Tested down to the details
Quality you can depend on ...
Weidmüller enclosures are often exposed to harsh
conditions during use. Because of their excellent quality,
they provide years of reliable protection against water,
dust, strong impacts, vibration, corrosion and extreme
temperature uctuations.
All components used in areas requiring explosion protection
are subject to strict security requirements. All of their
functional details must be tested to make sure they are
durable and tough enough to perform under extreme
environmental conditions.
Since an enclosure is only as reliable as its weakest
component, Weidmüller makes sure that each component
complies with the same high quality standards – so there are
no weak spots on the entire enclosure.

TB enclosures have been certied and
approved according to the new IEC/EN 60079 set of
standards. This set of standards denes a harmonised
approach to designing and manufacturing equipment for
areas requiring explosion protection.
The enclosures must comply with the requirements found in
the empty enclosures standard according to EN 62208 and
IEC 60079-0, 7 and 31. These specify the following tests:
Empty enclosure standard, acc. to DIN EN 62208
