Residual current circuit breaker RKN series 4P 40A residual current 100mA RKN 4P 40A 100mA RKN 4P 40A 100MA

Safety and reliability in your installation

Residual Current Device (RCD) RKN 4P 40A 100mA is a key element ensuring the protection of people and electrical devices against the effects of short circuits and leakage currents. The device is intended for use in circuits with a voltage of 230/400V AC, and its rated current of 40A makes it ideal for protecting various loads. The four-pole (4P) design allows protection of the entire circuit, including the neutral conductor.

Protection tailored to your needs

The RCD's differential current of 100mA ensures a quick response in the event of a dangerous leakage current to earth. This is particularly important in rooms with high humidity or exposed to contact with water. The RKN RCD has been designed with a wide range of applications in mind – from home installations, through commercial buildings, to industrial facilities. Thanks to this, you can be sure that your installation is protected regardless of its purpose.

Installation and operation

The RKN RCD is mounted on a standard 35mm DIN rail, which simplifies and speeds up installation. The compact dimensions of the device allow you to save space in the distribution board. The RCD is characterized by a high short-circuit strength of 6kA, which guarantees its reliable operation even in the event of serious disturbances in the electrical network. In addition, the device meets the requirements of IEC/EN 61008-1 standard, confirming its compliance with applicable safety standards. The possibility of connecting conductors with a cross-section of up to 25mm² provides flexibility in choosing the appropriate connections.
