Abstract

A fire protection device for small electrical devices provided with a housing. The fire protection device includes a bursting capsule featuring a hollow space that is completely enclosed and delimited by a vessel wall, wherein a liquid is disposed in the hollow space. The liquid breaks the vessel wall at a predetermined trigger temperature due to thermal expansion thereby causing the bursting capsule to rupture. When the vessel wall ruptures and releases the liquid it has a fire preventing effect and/or a fire extinguishing effect.
