RC Snubber - voltage spike filter

RC Snubber – Anti-surge voltage filter for inductive loads

Protect your Shelly devices and improve the reliability of your installation.

Are you installing Shelly 1, 1PM, 2.5, or EM with fans, motors, or contactors? Then this component is essential.
The RC Snubber is designed to suppress voltage spikes generated by cutting inductive loads, preventing damage and malfunctions to your smart devices.

What exactly does the RC Snubber?

When you turn off a motor, fan, transformer, or any load with a coil, a voltage spike is generated that can damage your Shelly. The RC Snubber absorbs this spike and protects the internal relays , extending the life of your home automation system.

Compatible with :

• Shelly 1 / 1 PM

• Shelly 2PM

Especially recommended if you control inductive loads using contactors .

How do I install it?

Connect it in parallel , between the Shelly relay output and the neutral .
Locate it as close as possible to the inductive load (motor, fan, etc.) for maximum efficiency.

Frequently used applications:

• Ventilation motors

• Motorized blinds

• Air-conditioning

• Washing machines and dryers

• Refrigerators and cold storage rooms

• Transformers and ballasts

• High voltage LED drivers

Key Benefits:

• Avoid power surges that can damage your Shelly

• Improves system performance and stability

• Quick and easy installation

• Recommended by Shelly for inductive loads

Do you need it?

If you control inductive loads with any compatible Shelly device, yes, you need it.
Always consult your Shelly's manual to ensure proper installation.
