Product Overview

JN15-24 series Indoor AC HV Earthing Switch(hereinafter referred to as eathing switch) is applied to indoor grounding device with rated voltage 24kV, three-pole alternating current 50Hz. Its performance meets the requirements of the national standards GB 1985-2004 High-voltage Alternating current Disconnector and Grounding switch. It can be used in armoured and movable type AC metal enclosed switchgear. According to requirements of Safety Work Order, when the electric equipment power outage, the earthing switch should be closed to make grounding short circuit artificially to guarentee the maintainers can get safe and reliable ground potential protection. At the same time, with live display device,it can prevent turning off the earthing switch. Once the error occurred, it can avoid Other equipment from being damaged with making capacity.
