Application
RDL20 series Earthleakage circuit breaker, is applied to circuit of AC50Hz,rated operate voltage 380V,rated current from 16A to 630V,as protection against electric leakage of circuit and equipments.And it also can previde protection against the fire danger which is caused by equipment insulation damage.And this product also protect circuit agaisnt overload and short-circuit,and circuit unfrequently transfer.
This product conforms to the standards of IEC60947-2 and GB14048.2.
Normal operational conditions and installation conditions
3.1 Temperater: no higher than +40ºC,and no lower than -5ºC,and the day average temperature no higher than +35ºC.
3.2 Altitude: no higher than 2000m
3.3 The relative humidity: no more than 50%,when temperature is +40ºC.The product can withstand higher humidity under lower temperature,for instance,when it at +20ºC,the production can withstand 90% relative humidity.
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.
