GE Electromechanical Relay
GE Electromechanical Relay
(OP)
Hi,
I am sure you have seen it and done it all. I am not used to electromechanical relays and had my first encounter with them recently. I have a GE PJC32 relay
http://ww w.gedigita lenergy.co m/app/View Files.aspx ?prod=pjc& amp;type=3
It is a instantenous relay with a curve charc. Customer has a 250E fuse which does not seem to be coordinating with this 4800A Inst. OC setting. Could you kindly suggest me any other option interms of electromechanical relay may be Extremely or Very inverse which could replace my Inst O/C relay and still serve the same purpose by providing coordination betweek fuse and O/C relay.
Thanks

RE: GE Electromechanical Relay
One question would be, do you have other time overcurrent protection installed, and if so do you really need the PJC.
As alehman says you could substitute another relay such as a 77 or slower. If your PJC is in an S1 case, then any GE IAC relay designed for the S1 case (as most of their old overcurrent relays are) will slide in. You may need to do some minor wiring on the case to get the time overcurrent output hooked up though.
