I'm looking for information on a GEC Earth fault relay.
It's quite old and controls a shunt coil on a LV breaker.
GEC Measurement.
CDG 11AP  2001 JD5
No. 068124M.

It is used in conjunction with over-current relays
CDG 34ER2003Jd5
No. 068122M

A circuit diagram or connection information would be very helpful.

I have one at home I think - will post later unless someone beats me to it. smile

If we learn from our mistakes I'm getting a great education!

I have a few CDG manuals - I've dumped them on a filehost:

If I remember correctly the CDG 34 is a 3-pole version of the CDG 14, so there should some information in the other files for that one.

If we learn from our mistakes I'm getting a great education!
