Ferraz Shawmut - Mersen TR4/10R 250V 4/10A 2x9/10 RK

Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers. Features: Time-delay; Current-limiting; AC & DC rated; Optional solid state SmartSpot blown fuse indicator; Time-delay for motor start-ups and transformer inrush currents without nuisance opening; Current-limiting for low peak let-thru current; Rejection-style design prevents replacement errors (when used with recommended fuse blocks); Easy-to-read label for quick brand recognition and replacement; Metal-embossed date and catalog number for traceability and lasting identification; Fiberglass body provides dimensional stability in harsh industrial settings; High-grade silica filler ensures fast arc quenching and high current limitation - Applications: Motor circuits; Mains; Feeders; Branch circuits; Transformers; Service entrance equipment; General-purpose equipment - Approvals & Standards: UL listed to standard 248-12 File E2137; CSA certified to standard C22.2 no. 248.12; DC listed to UL standard 248 TRS only
