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.
