Energy absorbing circuits are used to suppress the voltage spikes caused by the inductance of the circuit when an electrical or mechanical switch is opened.
To be used for all Shelly relays that restart when switching on induction loads such as fans, motors, rollers or those that cause voltage spikes when switched on.
The RC snubber should be wired between the output and the circuit neutral.
