Using scope: 
Applied to Air Conditioning Related，Digital AV Household Appliance，Copier，Lighting Fixture，Amusement Device,On-board Device, and so on.

Operation principle: 
When thermal cutoff sense a abnormal heat cause by abnormal operation of component /equipment through thermal cutoff body and leads wire, the fusible alloy melt by reaching at the temperature of the melting point of the ally. 
An electrical circuit of the thermal cutoff is opened with forming two separate ball at the edges of the leads by surface tension of the melted fusible alloy. 
Special resin accelerate the surface tension of the melted fusible alloy.
