Overview

The Mersen 61008SJ Class J fuse block is a high-performance, UL4248-listed component designed for 600VAC/DC applications up to 100A. Engineered for compatibility with Class J fuses (AJT, A4J, HSJ), this 3-pole fuse block features robust tin-plated copper clips with spring reinforcement for secure contact and enhanced conductivity. The unit accommodates stranded or solid copper or aluminum conductors ranging from 2/0 to #6 AWG, with a torque rating of 100 in-lb for reliable connections. Insulated with glass-filled polycarbonate (GFPC) for dielectric strength exceeding 2500V, the 61008SJ is ideal for industrial control panels, motor protection, and distribution systems requiring compact, multi-pole fuse blocks. Its unique adder block configuration enables field assembly of 1-, 2-, or 3-pole segmented blocks, reducing inventory needs. Certified to UL Guide IZLT (File E52283) and CSA Class 6225 (File 32169), this Mersen product ensures compliance with stringent safety standards. The side-clip design simplifies installation in tight spaces, while the high SCCR rating of 200kA provides superior fault protection.
