Overview
With the two voltage levels routed through two separate tiers, the
combination two-tier plug-in terminals require 50 % less space
than equivalent single-tier terminals. To implement a wide range
of switching tasks, connecting combs can be fitted to both tiers
of the combination two-tier plug-in terminals.
