SEFUSE Brand Thermal Fuse

client5The SEFUSE brand SF-E and SF-R series thermal fuses are designed for high current applications. The thermal sensitive pellet in the SEFFUSE brand TCO liquefies when the temperature rises to the melting point of the thermal element. This, in turn, allows a spring action to permanently break the electrical circuit.
