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 KEY FEATURES & BENEFITS Tri-Onic TRS-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 TRS-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers. 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 Product Specifications Item Number TRS300R Description Fuse TRS-R - Class RK5 - Time-Delay 600VAC 600VDC 300A Blade Tri-Onic® EAN/UPC Code 782001749231 Rated voltage AC UL 600 V Rated voltage DC UL 600 V Frequency 50/60 Hz Ampere Rating 300 A ROHS Compliant Yes AC or DC AC/DC Fuse Class Class RK5 Speed/Characteristic Time Delay Mounting Clip AC Max I.R./Breaking Capacity: I1 200 kA Connection/Terminal Material Tin-Plated Copper Connection/Terminal Type Blade Body/Insulating Material PolyTube
