МС-К магнитного пускателя с кнопкой

MS-K Magnetic starter with button 1. APPLICATION The starter is with the application of 50/60Hz AC voltage to 660V, current to 95A, The following circuit as the control of three-phase squirrel cage ,to Start, stop and reverse starting the moter. Which is with the small volume, installation convenience features. It has lost pressure and overload protection performance. The starter applied to the environment under normal use (with out explosion-proof, anti-corrosion). The products have many kind of with buttons, button-sealed Circle and without button, etc.It is apply to hot and humid area. Technical data: a model by loading products, specifications, capacity control. 2.The normal working and installment conditions 1. Surrounding air temperatures: The surrounding air temperature upper limit does not surpass +40 °C, the lower limit is not lower than -5°C, The average temperature does not surpass +35 °C in 24 hours. 2.Installation sites altitude above sea level does not surpass 2000m. 3.Atmospheric relative temperatures does not surpass 50% when the surrounding air temperature are 40 °C, Can not have a higher relative humidity in a lower temperature, In the wettest month monthly average most low temperature is +25 °C, the monthly average maximum relative humidity is 90%, and consideration the dew on product surface.Because of the temperature change 4.Installation sites environmental pollution can be 3 levels. 5.Install category is III kind. 6.Install condition: A. Installment gradient with vertical not to surpass 5°b. Installs in without remarkable vibration and impact place. 3.Main technical parameter 1,Rated frequency 50Hz 2,Rated insulation voltage 660V 3,Rated working voltage 220V, 380V, 660V 4,Rated fixed working voltage and the rated current of thermal relay and the maximum power of controlled three phase AC motor
