Protection against high temperatures
Installed electrical appliances generate power loss during operation.
IQ products are resistant mineral oil, vegetable fats and
animal fats.

Protection against chemical influences
For installations areas with increased levels hazardous substanc-
es the environment, the suitability may correspondingly reduced.2 cable and conductor systems,
including accessories, may only installed moved under ambient
temperatures which are within the limit values specified the
manufacturer the relevant product standard.
Switchgear assemblies are designed for ambient temperatures of
between -25 and +35 (24-hour average).
Detailed tables this topic are provided the catalogue, taking
into account the ambient temperature and type installation. temporary increase
in temperature not problem.
Even if, for example, products from Spelsberg are suitable for
temperatures between -40 and +80 °C, the manufactur-
er‘s instructions and the requirements the relevant product safety
standards, such line current, fault circuit breakers fuses,
should checked when designing the enclosure.
The enclosures manufactured Spelsberg are tested dur-
ing the approval test for maximum power loss the enclosure.
