I work with heated 3phase presses with several heating elements being controlled by the same 50a 3p contactor. I'm using Definite Purpose Contactors and when the press reaches desired temp the contacts open. They stay constantly opening and closing to keep temp at set point. Sometimes they sound like they are arcing when closing. My question is am i using the right type of contactors for this type of activity? Are there different types of relays or other means of controlling the elements?
