Feed-through terminal
An insulating part consisting one or
more terminal groups that are isolated
from each other, and designed be
mounted carrier.5 0.2 mm2

circuits 1000 AC/1000 or
up 1500 DC.
• Terminals that directly contact
the conductor through cutting
or which create contact points
by penetrating the insulation, for
example insulation eg.12 1282250000 2012/2013

be solid, multi-strand fine-strand

as insulation displacement
