Shelly 1 v3 - Electric flash when turning off device?

    • Autor

    Hi,

    Im fairly new to Shelly, but I installed a Shelly 1 in between an electric heater following the wiring diagram I found online here:

    (Note I didnt split cables Shelly like in the image but with a 3 wire Wago):

    Der Inhalt kann nicht angezeigt werden, da Sie keine Berechtigung haben, diesen Inhalt zu sehen.

    Now everything works fine, including the heater. But I noticed when I turn off Shellys relais to the heater I can see a white flash happening inside in the gap next to the screws.

    Im just wondering if this is normal?

    The heater is 2000 watts, which is according to my calculations on 230 volt way under Shellys limit.

    Kind regards,

    Riz

    It is well in the limits, yes. That doesn't mean it will live a long life...

    There are peak currents and so forth.

    Anyway, at these levels sparks should not be a surprise and hence it is (in my humble opinion) much better to use heavier gear than that very tiny switch.

    But if you like it... by all means. It's only my opinion.
