Smico Series Load Isolation Switch 63a-3150a

SGL series load isolation switch

   SGL series load isolation switch is widely used in the distribution system and automatic system of architectur,electrical power,petrochemical,and other industries.

   The kind of load isolation switch possesses flexible structure of modularized design,possesses flexible and veraatile compositionality,it adopts the shell made by unsaturated

polyester resin reinforyced by glassfibre.It has very high dielectric performance,protctive capability,and reliable operation.

   The operationg mechanise is an elastic-accumulating accelerating mechanism for instant relase,which makes instant on and off the double breakpoint contact.It has no

relationship with the speed of iperating handle and increases greatly various eletric properties and mechanich properties.

   Many forms of sturctres and operationg in which the on and off state of contact is observed through windows.There are operations inside and outside the board.There are frontal

and lateral operations.There are connections behind the board.

  This kind of switch has a good-looking outline and various functions,being very novel,simple and small dimensioned,and the best choic among the congeneric products.
