[PSUBS-MAILIST] relay's

[hank pronk via Personal_Submersibles]

Hi Sean,Thanks' , I was thinking to use 12 v to activate the relay and run 36v through the load side.  I just want to be sure the relay rated at 30\40 A at 12 V can handle 20A at 36 V on the load side.   So my amp draw is less than rated but my voltage is higher than rated.Hank

 You can't necessarily use a relay at higher than designed voltage. The coils are specific to a particular voltage and type (AC / DC).   On the load side, you can use any voltage and current within the rated maximums.Sean

Hi All,I have some 30\40 amp 12 volt relays, what would the rating be at 36 volts.  Would they still be at 30\40 amp or 1\3 that.Hank
