Abstract:
A circuit protective device with a positive temperature coefficient element is provided, which includes: a positive temperature coefficient (hereinafter "PTC") element, made of a conductive composition having a PTC characteristics, provided for shutting off an electric circuit; a circuit board having the PTC element and electrodes to be connected with the PTC element; and a slot formed on the circuit board so as to prevent a low resistance conductive passage from being formed between the electrodes, the low resistance conductive passage being made of powder of the conductive composition released from the PTC element. And also an electric junction box with the above circuit protective device is provided. Thus, the circuit protective device or the electric junction box with the circuit protective device wherein a low resistance conductive passage made of a carbonaceous powder to be released from the PTC element is not formed between the electrodes of the PTC element can be realized.
