Range of SCHOTT SEFUSE® D6 battery fuses and SEREB® thermal battery protection switches

Lithium Ion Battery Fuses and Switches

Whether powering a smartphone or an electric bike, protecting Li-ion battery packs from overcurrent and overcharging is key to safety and reliability. SEFUSE® battery fuses and SEREB® thermal battery protection switches are used to protect Li-ion battery packs. SEFUSE® battery fuses include D6S type and S type, which protect Li-ion batteries from overcurrent and overcharging. The S type is a lead-free* product that reduces environmental impact. SEREB® battery protectors prevent overheating and overcurrent.

A wealth of experience in reliable electronics protection

SCHOTT has a strong reputation as a specialist in electronics protection. Leveraging our expertise with SEFUSE® thermal links, which prevent electronics from catching fire due to overheating, we apply the same high-quality standards and extensive experience to develop and manufacture SEFUSE® battery fuses and SEREB® thermal battery protectors.

SEFUSE® D6S battery and SEREB®

Product variants

SCHOTT offers two types of protection devices for rechargeable Li-ion batteries: the SEFUSE® battery fuse and the SEREB® battery protector. SEFUSE® battery fuses include D6S and S types, which protect Li-ion batteries from damage and abnormalities caused by overcurrent and overcharging. SEREB® thermal battery protection switches are resettable devices that detect abnormal temperature rises of battery cells to prevent dangerous overheating.
