Using RC Snubbers on Shelly Pro 3 Smart Switch, Switching 240v Feed to MW Power supplies?

[KHill9314]

Hi all, just chasing some opinions from anyone who has used Shelly or other smart relays to control 240v feeds to their power supplies.

Would the inrush current from normal LRS 350 12 power supplies warrant the use of an RC Snubber on each smart relay channel (Will only be a max of 2 supplies on each channel)?

Cheers,

I don't use anything on my control (CBus Relays) - one box has 2x 350W PSUs, another has a 400W + 1.2kW PSU on the same switch.
No issues.

I am used Shelly 1PM Plus smart relays on all my controller boxes. No need to add anything extra to it. I'm using 2x LRS-600 12 power supplies on each relay. Worked really well last year
