Residual current circuit breaker RKN series 2P 40A 300mA RKN 2P 40A 300mA RKN 2P 40A 300MA

Protection of installations and people – Residual Current Device (RCD) RKN

The RKN 2P 40A RCD with a differential current of 300mA is a key element ensuring safety in every electrical installation. This device, manufactured by LS Electric, effectively protects against electric shock and also safeguards circuits against the effects of short circuits and overloads. It is an indispensable component in both residential and industrial buildings.

This two-pole (2P) circuit breaker with a rated current of 40A reacts to leakage currents with a value of 300mA. This means that in the event of detecting an irregularity in the current flow – e.g., when current "leaks" through the human body or damaged insulation – the circuit breaker automatically disconnects the power supply, minimizing the risk of hazard. The construction based on electromagnetic technology ensures reliable operation even with voltage fluctuations and loss of neutral.

Installation and application:

The RKN circuit breaker is mounted on a standard 35mm DIN rail, which facilitates its installation and replacement. The width of the device is 36mm (2 modules), which allows for efficient use of space in the distribution board. Thanks to the AC protection class, this circuit breaker is designed to detect sinusoidal alternating currents, making it an ideal solution for most standard electrical installations. The ability to connect wires with a cross-section of up to 25mm² ensures compatibility with various types of cabling.

Why choose the RKN circuit breaker?
