i have no idea what you are talking of.
what has the current to do with the protection?
the protection is for corrosion prevention.
or do you mean the etch resist (which protects the copper in the etchant)?
for that much current you nead thick coated clad and make broad traces.
what do you want to make?
if i would have to mke a 200A circuit i would try much to leave the high
current circuit off the pcb.
(wire it with suitable wires and only connect the control/sensing cables to
a control pcb)
it may be possible to reduce track with by soldering copper wire on top.
a possibility is sqare copper rods, but the soldering techniqe has to be
put care on.
in most high current circuits the components are not so well suited for pcb
mount and it may be even easier to wire it without a pcb.
so please be more specific what the problem is.
