DC contactor [RE-wrenches]

[Kirk Herander, VT Solar]

Kurt,

Square D makes a circuit breaker which can be turned on and off by a 24 vdc
signal. You could perhaps "load shed" the Trace using the auxillary relays
via battery voltage. I don't have the part #s at hand, but will find and
post them if you're interested. I'm pretty sure they're made in a 60 amp
flavor.
