Definitions

  • the fuse of the electric air heating device extends outside the housing and is mounted serially in the electric circuit.
  • said at least one tube made of non-fuse metallic material and said at least one tubular insulator extend coaxially to the tightening shaft.
  • the fuse 10 is a tube-shaped fuse. However, nothing prevents the fuse 10 to be differently shaped.
  • the fuse 10 can be made of various materials.
  • the material of the fuse 10 is so chosen to adjust the melting temperature so that the thermal cut-off is adaptable to different electric air heating devices 1.
  • the fuse 10 is made in an alloy material with a fusion temperature adapted to the use conditions of the electric air heating device 1.
  • the electrical insulation ring 14 and the tubular insulator 12 are so chosen and disposed to prevent any direct electrically conductive contact between the shaft 9,23 of the screw 22 and the housing 2.
  • the electrical insulation ring 14 and the tubular insulator 12 are chosen and disposed so that the electric current flowing through the heating ribbons 3, flows necessarily through the fuse 10 to reach the grounded housing 2.
