Rated current: 40A-5000A Export for 10 years OEM offered It is suitable for power supply system with rated insulating voltage is AC800V, ratedworking voltage is AC690V, and below DC250V, and AC 50Hz/60Hz, rated working current is 20A-5000A of two-path 1.Ambient medium temperature: less than +40°C and more than -5 °C2 h average value less than+35°C2.Altitude: not over 2000m;3.The max ambient air relative humidity when the maximum temperature is +40C does not surpass 50%,in compares under the low temperature to be possible to allow the high relative humidity, the wettest monthly average min temperature is +25C,this monthly mean maximum relative humidity is 90%, the dew on the surface of the product must be taken into consideration because of the temperature change.4.Class of pollution: 35.The breaker should be put in the place where there isn't any explosive medium and conductive dust and no gas, which would corrode metal or destroy the insulation. Reliable and safe interlock: It has reliable connection and disconnection main circuit and second circuit function, and the setting has self-locking function. It has safety insulation isolate. Quick transfer speed,(the transfer time is 0.1s-0.2s), low malfunction, easy maintenance, and reliable capability. Small in volume, simple in constitution, large current and ATSE integrate. With the controller, the setting can transfer between the manual and automatic, and has the every protection function. Make sure the facility safe, it has neutral pole N input first and breaker later function, which can avoid of the abnormal voltage. It adopts DC instantaneous excite way. Electric degree: PC class.
