Combined residual current circuit breaker with overcurrent protection series RKP 1P+N 20A characteristic C residual current 30mA RKP 1P+N C20A 30mA RKP 1P+N C20A 30MA

Safety and protection in your electrical installation

Combined residual current circuit breaker RKP 1P+N is a key element ensuring safety in every electrical circuit. It combines the functions of an overcurrent circuit breaker and a residual current device, offering comprehensive protection against overloads, short circuits and electric shock.

This model, with a rated current of 20A and characteristic C, is ideal for protecting lighting circuits, socket circuits and devices with a characteristic starting current.

How it works and where to use it?

The RKP 1P+N circuit breaker with a differential current of 30mA reacts quickly to earth leakage currents, cutting off the power supply when a dangerous situation is detected. A differential current of 30mA provides effective protection for people against electric shock. Characteristic C means that the circuit breaker allows for short-term overloads, which is particularly important when connecting devices with motors or transformers – it will not switch off with every short-term surge in power consumption. This makes it reliable in protecting circuits powering devices such as washing machines, refrigerators or pumps.

Design and parameters for professionals

The RKP 1P+N circuit breaker has a modular design, taking up 2 modules on a TH35 rail. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 4kV. The rated breaking capacity is 6kA, which guarantees effective circuit interruption in the event of a short circuit. The degree of protection IP20 provides protection against contact with fingers and solid objects larger than 12mm. The circuit breaker meets the requirements of EN 61009 standard. The cross-section of the connected single-wire and multi-wire cable is 1 mm².
