Bussmann FWH5-12-5A6FR - Current-Limiting Fuse 12.5A (50kA@500V Interrupting Rating)

Bussmann FWH5-12-5A6FR is a low-voltage current-limiting fuse designed for protecting sensitive electrical equipment and conductors from short-circuit faults. It features a 500V AC voltage rating with a 12.5A current rating and provides very fast-acting (VFA) interruption to clear high-level faults. The fuse construction utilizes a single-barrel design with ferrule connections, measuring 0.25 inches in diameter and weighing 5.19 lb, built to withstand industrial environments. This fuse meets industry standards for current-limiting performance with an interrupting rating of 50kA at 500V AC. Typical applications include protection of motor controllers, transformers, and power distribution components where rapid fault clearing is critical.
