Calmer switching for motors and fans.
What it does
Every time a relay switches off a motor, fan, transformer or LED driver, the load can throw back a sharp voltage spike. Over time that stresses the relay and can make switching unreliable. The Shelly RC Snubber is a 100 ohm resistor and a 0.1 µF capacitor in series, wired across the load, which gives that energy a safe path to dissipate.
Shelly lists inductive loads as supported on many of its relays on the condition that a snubber is fitted, so it is worth adding one wherever a relay drives a pool pump motor, an extractor fan or a ceiling fan. It has no electronics to set up and does not appear in any app; it simply sits across the load and does its job.
What you need
For use across an inductive load switched by a Shelly relay. It has no app and needs no network.
Install
This device is wired into your mains or DB board and must be fitted by a registered electrician.
A registered electrician must fit the snubber across the load, as close to the load as possible. The user guide for your Shelly relay says whether one is needed.

- Absorbs voltage spikes from inductive loads.
- Helps protect the switching relay and keep it reliable.
