JN2-40.5 type indoor high-voltage grounding switchDetailed product description：

The JN2-40.5 indoor high-voltage grounding switch is an indoor high-voltage electrical appliance designed based on the grounding switch section of GB1985-89 "AC High Voltage Isolation Switches and Grounding Switches", which is equivalent to IEC 129-84 "Isolation Switches and Grounding Switches" and IEC 694-84 "Common Provisions for High Voltage Switchgear and Control Equipment". JN2-40.5 type grounding switch is suitable for power systems with three-phase AC 50Hz of 35KV and below, and has a voltage monitoring device. Its structure is simple and reliable, with low operating force and easy installation and debugging. It is usually used in JYN1-40.5 and GFC-40.5 switchgear, and can also be used separately.
