HK2 series open type load switch, is applied to circuit of AC 50Hz,rated voltage single-phase 220V or 380V,rated current from 6A to 63A,rated impulse withstand voltage Uimp:4000V,rated insulation voltage Ui:380V,as manual unfrequently making and breaking circuit with load and protecting the low-capacity circuit against short-circuit.
Normal operational conditions and installation conditions
3.1 Temperater: no higher than +40ºC,and no lower than -50ºC
3.3 The relative humidity: no more than 90%,when mouth average temperature is +25ºC.
The condensation that happened because of temperature changes should be taken care.
And Installation location should have no exploresion danger, and no gas and conductive dust which can cause corrosion and insulation damage.
