current circuit breaker (RCCB) is a key element ensuring the safety of using the electrical installation. The device effectively protects against electric shock by detecting even small leakage currents to earth. Its use is essential in both new and modernized installations, guaranteeing a high level of protection for people and equipment.

This RCCB is designed to protect circuits with a rated current of 63A, with a sensitivity of 30mA. This means it reacts to leakage currents from as little as 30 milliamperes, providing a quick and effective protection. The short-circuit breaking capacity at 10kA (AC) guarantees safe disconnection of the circuit in the event of a short circuit.

Mounting and application

The circuit breaker is mounted on a DIN rail, which facilitates its installation and replacement. Compact dimensions (2 modules wide) allow for efficient use of space in the distribution board. Designed to operate at temperatures from -25°C to 70°C and has an IP20 protection degree, making it suitable for most standard operating conditions. It accepts wire cross-sections from 1 mm² to 16 mm² (multi-strand) and from 1 mm² to 25 mm² (solid core), providing flexibility when selecting wires. A mechanical lock prevents accidental disconnection of the circuit breaker, increasing safety.

• Applications:
  • Protection of lighting circuits
  • Protection of sockets in residential and public utility premises
  • Protection of electrical appliances with a power of up to 63A
  • Installations in residential, commercial and industrial buildings
• For installers: Quick mounting on a DIN rail, a wide range of accepted wire cross-sections make the work easier.
• For users: Provides a high level of safety and protection against electric shock.

Characteristics and parameters

The circuit breaker is characterized by high reliability and durability confirmed by certificates of compliance with IEC/EN standards. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 4kV, ensuring resistance to overvoltages. The device has a mechanical lock preventing accidental disconnection and the possibility of additional equipment (e.g. locks). AC execution means that the circuit breaker reacts to alternating currents with a frequency of 50Hz – standard in most European electrical installations. It is worth paying attention to the impulse withstand current of 0.25kA – a parameter important for ensuring the long-term reliability of the device in difficult operating conditions.
