Device with fire protection

Equipment comprising:

• at least one component device, and
• a body device comprising mechanical structures for receiving the component device so that the component device is in its operating position when supported by the mechanical structures,
• the at least one component device comprising the following parts:
• a casing comprising a first wall having one or more ventilation apertures,
• at least one electrical component inside the casing,
• at least one fan element configured to produce ventilation flow through the one or more ventilation apertures so as to cool the at least one electrical component, and
• a fire protection element comprising thermally expanding material configured to suppress the ventilation flow via the one or more ventilation apertures in response to a situation in which the thermally expanding material is exposed to heat and gets expanded,
• wherein the at least one fan element is mechanically supported to the casing and the fire protection element is removable and re-installable without detaching the mechanical support between the casing and the at least one fan element, and wherein the mechanical structures of the body-device are suitable for supporting the component device in its operating position also when the component device is without the fire protection element.
