Helping to reduce weight of wire harnesses, PPTC devices distributed in a circuit can allow the use of smaller wire sizes with the resulting harnesses. Forego looping back and forth around a fuse box and place your protection wherever you see fit. The solid state composition of PPTC devices helps provide reliability.
