Shelly RC Snubber Energy Absorbing Circuit

Shelly RC Snubber Energy Absorbing Circuit

The Shelly RC Snubber Energy Absorbing Circuit is designed to suppress voltage spikes produced when switching inductive loads. Its series-connected resistor and capacitor provide a short-term alternative path for current, helping the inductive load discharge and protecting sensitive components within a connected Shelly switching circuit.

Reliable Protection for Inductive Loads

Inductive equipment can produce a voltage spike when its switching circuit opens. The Shelly RC Snubber helps mitigate this spike, supporting the performance and reliability of compatible Shelly-controlled circuits.

Key Features:

• Suppresses voltage spikes caused by the switching of inductive loads.
• Combines a resistor and capacitor connected in series.
• Provides a temporary alternative current path so that the inductive load can discharge.
• Helps protect sensitive components in compatible Shelly switching circuits.
• Suitable for use with a range of motor-driven and inductive equipment.
• Designed to be connected in parallel with the inductive load.

Typical Applications:

The RC Snubber is commonly used when a Shelly device switches inductive loads such as:

• Fans
• Refrigerators
• Air conditioners
• Washing machines
• Tumble dryers
• Transformers
• LED light drivers
• Other equipment incorporating an electric motor

Installation Guidance:

The RC Snubber should be connected in parallel with the inductive load and positioned as close to the load as possible. Check the user guide for the relevant Shelly device to confirm whether an RC Snubber is required and follow its specified wiring instructions.
