Ross Engineering High voltage Relay E Series

 Transmission, safety grounding or tap selection for 12kV to 60kV peak testing in the air. Most high pressure contacts have complete edges on the ground. Higher ground edge level is optional. Most units are spring returned and can be mounted anywhere, or can also be used by mounting in place with gravity reset. The E Series unit also offers replaceable tungsten alloy contacts for high-current capacitor discharge applications. High instantaneous and continuous current ratings are a natural consequence of the large radius used to minimize corona. E12, E15, E25 and E40 provide auxiliary contacts for holding or indicating one, two or more SPST, 11A, 250V AC; The E30 and E60 usually use 15A 250V AC and 1/2A and 125V DC auxiliary contacts. Other auxiliary contact ratings are available. Available up to 300kV PK.
