Contactor vs. relay

  1. Jan 22, 2005 #1
    I don't see the difference between a contactor and a relay. Can anybody tell me what the difference is, when to use a relay over a contactor ?
    What are some criterias that need to be taken into consideration when choosing a contactor ?

    it looks like a contactor is a relay capable of large amt. of amps..
