Overview

The Mersen U09372 End Barrier is a precision-engineered accessory designed for 600A/30A Class J SJ type adder fuseholders, ensuring safe and reliable electrical connections in industrial applications. This end barrier converts a 30A SJ adder pole to a single pole, enhancing system integrity by preventing accidental contact with live components and mitigating arc flash risks. Engineered for durability, it withstands mechanical stress, thermal cycling, and environmental contaminants, ensuring consistent performance in power distribution systems, motor control centers, switchgear, and industrial control panels where Class J fuses are standard. The U09372 is UL and IEC certified, meeting stringent industry standards for electrical safety and compliance. Installation is tool-free, requiring no specialized procedures—the barrier snaps securely into place, providing a clean, insulated finish. Ideal for space-constrained applications, it eliminates the need for additional insulation components while maintaining full compliance with safety regulations. Compatible with Mersen’s 30A and 60A Class J fuse blocks, the U09372 supports copper wire connections only, with recommended mounting screws of 1/4" (0.250" dia). Trusted by professionals in electrical engineering and maintenance, this component delivers reliability and operational safety in critical electrical applications.
