Product Description
STN2 / STN3 Series( Similar with Schneide Compact NS, NSX type) molded case circuit breaker(Electronic MCCB) is one of new type breakers which our company adopts international advanced design, manufacture technology to develop. The rated insulating voltage is 950V. Suitable for AC 50Hz (60Hz). Rated working voltage 690V or below, rated working current is 12.5A to 630A of circuit and used in distributing electric energy. Non-frequent making and breaking in the normal conditions and protecting when circuit and installation are overload, short circuit and lacking voltage. Rated shell-rack and the breaker whose current is under 400A, take protection effect when mouse cage motor's non-frequent start, breaking off working and protecting form overload, short circuit and lacking voltage. The product conforms to GB14048.2, IEC 60947-2 standards.
Ambient air temperature
The ambient air temperature is about +40 ºC; the ambient air temperature is below -5ºC; the average value of ambient air temperature 24h is not more than +35ºC.
Elevation: installation elevation of not more than 2000m.
Atmospheric condition:
Relative humidity of the atmosphere in the surrounding air temperature of +40ºC is less than 50%; the relative humidity at the lower temperature can be high; most of the wet month average maximum relative humidity of 90%, the monthly average minimum temperature of +25ºC and considering the temperature due to changes in product surface.
Pollution grade: grade 3.
