The Mersen A6D4.5R is a high-performance, 4.5-amp current-limiting fuse designed for the protection of motor circuits, transformers, and general industrial equipment against short circuits and overloads. This Class RK1 fuse is rated for a maximum voltage of 600V AC and 300V DC, with a high interrupting rating of 200,000 RMS symmetrical amperes AC, ensuring robust fault clearing capability. Constructed with a melamine tube and silver-plated contacts, the A6D4.5R features a compact 13/32-inch by 1-1/2-inch cartridge body for easy installation in standard fuse blocks. It complies with UL 248-12 and CSA C22.2 No. 248.12 standards, providing reliable branch circuit protection in motor control centers, panelboards, and disconnect switches. This fuse is ideal for applications requiring time-delay characteristics to accommodate inrush currents while offering superior current limitation for downstream component protection.
