Function of remote monitor terminals
When the PIII DS is operating correctly, the terminations 1-2 are connected
to normally closed contacts, 2-3 are normally open. If the internal varistor
component is damaged as a result of thermal overloading, terminations 1-2 will
then be open and 2-3 closed.

SURGE ARRESTERS - VARISTOR
PIIIM is surge arrester type 2 according to EN 61643-11. Complete device consists of a base
part and pluggable module. These arresters are recommended for use in the Lightning Pro-
tection Zones Concept at the boundaries of LPZ 1-2 (according to IEC 1312-1 and EN 62305)
for equipotential bonding and elimination of transient overvoltage that originate during
atmospheric discharges or switching processes. The combination of PIIIM + B20M is suitable
for use in TNS and TT systems.
The main use of PIIIM arrester is in all kinds of industry, residential and administration buildings.
They are to be placed into the secondary switchboards or into the control box.
