Model
Structure feature
This disconnect switch consists of pedestal, insulating brace, electric material and operating mechanism. There are two braces
on each pole, and electric blade is installed on the top of each brace and the connection point of the two blades is between the
two braces. With the driving of operating mechanism, the two blades can rotate horizontally ninety degrees to close. We can
connect three single-pole disconnect switches into a linkage three-pole switch through interlink rod. This disconnect switch can
be matched with CS11 type or CS17 type manual mechanism, thereinto, CS17 be used in disconnect switch with earthing fitting.
(motor mechanism can be installed according to user’s requirement), Reasonable structure, fle xible operating; conv enien t
installation, able to use single-pole or three-pole; wide distance of contact, safe and reliable insulating. The earthing type is
flexible according to user’s requirement, single earthing dual earthing or without earthing can be chosen.
