Residual current circuit breaker RKN series 2P 25A 300mA RKN 2P 25A 300mA RKN 2P 25A 300MA

Residual Current Device (RCD) from the RKN series provides reliable protection for electrical installations, protecting against the effects of short circuits and electric shock. The 2P 25A model with a differential current of 300mA is a universal solution, suitable for both home and industrial installations. Designed for mounting on a DIN rail, it provides a quick response in the event of a dangerous leakage current.

Protection and safety

This Class A RCD is characterized by high efficiency in detecting leakage currents, minimizing the risk of electric shock. Class A means that it is particularly effective in detecting DC currents, which can be generated by some electronic devices. The rated current of 25A allows for the protection of circuits with medium loads, and the sensitivity of 300mA provides adequate protection without excessive false tripping. The rated breaking capacity reaches 1.5kA – this is an important parameter for installations requiring high resistance to overloads.

Installation and application

The RKN 2P 25A 300mA RCD is designed for mounting on a DIN rail, which simplifies and speeds up installation. Its compact dimensions (2 modules) allow for saving space in the distribution board. It can be used in circuits with a rated voltage of 230V AC and a frequency of 50Hz. This makes it suitable for protecting lighting, electrical outlets and other electrical devices in residential, commercial and industrial buildings. The electromagnetic tripping mechanism ensures reliable operation even with voltage fluctuations.
