The 281-611/281-418 is a 2-conductor fuse terminal block designed for overcurrent protection in DIN-rail mounted applications. It utilizes WAGO's CAGE CLAMP® technology for secure, front-entry wiring of copper or aluminum conductors from 0.08 to 4 mm² (28–12 AWG). The block features a pivoting holder for a 5 x 20 mm miniature metric fuse and includes a 120V neon lamp that provides clear visual indication of a blown fuse. With an electrical rating of 800V and 10A, this terminal block is ideal for industrial control panels and automation systems requiring reliable circuit protection and rapid fault diagnosis.
