Thermal-magnetic circuit breaker RDM1L

residual currentdistributionmolded case

RDM IL sériés moulded case circuit breaker, is mainly applied to the distribution circuit of AC50/60Hz, rated working voltage is 400V,rated current up to 800A for providing protection indirectly and prevent the fire caused by the fault grounding current, and it also can be used for power distribution and circuit protection against overload and short-circuit, it also works for transfering circuit and starting motor unfrequently. This product is suitable for isolating. This product is applied to standard of IEC 60947-2. Normal opération condition and installation condition 3.1 - Temperature: no higher than +40 °C, and no lower than -5 °C ,and the average temperature no higher than +35°C. 3.2 - Installation location no more than 2000m. 3.3 - The relative humidity: no more than 50%, when Temperature is +40°C. The product can withstand the higher humidity under lower temperature, for instance, when temperature at +20°C, the product can withstand 90% relative humidity. The condensation that happened because of temperature changes should be taken care with spécial measurements 3.4 - Class of pollution : 3 Class 3.5 - It should be installed at the place that have no danger of explosion, it also has no gas and conductive dust which would cause metal-corrosion and insulation-damage. 3.6 - Maximum install inclined Angle 5° , it should be installed at the place has no obvious impact and weather-influence. 3.7 - Main circuit installation type: III, Auxiliary circuit and control circuit installation type:ll 3.8 - External magneticfield of Installation location should not exceed than 5 times of earth magnetic field. 3.9 - Installation electromagnetic environment: B type
