Hi guys
I have the gigavac gv242mab contractors and resistors.
What do the red, black, white and blue wires do?
Does anyone have a precharge and HV circuit we can follow?
Thanks

Both wires leed to coils. One pair is for hard turnon and the other pair is for holding.

Isn't one pair the low voltage auxiliary contacts?
"This is a new old stock Gigavac GV242MAB side mount contactor with normally open auxiliary contacts. It has a rating of 400+ A and max. rated voltage of 800VDC."
