Technical Details of SEFUSE®
SEFUSE® thermal links product table
There are two SEFUSE® types: SF and SM. The SF-type uses thermosensitive material as the thermal pellet, while the SM-type uses a fusible alloy. Both types are suitable for a wide range of applications.
SEFUSE® thermal links SF type - Ratings
* BEAB Certification Non-Renewal
BEAB certification, which had been obtained for some series of SEFUSE® thermal links, will not be renewed after the expiration date of February 2022.
* About CCC Self-Declaration number
Due to the publication of new implementation rules from the Certification and Accreditation Administration of the People’s Republic of China (CNCA), the authentication method of thermal links was changed to CCC Self-Declaration (Index No. 2019-1571296947171 / Document No. 2019 No. 44). SCHOTT SEFUSE® thermal links that had acquired CCC certification have completed the conversion to the CCC Self-Declaration accordingly.
* CCC Certification : Update GB/T9816.1-2023 Standard
The applicable standard of CCC certification for SEFUSE® thermal fuses has been updated to GB/T9816.1-2023.The self-declaration number remains unchanged.
