The TF130C2A is a precision metal-type thermal fuse designed to provide essential over-temperature protection for low-to-medium power electronic devices and small appliances. Rated for a conventional current of 3A and a maximum voltage of 250V, this safety component acts as a non-resettable, "one-shot" electrical link. It is specifically calibrated to permanently open the circuit when the ambient temperature reaches its precision-engineered threshold of 130°C, effectively isolating power to prevent equipment damage or fire hazards caused by localized overheating.

This metal-cased variant features a robust, conductive alloy body that facilitates rapid heat transfer to the internal thermal element. This design ensures a swift and accurate response to temperature spikes, making it ideal for monitoring components that are sensitive to moderate heat increases, such as small transformers, electric fans, power adapters, and solenoid valves. Its compact, leaded structure allows for seamless integration into tight wiring harnesses or direct mounting onto PCB components via soldering or crimping, providing a reliable fail-safe for delicate electronics.

Because the TF130C2A is a safety-critical component, it must be installed in close thermal contact with the heat source it is intended to monitor. Once the fuse has been activated by a thermal event, the internal element melts and cannot be reset, requiring a full replacement of the unit to restore electrical continuity. Its 130°C rating makes it a standard protection requirement for ensuring the longevity and safety of everyday consumer electronics and specialized industrial control circuits.
