SEFUSE SF-R Thermal Fuses

Our new smaller SF-R series thermal fuse replaced the larger SF-E series, but still has the same contact capacity and wide temperature range.  The smaller fuse body size means a faster thermal response to dangerous overheat situations.

The SF-R fuse is a one-time device and has to be replaced if it has blown.  There are 17 settings available from 70deg.C to 240deg.C to cover a wide range of applications from small personal care products to large kitchen appliances.

All settings listed below are readily available from stock for next day delivery.
