YD2300 Series Intelligent Motor Protector
YD2300 Series Intelligent Motor Protector, developed by YADA Electric Co., Ltd., is a practical protector with multi-functions for electrical appliances. With its revolutionary structure, the protector can be installed as the display part and the controlling part separated or composed, to prevent damage to motors ( 50Hz AC current, rating voltage 660V) caused by short circuit, overloading, block loading, phase loss/unbalance, over/under-voltage, current leakage, or zero sequence.
