Further information
For more detailed information please refer to the national and/or international
standards, directives and regulations!
Type “n” ignition protection additionally requires electrical components to be
marked with the following extended identification:
The following classifications according to NEC 500 (National Electric Code)
are valid for North America.
The "Divisions" describe the degree of probability of whatever type of
dangerous situation occurring. Here the following assignments apply:
Electrical components for explosion endangered areas are subdivided in three
danger categories:
A – non spark generating (function modules without relay /without switches)
AC – spark generating, contacts protected by seals (function modules with
L – limited energy (function modules with switch)
Explosion endangered areas due to combustible gases, fumes, mist and dust:
Division 1
Division 2
Class I (gases and fumes):
Class II (dust):
Class III (fibers):
relays / without switches)
Encompasses areas in which explosive atmospheres are to be expected
occasionally (> 10 h ≤ 1000 h /year) as well as continuously and long-term
(> 1000 h /year).
Encompasses areas in which explosive atmospheres can be expected rarely
and short-term (>0 h ≤ 10 h /year).
Group A (Acetylene)
Group B (Hydrogen)
Group C (Ethylene)
Group D (Methane)
Group E (Metal dust)
Group F (Coal dust)
Group G (Flour, starch and cereal dust)
