High voltage reed relays are assigned to switch and separation high voltage circuits from 5kV to 19kV.
There are produced 2 type of relays:
 
 - type K-55xB - leads of reed switches are performed by elastic HV cables, leads of coil are adapted to PCB mounting,
 
 - type K-56xB - all leads of relay are adapted to PCB mounting.
