I have a 24VDC Coil with 26.8ohm resistance and Inductance of 1.69. It's a contactor coil but can't find the inrush current rating. Can someone tell me how to calculate it with the above info?
Hi,
Being an inductor, it opposes the initial current flow and the final current will be 24V÷26.8Ω. The current rises from zero to this final value with a time constant of R/L secs. So there will not be an in rush current for an inductance.
