Application

In the field of distribution and sub-transmission automatic, reliable control and status
indication of primary switching components both locally and remotely is of
significant importance. They are needed especially in modern remotely controlled
substations.
P3SSXSWI is designed to be used for status indication of a three-state (earthing
switch closed, disconnector closed and both open) switch.
