A high-temperature shutdown protecting relay comprises a base; a L copper pin and a N copper pin are provided on the base with resting contacts provided at their bottoms respectively; stretchy copper blades are provided on the base, which are fit to the L copper pin and the N copper pin respectively, with movable contacts provided thereon, which are fit to said resting contacts; a stand is provided on the base and above the stretchy copper blades; grooves are provided on the lower side of the stand with ceramic rods for insulating the stand from the stretchy copper blades embedded therein. The high-temperature shutdown protecting relay provided by the present utility model can keep normal operating property under high temperature. When the movable contacts and the resting contacts are engaged with each other, a larger locking force can be kept therebetween; when the movable contacts and the resting contacts are disengaged, there is a larger disengaging force to ensure these two kinds of contacts disengaged, and to ensure a certain disengaging interval therebetween and very quick disengaging time.
