The Littelfuse RUEF110-2 is a thermally activated resettable fuse with a polymeric (PPTC) Positive Temperature Coefficient (PTC) design for over-current protection in automotive, commercial, and consumer electronics applications. This resettable fuse can be used to protect against short circuits, overloads, and over-temperature conditions. It is a self-resetting, single-use fuse that will automatically reset after an over-current or over-temperature condition has been corrected. The RUEF110-2 has a maximum current rating of 100A (Imax) at 30V, and a trip current rating of 1.1A. Additionally, this fuse has a current-limiting time of 3 seconds, and a maximum voltage of 30V. The RUEF110-2 is RoHS compliant, and meets UL, CSA, and VDE standards for safety.
