A current limiting element for preventing electrical overcurrent including a principal current conducting member made of a low resistance conductive elastomer having a high coefficient of thermal expansion and having a flattened cross-sectional shape and a heating/heat insulating member which consists of a high resistance conductive elastomer or a resistive coating surrounding the circumference of the conducting member.

Current limiting element for preventing electrical overcurrent

A current limiting element for preventing electrical overcurrent manufactured by mixing conductive particles with an elastic insulating material which possesses a positive coefficient of thermal expansion, such that particles are normally in electrical contact with each other, and the elastic material interposed between the particles is caused by heating to expand so that the electric circuit is interrupted.
