Surge protection with individual components
• With suppressor diodes
Suppressor diodes work similarly as conventional
Zener diodes. The diode becomes conductive within
10– 100ps after a certain breakdown voltage,
set by the manufacturer, is exceeded. Compared to
Zener diodes, suppressor diodes have a higher current-
carrying capacity and a shorter reaction time.

Tender specification sheets
Long specification Feed-through terminal,
12.4mm wide with varistor
arrester between the
signal line connection
and the mounting rail
potential, TS 35 contact
base.A signal with max.
32A can be protected
here. When the terminal
is fitted, a simultaneous
electrically conducting
contact is made between
the mounting rail (earth)
and the reference potential
(ground) of the protection
circuit in the terminal.
Optical identification of the
terminal based on the type
of protected switching
and the voltage level. The
terminal can be labelled or
marked.
