Shelly RC Snubber - Noise Suppressor

The Shelly RC Snubber is an accessory used to stabilize smart home circuits. It prevents electrical interference and switching issues when using smart relays with inductive loads. Inductive devices often generate voltage spikes during switching, which can cause lights to flicker or system glitches; this suppressor dampens those electrical transients, absorbing excess energy to improve the reliability of your automation setup.

The device measures 27 x 17 x 8 mm, allowing it to fit into standard backboxes or junction enclosures. At just 0.05 g, it adds negligible weight to the installation. It is designed for installers and users who need to resolve interference issues without changing their existing wiring. Connected in parallel, the component protects connected hardware from electrical surges.

• 600 V rating: suitable for standard household circuits.
• 100 Ω impedance: provides the resistance required to dampen transient interference.
• Parallel wiring: connects across the load, rather than in series with the relay.
• Hardware compatibility: works with contactors, LED drivers, transformers, motors, and refrigeration equipment.
