Abstract
A device provided with fire protection includes a casing (102), electrical components (103) inside the casing, and a fan element (104). The casing includes a first wall having ventilation apertures and the fan element is configured to produce ventilation flow through the ventilation apertures so as to cool the electrical components. The device further includes a fire protection element (105) including thermally expanding material (109) configured to suppress the ventilation flow via the ventilation apertures in response to a situation in which the thermally expanding material is exposed to heat and gets expanded. The fire protection element is outside the casing, the 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 fan element. Therefore, the fire protection element can be a post-installable element.
