Product Introduction

The QC30 series electromagnetic starter is suitable for starting and stopping three-phase squirrel cage motors with an AC frequency of 50Hz (60Hz), a rated voltage of 380V, and a rated current of 12A under the AC3 category. The electromagnetic starter has overload and phase loss protection functions, and can be equipped with a float switch to automatically control the liquid level. Its internal components adopt LC1-D series contactors and LR1-D series thermal relays produced by the French company "TE", which have the characteristics of small size, light weight, and reliable protection.
