Could anybody explain 1 For what does IAC stand for? IAC is a General Electric electromechanical overcurrent relay. Characteristic curves of electromechanical overcurrent relays are the result of electrommagnetic and spring torques, and do not follow ANSI or IEC equations. The characteristic curves of electromechanical relays are developed by testing. There are also some sample points worked out for the various relay types. This manual is available over the internet at www. Regards, Raisinbran. This is the code selected by the manufacturer for the electromechanical family of time inverse. Relays manufacturer are not required to comply with standards in this matter. Hi all, Thanks a lot for all your answers. It is a very valuable forum to be in touch always.
