Industrial Bussmann JCY-400X 5500V fuse is a high‑voltage, medium‑voltage protection device in the JCY family, designed for circuits up to 5,500 volts. It carries a 400 A current rating and is specified for operation at 60 Hz, making it suitable for protection in MV switchgear, transformers, and distribution panels. The JCY line is engineered to interrupt fault currents in industrial power systems, helping prevent equipment damage while integrating with standard Bussmann fuse clips used in industrial assemblies.
