The ABB EK6/ST‑E MT585 assembly is a motor‑operated medium‑voltage earthing switch system designed for integration into indoor electrical switchgear panels. It combines the EK6 earthing switch mechanism with an ST‑E electric drive actuator and the MT585 motor module to allow remote or automatic closing and opening of the earthing switch. This system is used to safely connect high‑voltage circuits to earth for maintenance, testing, or system protection, and is suitable for high‑current earthing duties with reliable mechanical and electrical performance.
