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.2 cable and conductor systems,
including accessories, may only installed moved under ambient
temperatures which are within the limit values specified the

Protection against high temperatures
Installed electrical appliances generate power loss during operation.
The enclosures manufactured Spelsberg are tested dur-
ing the approval test for maximum power loss the enclosure.
