Product Detail
YD2300 Series Intelligent Motor Protector are practical protectors to prevent damages to motors caused by short circuit, overloa

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.
