I have a relay that is rated for 5 amps, but there are three pairs of contacts that this 5A can go through. Say I wanted to max it out and run 5 amps through it. Do I have to be using all three sets of contacts, or can I run 5A through just one pair?

You may also find this interesting Relay contact rating
