SEFUSE SEREB Thermal Cut-out
SEFUSE® SEREB are a range of miniature battery protection devices for use with Li-ion cells and other battery technologies.
SEREB miniature thermal circuit-breakers are self-latching (i.e. non self-resetting) responding to both over-current and over-temperature cell conditions. The SEREB SB protector operates via a small bimetal thermal element that heats up, opens circuit and is then kept open by a miniature PTC heating element. The SB battery cut-out will only reset once the battery fault is removed.
Only 1 mm thick and with 5 calibrations ranging from 72°C to 90°C, the SEREB SB series can be fine-tuned to offer critical thermal protection for rechargeable and primary battery applications.
