Thermal-magnetic residual current circuit breaker RDX16LE-63

ground faultearth-leakageresidual current

RDX16LE series residual current operated circuit breaker, is mainly applied to the circuit of AC50Hz, rated working voltage 230V or 400V, rated current up to 63A for protecting human indiretly against electric leakage, and for preventing the fire result from the ground fault due to the damaged insulation of the equipment or circuit. Normal working condition and Installation environment 3.1 Temperature: no higher than +40 ºC , and no lower than -5 ºC, lower temperature, for instance, when temperature at +20ºC, is +40 ºC. The product can withstand the higher humidity under changes should be taken care in special measurements and the average temperture no higher than +35 ºC. 3.2 Altitudeof Installation location no more than 2000m. 3.3 The relative humidity: no more than 50%, when Temperature the product can withstand 90% relative humidity. The condensation that happened because of temperature 3.4 Class of pollution : 2 Class 3.5 Electronicmagnetic environment: B 3.6 The megnetic field of the installation place should not bigger than the earth magnetic field in any direction. 3.7 Installation method: TH35-7.5, distribution box or cabinet. 3.8 Installation: The angle between the vertical plane and installation plane no more than 5. 3.9 Installation condition: the installation location should have no heavy impact and vibration, and in the medium that no danger (explosion). 3.10 Installation type : 2 ,3 Class Struction and Working principle This series residual current operated circuit breaker is consisted by Main switch, zero-sequence current transefomer,leakage tripping, testing devices in a plastic case.
