1) For VCB ISM15_Shell with Low upper terminal – up to 1250 A, with High upper terminal – up to 2000 A.
2) The information in brackets refers to the national Chinese standards GB1984-2003 and installation altitude of maximum 1000 m.
3) Parameter valid only when ISM is used with insulation masks. For details see dimensional drawings and accessory information.
4) At 40% d.c. component.
5) The number of sequential Close-Trip operations with interval 10 seconds should not exceed 10. The number of Close-Trip operations should not
exceed 60 per hour. Sequence of 10s Close-Trip operations can be repeated only after 260 s pause.
6) At Cos j >0.66.
7) At Cos j >0.33.
8) Up to an installation altitude of 1000 m above sea level. Above 1000m, the external insulation measurement of the ISM must be increased by
the atmospheric correction factor Ka according to IEC 62271-1 compared to the insulation measurement at sea level. The maximum allowed
altitude is 2000 m above sea level.
