3 Summary

Earthing switches of series EK6 are determined for indoor installation and conform to the requirements of GB1985 and IEC 62271-102. They are fitted with snap-action operating mechanisms for positive high-speed closing and sufficiently dimensioned to conduct the rated short-circuit making current when closed under load. The speed of the snap-action closing operation is independent controls. The earthing switches are supplied as kits with a pre-assembled active part and correspon ding earthing con tacts supplied loose. Correct in stallation of these parts in a switchgear panel results in a functioning earthing switch. Routine tests toGB1985 and IEC 62271-102 are to be carried out at site accordingly.
