Overview
Through-type terminals with isolating blade capability are the
most commonly used terminal types in instrumentation and con-
trol. Key features of the hybrid isolating blade terminals are their
narrow width of only 5.2 mm and their high current carrying ca-
pacity of 16 A. Ø 2.3-mm test plugs can be fitted on both sides
of the isolating point. A special feature of this terminal type is its
three bridge slots: the two slots that all the combination plug-in
series have in common and an extra one on the other side of the
isolating point.
The isolating blade is secured to the terminal so that it cannot be
lost.
