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.

A fire protection device for small electrical devices provided with a housing, comprising 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, which
- a) breaks the vessel wall at a predetermined trigger temperature due to thermal expansion thereby causing the bursting capsule to rupture;
- and
- b) has a fire preventing effect and/or an extinguishing effect
A small electrical appliance with a housing, in which electrical components are disposed, wherein a fire protection device is disposed in the housing and the fire protection device comprises a bursting capsule featuring a hollow space that is completely enclosed and delimited by a vessel wall, and wherein a liquid is disposed in the hollow space, which
- a) breaks the vessel wall at a predetermined trigger temperature due to thermal expansion thereby causing the bursting capsule to rupture;
- and
- b) has a fire preventing effect and/or an extinguishing effect.
A use of 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, which
- a) breaks the vessel wall at a predetermined trigger temperature due to thermal expansion, thereby causing the bursting capsule to rupture, and
- b) has a fire preventing effect and/or an extinguishing effect, as a fire protection device for a small electrical device by disposing that bursting capsule in a housing of the small electrical device.
