Product Description

The grounding switch is a type of electrical switch that is used to connect or disconnect an electrical circuit from the ground. It is typically used to provide a safe path for electrical current to flow to the ground in the event of a fault or short circuit.

JN17-12/40 (Old type is JN15-12/40) Series indoor high voltage earthing switch is a new design and improved product based on the ES1 type. The structure is assembled and suitable for electric power system with 3~10KV, three- phase and AC 50(60)Hz. As an earthing protection, it can be used in various kinds of HV switchgears. It meets GB1985-2004 and IEC129 standard.
