SEFUSETM is a compact and reliable thermal cutoff designed to protect domestic electrical appliances and industrial electrical equipment from fire. Cutoff occurs and an electrical circuit opens when ambient temperature increases to an abnormal level.
Two SEFUSE types are available. The SF type uses an organic thermosensitive material as the thermal pellet and its operating temperature range is 73¡æ to 240¡æ.
The SM type uses a fusible alloy and has an operating range of 76¡æ to 187¡æ.
SEFUSE is manufactured in Japan and Thailand, and both factories are certified by the International Standards Organization (ISO) for the ISO9001 quality standard.
