Features:
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 96°C~240°C and they can be used for all kinds of products with rated current of 0.5A~15A.
• Electric blower
• Electric furnace
• Microwave oven
• Refrigerator
• Coffee machine
• Sandwich furnace
• Electric motor
Structure & Operating Theory:
RYD fusible thermal cutoff is to put heat sensitive grain material (organic chemicals) into metal cover for over-heat shut off. The main feature is that it can cut 10A or 15A high current (rated current).

Maximum of TM planted temperature:thefuse will not change its state,until reaches rated temperature
Holding temperature of TH:it keeps working normally within this scope( the temperature should not be too close to therated temperature during the installation of fuse,otherwise,misoperation may occur).
Rated action temperature of TF: the tolerance of cut-off temperature are+0-5°C.
Note:if need for safety regulations report,pleaseselectmodelswith”O”.
