The Thermal Cutoff Product Division develops and produces thermal protection devices, widely known as NEC SCHOTT SEFUSE^®, that meet a number of international industrial safety standards. These devices are designed to protect electrical equipment from catching fire by sensing overheating and cutting off the electrical circuit immediately.

NEC SCHOTT SEFUSE^® is a highly reliable thermal protection device that provides long-standing excellent performance and is used in various appliances and components.

A wide choice is provided in order to suit the application and meet various requirements of operational temperatures between 73°C to 240°C as well as of rated currents from 0.5A to 15A. Cadmium- and lead-free versions are also available.

NEC SCHOTT manufactures three types of thermal cutoffs, namely:

The SF type uses an organic thermo-sensitive material inside a metal case and is able to operate in electric circuits with large currents. [more]

The SM type contains a fusible alloy inside an insulated case which interrupts the electrical circuit by melting when ambient temperatures reaches abnormal levels. [more]

NEC SCHOTT SEFUSE^® D6 series is a thermal cutoff device containing an electrical resistor. [more]
