Residual current circuit breaker, 1P+N, C characteristic, 20A, 6kA, 30mA, AC, instantaneous DS201 C20 AC30 2CSR255080R1204

Electrical installation protection – reliable RCBO (Residual Current Breaker with Overcurrent protection)

This 1P+N RCBO is a key safety element in any electrical installation. It provides comprehensive protection against the effects of overloads, short circuits and dangerous leakage currents, translating into safety for people and property. Its versatility makes it suitable for use in both domestic, commercial and industrial installations.

Functionality and parameters

The circuit breaker is characterized by a rated current of 20A and a C characteristic, which means it copes well with impulse loads – typical for devices with induction motors (e.g. refrigerators, washing machines). The short-circuit breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a failure. In addition, the built-in residual current device with a sensitivity of 30mA (AC type) protects against electric shock by detecting even small leakage currents to earth. A width of 2 modules allows for efficient use of space in the distribution board.

Installation and application

The circuit breaker is mounted on a DIN rail, which is standard in most electrical distribution boards. Designed to operate at temperatures from -25°C to 55°C and has a protection degree of IP20, which ensures its reliability in various environmental conditions. This circuit breaker is ideal for protecting circuits with a conductor cross-section from 0.75 mm² to 16 mm². At the same time, the disconnectable N pole increases the functionality and safety of the installation. Power losses of 5.7W minimize the impact on the energy efficiency of the system.
