Notes: - Check coordination tables for proper selection of Breaker and Line contactor. - Control Voltage and Control Input voltage are from same source in above example. Please check manuals if you have different sources for Control Voltage and Control input Voltage. - Semiconductor Fuses “F” are only required for Type 2 coordination. Please check coordination tables - ASTAT XT Soft Starter can operate without line contactor, however the use of a line contactor will increase the operation safety, and provide a way to switch off the Breaker in case of an emergency.
