The Shelly RC interference filter is an accessory to the Shelly relays, the connection of which is recommended when inductive consumers are used. Examples of such consumers are electric motors, fans, vacuum cleaners, washing machines, transformer power supplies (LED, laptop, TV power supplies).

These can cause voltage fluctuations in the electrical network when they are switched on and off, and if the manufacturers of these devices containing magnetic coils have not properly resolved the attenuation of voltage fluctuations, they can cause problems in the electrical network. Such a problem phenomenon can be, for example, the switching on/off and restarting of the Shelly relays.

In order to avoid and prevent problems, a Shelly RC snubber (0.1 μF / 100 Ω / 1/2W / 600 V AC) i.e. an RC noise filter should be connected between the output and zero of the controlled circuits.

The purpose of the arc suppression circuit in the RC noise filter is that when we remove the current from the coil and the mains voltage still "bounces", this fluctuation is dampened by the energy absorbing circuit inside it. Also compatible with Shelly 1, Shelly 1PM, Shelly 2.5, Shelly Plus 1, Shelly Plus 1PM and Shelly Pro 4PM.
