Voltage control relay 12 - 60 kV

high-voltage

For transfer, safety grounding, or tap selection at 12kV to 60kV peak test in air. Most HV contacts have full insulation above ground. A higher insulation level to ground is optional. Most units are spring return, can mount in any position, or may also be used with gravity return by mounting in the proper position. E series units are also available with replaceable tungsten alloy contacts for high current capacitor discharge applications. High momentary and continuous current ratings are a natural result of large radiuses used to minimize corona. For holding or indicating one, two or more SPST, 11A, 250V AC auxiliary contacts are available on the E12, E15, E25, and E40; the E30 and E60 normally use 15A 250V AC and 1/2A, 125V DC auxiliary contacts. Other auxiliary contact ratings are available. Available up to 300kV PK.
