Precharge resistor... ? Answered

Maybe I missed this above, but, what's the point of a contactor if you're going to put a non-switched resistor around it? I would think you'd at bare minimum want an on off switch that would add or remove the precharge from the circuit. Otherwise, your controller will always be hot, and depending on the resistor wattage, if you try to operate with the resistor only in the circuit, that resistor isn't long for this world...

My medium voltage drives have a contactor for the main and precharge contactors for exactly this reason.
