Title:

PROTECTIVE DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/133538

Kind Code:

A1

Abstract:

The present invention provides a protective device which has a large rated voltage and a large rated current, which is capable of sufficiently suppressing arc generation during operation, and which is further capable of providing suitable protection against overcurrent caused by short circuiting or the like of a main circuit. This protective device includes: (i) a protective element which includes a first temperature fuse and a resistor, and in which the resistor generates heat as a result of current passing therethrough when a defect has occurred, and the first temperature fuse is activated by this heat and interrupts the current; (ii) a PTC element and a second temperature fuse which are electrically connected in parallel to the first temperature fuse, and which are electrically connected in series to each other; and (iii) a current fuse which is electrically connected in series to the first temperature fuse.
