Eemeli Posted August 28 Share Posted August 28 Hello! I would like to connect the contactor with a separate switch if there is a fault sometimes in the Shelly. Is the connection shown in the picture ok? Quote Translate Revert translation?

tvbshelly Posted August 28 Share Posted August 28 (edited) Is there a reason why you are not using a contactor that has a built-in on/off/auto switch? eg. https://www.findernet.com/en/worldwide/series/serie-22-installationsschutze-25-40-63-a/type/typ-22-32-installationsschutze/ Edited August 28 by tvbshelly Quote Translate Revert translation?

tvbshelly Posted August 28 Share Posted August 28 Okay, I get it. It depends on what exactly you want to achieve. Your switch only solves the problem if you cannot switch on with the Shelly. If there was a problem with the Shelly switching off, the contactor with switch would be better. This type of contactor is available precisely for such cases - when the electrical switching path via A1/A2 fails. Quote Translate Revert translation?
