Product Description
EK6-12/40.5kV Indoor AC High Voltage Earthing Switch with 31.5kA Short Circuit Current and Snap-Action Mechanism
Product Introduction
The EK6 series earthing switches are designed for indoor installation, complying with GB1985 and IEC 62271-102 standards. These switches feature snap-action operating mechanisms for reliable high-speed closing and are robustly constructed to handle rated short-circuit making currents when closed under load.
The closing speed is independent of operator controls. Supplied as kits with pre-assembled active parts and corresponding earthing contacts, these switches require proper installation in switchgear panels for full functionality. Routine tests according to GB1985 and IEC 62271-102 standards must be performed on-site.
Normal Operating Conditions
- Ambient temperature: Operating range: -25℃ to +40℃ (Storage/transportation permitted down to -30℃)
- Altitude limit: Below 1000m
- Relative humidity: Below 90%
- Seismic rating: Not exceeding intensity class VIII
- Environmental requirements: Installation area must be free from fire hazards, explosion risks, excessive dust, chemical corrosion, and severe vibration
