Residual Current Device (RCD) series RKN 2P 63A 300mA RKN 2P 63A 300mA RKN 2P 63A 300MA

Safety and electrical installation protection

Residual Current Circuit Breaker (RCCB) RKN 2P 63A is a key safety element in every electrical installation. Its function is to quickly disconnect the circuit in the event of a ground fault current, minimizing the risk of electric shock and equipment damage. This model, with a rated current of 63A and a differential current of 300mA, provides comprehensive protection for both the installation and users.

Characteristics and application

The RKN 2P 63A 300mA circuit breaker is a two-pole (2P) device, which means it protects two phase conductors. The differential current of 300mA makes it particularly useful in circuits where devices generating small leakage currents are present, e.g. switch-mode power supplies or certain types of LED lighting. This reduces the risk of the circuit breaker tripping unnecessarily during normal operation. It is an ideal solution for protecting lighting circuits, socket outlets and electrical appliances in residential, commercial and industrial buildings.

Construction and installation

The RKN circuit breaker is characterized by a compact design (width 36mm – 2 modules), which facilitates its installation on a TH-35 rail in a distribution board. It ensures reliable operation thanks to the use of high-quality materials and precise manufacturing technology. The possibility of using comb connectors (PIN) facilitates and speeds up installation and ensures a secure electrical connection. The device meets the requirements of IEC61008-1 standard, which guarantees its safety and compliance with applicable regulations. Class AC means that the circuit breaker reacts to alternating currents with a sinusoidal waveform and to pulsating DC currents – this is important when protecting electronic devices.
