Earthleakage Circuit Breaker (ELCB) of Rdm1L

Application
RDM1L series rediual current circuit breaker,is mainly applied to the distribution circuit of AC 50Hz,rated working voltage is 400V,rated current up to 800A for providing protection indirectly and prevent the fire caused by the fault gounding current,and it also can be used for power distribution and circuit protetion against overload and short-circuit,it also works for transfering circuit and starting motor unfrequently.
This production also is suitable for isolation.
This production conforms to the standard 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.
3.4 Class of pollution: 3 Calss
3.5 Maximum install inclined angle: 5°,it should be installed at the place without obvious impact and weather-influence.
3.6 Main circuit installation type:III
Auxiliary circuit and control circuit installation type:II
3.7 External magneticfield of installation location should be exceed than 5 times of earth magnetic field.
3.8 Installation electromagnetic environment:B type
