Safety instructions
• Mounting and installation may only be done
by trained technical personnel, according to
the recognized technical rules, regulations,
and relevant standards!
• Insufficiently tightened locking screws lead
to an inadmissible rise in temperature!
• Always observe the permitted ambient
conditions (see technical data and catalog).
• Devices with visible transport damage
must not be used.

The TA200DU thermal overload relay is authorized
under device group II, category (2) in the "G" area
(areas with potentially explosive gas, steam,
smoke or air mixtures).
PTB 02 ATEX 3045
II (2) G
The TA200DU thermal overload relay is not suit-
able for installation and/or operation in poten-
tially explosive areas. When using the devices in
potentially explosive areas, preventive measures
must be taken, e. g. within suitable enclosure.
For starter combinations with TA200DU devices
and AF motor contactors appropriate protection
against short-circuit is to be selected for reaching
coordination type "2" according to EN 60947-4-1.
Information regarding verified starter combina-
tions is provided online by ABB.
