Hello. I require a relay which can switch 72VDC. DC is the important part. As most seem to maxc out a 30VDC as I know its harder to switch. So my setup is Arduino Leonadro, 5V switching signal to the Relay. The Relay then switches a 72VDC load on/off. Just for 50ms. The current is also very low …

Higher voltage DC relay

@kmin has a good suggestion, I have used them with great success. Be sure to pick the FR120N-100V 9.4A.
