Old Relay.circa 1970's
Can anyone tell the time a Reyrolle 3B3 relay takes to trip.
The relay is set up as a REF. Instantaneous.
Set for 15V (0.5A) sec current from CT (1200/5)
30ohm resis in parallel with relay.
ie what is defined as "instantaneous" in this case, or is there a curve somewhere.
regards,
mrbj
