DESCRIPTION:
In the circuit of AC 50Hz,its rated working voltage is under 400V and 690V,its rated working current reaches to 1600A,could be used for controlling the low voltage distribution net and keeping it safety.It is used to distribute electric energy,protect line and power equipment from overload,short circuit,undervoltage,single-phase grounding fault.Circuit unnecessary power outage,improve the safety and reliability of power grid operation.Under normal conditions,it can be used for infrequent switching of routes.
Classify: 1. Accord to install:Fix type,Drawer type. 2. Accord to pole:3P,4P 3. Accord to operation:Electric operation,Manual operation(Repair,maintenance) Normal use and installation condition 1. Ambient air temperature:upper limit value not exceeding+40ºC,lower limiting value not exceeding -5ºC,average value not exceeding +35ºC.Special orders expected. 2. Install address of altitude not exceeding 2000m. 3. Atmospheric conditions:Atmosphere relative humidity not exceeding 50% when ambient air is +40ºC,it can have higher of relative humidity in the lower temperature ,the average max relative humidity is 90% in the max wet month,this month average max temperature is +25ºC at the same time ,it need to think about condensation of product's surface which will with the change of temperature.It need consult with my company when it exceed regulated requirements. 4. Level of protection:IP30,IP40(Install protective door frame) 5. Class of pollution:3 class. 6. Use classes:B classes 7. Transportation and storage conditions:-25 ºC ~+70 ºC
