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.

JN15 -24/31.5 Series indoor earthing switch is a new design and improved on the JN15 type (the installation size does not change). It is suitable for electric power system with 20~24KV, 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.
