IEC motor starters are a combination of contactors and overloads used to operate polyphase induction motors and protect them against running or stalled overcurrents, and feature components that meet IEC design standards. These components offer convenience and cost-effectiveness in one package, with capacities up to 38A.
IEC compliant magnetic motor starters are available as open frame starters or as enclosed manual motor starters. Open frame starters include a contactor, overload relay and auxiliary contacts. Enclosed manual motor starters include a contactor, overload protection, and auxiliary contacts.
