ZE/XTOM overload relays

In addition to the degree of protection specified in the
standards EN 60079-14 and VDE 0165 Part 1, further
provisions have been made to ensure safety from ignition for
motors operated in potentially explosive atmospheres.
EN 60079-7 prescribes additional measures to be taken for
the operation motors with "increased safety" type of
protection "e". These measures improve the degree of
safety and prevent impermissible high temperature and
development of sparking and arcing, which is usually not
found when motors are operated under normal conditions.
The motor-protective devices for this that are themselves not
located in the Ex e area must be certified by an accredited
certification body.
For for motors in explosive dust–air mixtures, standard
EN 60079-14 specifies additional measures.
Directive 94/9/EC (ATEX 100a) on the approximation of the
laws of the Member States concerning devices and protec-
tive systems intended for use in potentially explosive areas
has been in force since 06.30.2003.
The ZE/XTOM motor protection system is approved by the
PTB in accordance with the Directive 94/9/EC (ATEX 100a).
The EC Type Examination Certificate Number is:
PTB 10 ATEX 3014
