WebInrush Current Limiters (ICL) Inrush Current Limiters (ICL) are designed to limit an initial large flow of electric charge that occurs when a device is first turned on. The Current steady state max range is from 100 mA to 80 A with the Resistance at Current ranging from 1 mOhms to 30.3 Ohms and a lead spacing range of 0.098” to 1.378”. WebDec 20, 2011 · The high inrush current results when the variac is arbitrarily turned on at or near the peak input waveform voltage. Turning it on at the zero-crossing should reduce the inrush close to it's normal operating current. A zero-crossing solid state relay will do, provided that it is also zero-state turn off as well.
