34kV 600A Single Pole Harmonic Filter Switch
|1 POLE RH||200-200||34||600||SOLENOID||120VAC||1003377||1003355G1|

These switches are for switching harmonic filters up to and including the 12th. harmonic. They can be connected in parallel for current capacities of up to 1000 amperes. The right hand and left hand configurations are used to minimize the differences in inductive reactance in the current paths though two switches connected in parallel.
Unlike the Joslyn™ switch of a similar design, the modules on the Vacuum Electric Switch Co.’s harmonic filter switch contain grading capacitors to assure even distribution of the recovery voltage over the three modules. Modules with and without grading capacitors cannot be combined on the same switch and are special for this switch.
The switch is solenoid operated and comes with the buss bars on either the left or right hand sides. This switch contains one form A (e.g. normal open) and one form B (e.g. normal closed) auxiliary contact. A control for operating this switch is shown here. The repair parts except for the modules are the same as for the 34kV switch shown here.
