Combined residual current circuit breaker with overcurrent protection series RKP 1P+N 25A characteristic B residual current 30mA RKP 1P+N B25A 30mA RKP 1P+N B25A 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. The device combines the functions of an overcurrent circuit breaker and a residual current device, protecting against the effects of overloads, short circuits and electric shock. This model, with a rated current of 25A and B characteristic, is perfect for both home installations and public utility facilities.

Functionality and application

RKP 1P+N circuit breaker with a residual current of 30mA provides a quick response to dangerous leakage currents to earth. A residual current of 30mA is the recommended value for protecting people in electrical circuits. Characteristic B means that the circuit breaker reacts quickly to overloads, but allows for short-term current exceedances without unnecessary tripping – which is important, for example, when starting devices with electric motors. This will avoid unplanned downtime caused by false alarms.

This circuit breaker is used to protect lighting circuits, socket circuits and electrical devices requiring protection against electric shock. Its compact size (width 17.8 mm) allows for easy installation in standard distribution boards.

Construction and parameters

RKP 1P+N circuit breaker is made of high-quality materials, which guarantees its reliability and long life. It meets the requirements of IEC/EN 61009-1 standard, confirming its compliance with European safety standards. The device is designed to operate at ambient temperatures from -5°C to +40°C, making it a universal solution for various installation conditions. The circuit breaker allows connection of conductors with a cross-section from 1 to 16 mm², which ensures compatibility with most typical electrical installations.
