This 46 kV switch is commonly used for capacitor bank switching in substations.  It is solenoid operated because it is used in three phase sets requiring simultaneous contact closure.  This switch can precisely close at zero voltage to reduce capacitor bank in-rush currents.  The solenoid operating current is 60 to 65 amperes peak for 1-1/2 cycles per switch mechanism.

An inadequate supply of control current can cause of improper operation.  It is best operated with a stored energy control as shown here.  These switches have one form A (e.g. normal open) and one form B (e.g. normal closed) auxiliary contact.  Repair parts are shown beginning here.
