What is an overload contactor
A contactor is a large relay, usually used to switch current to an electric motor or another high-power load.
Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts.
What is NO and NC In Contactor?
NO is normally open i.e. the contacts are normally open and close when the switch is actuated. NC is normally closed i.e. the contacts are normally closed and open when the switch is actuated.
1NO1NC is generally used to describe contactors (industrial power relays) and manual switches like emergency stop buttons
