Anyone know what this is? A relay of some sort?
Thanks

Might that go on a ksu?

Hi
It is a polar relay used in very sensitive circutes.
Most common used is in Central office and PBX trunks.
Has very little use in today's world unless you collect C.O. equipment.
Your best place to find a new home for it is in the TCI Switchers section.
