motor-protective circuit-breakers
Foreword
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 50019 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.
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 PKZM4/XTPR…DC1 motor protection system is
approved by the PTB according the 94/9/EC (ATEX 100a)
Directives.
