RC Snubber
Short description
The RC Snubber is a component that comprises a resistor (R) and a capacitor (C) connected in series. It effectively mitigates voltage spikes that can occur during the switching of inductive loads by providing a short-term alternative current path around the switching device, so that the inductive load is safely discharged. The RC Snubber can protect sensitive components of your Shelly device from voltage spikes and improve the overall performance and reliability of the connected circuits.
Main applications:
The RC Snubber finds common applications with inductive loads, such as:
Fans
Refrigerators
Air-conditioners
Washing machines
Tumble dryers
Transformers
LED light drivers
Other devices with electrical motors
Compatibility
If in doubt whether you need to install an RC Snubber or not, read carefully the User guide for your Shelly device. You can purchase the RC Snubber from our online shop.
You should connect RC Snubbers in parallel to inductive loads which you intend to switch with Shelly devices. Connect the RC Snubber as close to the inductive load as possible.
