High voltage reed switches
Wroclaw Division of PIT-RADWAR S.A. is a producer of reed switch used to switch small and medium power (miniature reed switches), to switch high power (power reed switches), to switch high voltage (vacum reed switches) and changeover reed switch.
High voltage reed switches

High voltage reed switches type ZP are assigned to switch and separation high voltage circuits from 5kV (ZP-1) to 19kV (ZP-6).
HV reed relays type K56xH, K55xH and R-56x are based on our HV reed switches.

Basic parameters are below. Additional information are attainable in section Documentation » Data sheets.
Parameters of high voltage reed switches type ZP are tested in standard coil CP-12 ».
