What is the difference between In-line and Inside Delta Soft Starter Circuits?
The Altistart 48 connected in the motor supply line
The motor connection depends on the supply voltage, which in this example is a star connection.
The motor connection depends on the supply voltage, which in this example is a delta connection.
The Altistart 48 connected in the motor delta winding
ATS48***Q or ATS48***YS316 starters connected to motors with delta connections can be inserted in series in the motor windings. They are powered by a current which is less than the line current by a factor of SQRT 3, which enables a starter with a lower rating to be used.
