NDCQ1 Series Tri-star Starter

● Product introduction

The NDCQ1 series of tri-star starters (hereinafter referred to as starters) have the AC 50Hz (or 60Hz) and the rated insulation voltage of 690V, and are mainly used for the three-phase squirrel-cage induction motor with the rated working voltage of 415A and the rated working current of 95A (phase current of the starter with the triangle connection) as well as the AC-3 utilization category and the control power no more than 80KW for controlling starting, running and stopping of the stator winding converting from star to triangle. They can be provided with thermal relays to perform the overload protection on the motor and its circuit operation (running).

◆ Direct action type for the action mechanism of the contactor and double breakpoints for the contact;

◆ The starter comprises three sets of AC contactors, one air delay head and one auxiliary contact set, which are installed on a bottom plate provided with the appropriate conductor.


NDCQ1 series of tri-star starter has obtained China Compulsory Certification (CCC) for products.
