Overview

The Mersen J220072 is a Class J fuse designed for superior current-limiting protection in industrial power systems. Rated for 600VAC and 300VDC, this fast-acting fuse delivers exceptional interrupting ratings up to 200kA AC and 100kA DC, ensuring reliable operation even in high-fault scenarios. Its unique dimensions prevent substitution with lower-rated fuses, enhancing safety and compliance in critical applications. The fiberglass body provides dimensional stability in harsh environments, resisting corrosion and mechanical stress. With UL 248-8 and CSA C22.2 No. 248.8 certifications, the J220072 meets stringent safety standards for panelboards, switchboards, bus ducts, and feeder circuits. Ideal for capacitor banks, lighting, heating, and general loads, this fuse combines fast response with very high current limitation to protect sensitive equipment from damaging fault currents. Available in amp ratings from 1A to 600A, the J220072 is a versatile solution for modern industrial power distribution systems where uptime and reliability are non-negotiable.
