Power Connection with Star-Delta Connection Kits
Overview
Star-Delta connection kits can be used for the power connections of the three contactors. If using the connection kits, the three contactors must be fitted with a cable memory or must be without cable memory.
Star-delta connection kits are made of three coupling bars:
-
the line-delta coupling bar, to couple the line and delta contactors with identical ratings
-
the star-delta coupling bar, to couple the star and delta contactors. The star-delta coupling bar and the line-delta coupling bar are identical when the star and delta contactors have identical ratings.
-
the star coupling bar to couple the motor stator windings.
The table below provides the list of the star-delta connection kits:
