Mersen A4J Fast Acting/Class J Fuse, 600VAC/300VDC, 200kA AC/100kA DC, 125 Ampere, 1-5/8" Diameter x 5-3/4" Length, for Excellent Current-Limiting Protection

Mersen fast acting class J fuse deliver excellent current-limiting protection to a wide variety of applications. Their unique dimensions prevent the substitution of other fuse with lower voltage ratings, interrupting ratings, or current-limiting capability. Features and benefits: High current limitation for low peak let-thru current. Unique dimensions prevent replacement by other fuse classes. Fiberglass body provides dimensional stability in harsh industrial environments. Easy-to-read imprint label for quick recognition and replacement. Applications: capacitors, load centers, panelboards, switchboards, bus duct, feeder circuits, circuit breakers, lighting, heating and general loads. Approvals: UL listed to standard 248-8 File E2137, CSA certified to standard C22.2 no. 248.8, DC listed to UL 248, IEC 269-2-1. Volts ratings: 600VAC/300VDC. I.R ratings: 200kA AC/100kA DC. Current-limiting capability as 125 ampere. Measures 1-5/8-inches diameter by 5-3/4-inches length.
