Star-Delta Starter

Star-Delta Starter Star-Delta Starter

QJX4-d range star-delta starter is designed for starting current control of a three phase squirrel cage induction motor. If equipped with compatible thermally relay, it can be used to protect the motor against overload and phase breaking. The product is not designed for reverse conversion or AC-4 utilization category applications. The starter is composed of three AC contactors, one air time delay terminal, and one auxiliary contact terminal (QJX4-40d or lower types) which are mounted on one baseplate.
