Fusible heat cutoff is small and strong heat protector that can detect if the temperature is abnormal and cut the circuit. It can be used to detect abnormal temperature rising of electrical appliances for home and industrial use and circuit can be cut rapidly so as to prevent fire disaster. 

Fusible heat cutoff has two types.One is RYD model which use heat sensitive grain materials(organic chemical) as heat sensitive material and the other is RHD model which has low melting alloy. Rated operating temperature is 96C ~240C and they can be used for all kinds of products with rated current of 0.5A ~15A.
