Model No.: (EK6) JN15A-12\/31.5<\/strong><\/p>\n

EK6\u201112\/31.5 Series indoor earthing switch is an upgraded design developed on the basis of the ES1 type. It is applicable to 3\u201312 kV three\u2011phase AC 50(60) Hz power systems. Serving as earthing protection equipment, it can be installed in various medium\u2011voltage switchgear assemblies. The product complies with GB 1985\u20112004 and IEC 129 standards. Our high voltage earthing switches are essential safety components designed for medium voltage metal clad switchgear. Engineered for rapid closing and superior short circuit making capacity, these switches ensure the safety of maintenance personnel.<\/p>\n
