What is the difference between contactors and starters?

If you have a starter then you have a contactor and overload coupled together. This is what is refer to as a starter when they are combined. A contactor is with out the overload coupled. When ordering a starter you will have options for different overloads to be used. We offer them with bimetallic type overloads that required heaters to be installed and are ordered as a separate line item along with the starter. We also offer Solid State overload relays that offer advance protection features and better accuracy then the bimetallic overload relays. The SSOL has no heaters to installed as they are offered with a overload dial with amperage range of a min-max current value to set for you motor. The SSOL relay offers phase loss and unbalance protection as standard. you can order them with Ground fault protection as well.
