Optional auxiliary / alarm contact blocks and additional poles mount on manual motor controller or disconnects to provide additional functions or connections.
Motor control devices encompass simple manual controllers, motor contactors and starters, drives and soft starters. For every motor, some form of electrical control is required, from simple ON/OFF to more complex variable speed applications.
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.
