Mersen 20308R Class R Fuse Block – 3-Pole, 30A, 250V AC/DC, Box Lug Terminal, Spring Reinforced

The 20308R is built with a glass-filled polycarbonate (GFPC) base, providing exceptional dielectric strength and thermal stability. It features spring-reinforced clips made of high-conductivity tin-plated copper, which maintain high-pressure contact even under heavy thermal cycling. This block is part of a modular system where "adder blocks" can be snapped on to create custom multi-pole configurations.
