Intelligent Motor Protector

Product Detailed

Intelligent Motor Protector 1.Prevent damages to motors caused by short circuit,overloading,block loading,current leakage etc.

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.

Feature

Model	Structure	Function & Feature
YD2301T	Integrated	² The motor protector replaces the thermal relay protection by adopting Normal Close Contact Output. ² The running of the protected motor will not be interrupted when the protector stopped due to power failure. ² RS485 module is optional.
YD2302T	The display part and the controlling part are separated
YD2301L	Integrated	² Multiple startup modes are available; current protection; ² RS-485 communication; ² One route DC4-20mA output (optional).
