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.

JN22B- 40.5/31.5 series indoor HV earthing switch is researched and developed by HV Electric research organization, with advanced design and steady performance, simple structures, simple mounting end adjustment, suitable for electric power system with 40.5KV, Three- phase, AC 50Hz.As an earthing protection, it can be used in KYN- 40.5 or other kinds of switchgears. It is complied with GB 1985- -2004 and IEC129 standard.
