Hi
I am trying to use a reed switch ( rated 3amp 500v DC) to operate an AC timer relay. Presumably this is a small coil with minimal DC resistance but significant inductive resistance to AC ( probably the wrong terminology but best I can do!!) My query is when the circuit first opens is there a surge of current before the induced resistance kicks in and would it be sufficient to fuse the switch? The timer will operate the starter of a .75kw 3ph fan.
