Table 12 - VCB15 Technical Parameters
Type VCB15_LD8 VCB15_MD1 VCB15_HD1
“Close” and “Trip” Dry Contacts Inputs of the CM
Output voltage ≥ 30 V
Contacts closed current ≥ 50 mA
Steady state current ≥ 5 mA
1) The rating depends on the metal-enclosed switchgear ventilation. Temperature rise type test at 2500 A in Cradle was successfully passed in KEMA.
2) The information in brackets refers to the national Chinese standards GB1984-2003 at an installation altitude of 1000 m maximum.
3) At 34% DC component.
4) At 40% DC component.
5) Smaller timing on request.
6) The number of sequential Close-Trip operations with a 10 second interval 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.
7) Isolation resistance check is not applicable for “Actuator Coil” circuits of CM.
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.
9) Overall dimensions of VCB are provided in “Appendix 3. Overall Drawings”.
10) At 5 min short-term duty. Continuous current – 5 A.
11) In case of dry contacts “close” and “trip” are open.
12) At Cos j >0.66.
13) At Cos j >0.33.
