CA 2170048

Use of PTC circuit protection devices in automobile wiring systems. The devices can replace some or all the fuses convention- ally used. Preferred devices contain PTC conductive polymers. This enables the current-carrying capacity of at least some of the compo- nents of the harness to be reduced; for example the gauge of some of the insulated wires can be reduced from 18 AWG to 22 AWG.

Utilisation de dispositifs de protection de circuit à coefficient de température positif (PTC) dans des systèmes de câblage pour voitures. Ces dispositifs sont aptes à remplacer une partie ou la totalité des fusibles traditionnellement utilisés. Les dispositifs de préférence utilisés contiennent des polymères conducteurs PTC. Ceci permet de réduire la capacité de charge d'au moins certains des éléments du faisceau; le calibre de certains des câbles isolés peut notamment être réduit de 18 AWG (calibre des fils) à 22 AWG.
