MERSEN TR500RID Fuse time-delay class-RK5 indicator 200kA 500A 250V

Tri-Onic® TR fuse current-limiting fuse time-delay characteristic safely handles harmless starting currents and inrush currents associated with todays motors and transformers. 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 catalogue 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. Clip mounting. Ferrule blade connection terminal type. Polyester body material. Copper and tin-plated copper material contact. Applications: motor circuits, mains, feeders, branch circuits, transformers, service entrance equipment, general-purpose equipment.
