Application
KNR8 series overload relay is suitable for 50Hz/60Hz, rated voltage up 690~1000V,rated current 0.1~400A in main circuit of long time working. It is used to protect AC three-phase asynchronous motor against overload and open phase.
This products conformity with IEC947-4, VDE0660,GB14048.4 standards .
Working condifion
●The altituelde should be not higher than 2000m;
●The ambient temperature:-25℃~55℃;
●The relative humidity: when +25℃,the relative humidity of air should be not more than 90%.
Feature
●Senies overload relay of thermal metal mode, tripping class is 10A;
●Setting current continuous adjustable device;
●Trip indicator;
●Test button;
●Reset button by hand operation and automatic reset button;
●Have a pair of No and Nc insulation contact in electricity;
●Mode of installation: install independently or can plug in the AC contator.
