I know from large 48V 1000A switch gear used in a telco environment, that you get a meaty arc when it opens, with magnets used to push the arc against ceramic "arc breakers" to cause it to extinguish cleanly. If the concern is that you want clear control of the current through the load, then a MOSFET is definitely the way to go. | |
