Residual current circuit breaker RKN series 4P 40A residual current 300mA RKN 4P 40A 300mA RKN 4P 40A 300MA

Residual Current Device (RCD) RKN 4P 40A is a key element ensuring safety in electrical installations. The device is designed to protect people and equipment from the effects of short circuits, overloads, and – most importantly – electric shock. This model, with a rated current of 40A and a differential current of 300mA, is used in both residential and industrial buildings.

The four-pole (4P) design ensures that the circuit breaker effectively protects the entire circuit, including the neutral conductor. This provides comprehensive protection against dangerous leakage currents. The differential current value of 300mA makes it suitable for applications where greater resistance to interference is required, while maintaining a high level of safety. The circuit breaker is characterized
