I got this relay. In the product description they say: "belastet bis zu 10 Amp/250 VAC, 5 Amp 30 VDC." which means: "charged up to 10 amp / 250 VAC, 30 VDC 5 Amp".

On the relay it is printed: 10A/125V~

I would say that the description is not the same. Can I use it to switch on and off devices that are using 230V?

Thank you for your help.


No. Always trust component markings before product descriptions, especially if you got the component from a dubious source (and yes, amazon counts as a dubious source in this context).

  • \$\begingroup\$ no, don't trust markings, check the data sheet, you might find that the markings specify a usage that gives a very short life. \$\endgroup\$ – Jasen Mar 20 at 1:45


Sometimes the product markings don't cover all the device's capabilities. see if the manufacturer has provided more information in the datasheet.

Panaonic JS1 series relay datasheet: https://www.alliedelec.com/m/d/eb12058a03bad44415c80ace65c84066.pdf

The data-sheet claims 277VAC capability, but this is excluded from the operating area graph on page 3. perhaps contact Panasonic for guidance.
