TF 240 Celsius Degree Cutoff Thermal Fuse AC 250V 10A

The TF Thermal Fuse RY-240° C 10A 250V is a one-time thermal cutoff device designed to protect electrical appliances from overheating. When the surrounding temperature reaches the rated cut-off point of 240°C, the internal fusible element melts and permanently breaks the circuit to prevent potential fire hazards. This thermal fuse is widely used in heaters, hairdryers, transformers, power supplies, and other high-temperature environments.

Key Features of TF Thermal Fuse RY-240° C 10A 250V:

• High Cut-Off Temperature: Operates at a fixed cut-off temperature of 240°C for overheat protection.
