I don't know if it was made specifically for it, but its shown on page
2-3 of my KWS-1 manual on the RF connections diagram used externally
from the KWS-1 to connect a 75A-4 and a KWS-1. The external contacts are
used to prevent transmitter keying before the relay closes. The BNC
connection goes to the receiver. The relay power circuit comes through a
selenium diode from 120 volts so is about 110 volts DC.

I believe it to be fairly generic, and I may have one here too.

So its good for at least 750 watts RF and used for HF in this situation.
