H-3 circuit Breakers and SD relay
H-3 circuit Breakers and SD relay
(OP)
Hello everybody,
We are currently working in a project where some old fashion circuit breakers are still in use, they are H-3 from Federal Pacific and they are equipped with its "control unit" kind SD-3 or SD-6.
We used to have a manual of these control units, however, it has disappeared, my question is:
Is there anybody who has SD Control unit manual and willing to share it?
Best Regards
