Table 13 - VCB25 Technical Parameters
Type
VCB25_Shell2
Switching time
5 ms
“Close” and “Trip” Dry Contacts Inputs of the CM
Output voltage
≥ 30 V
Contacts closed current
≥ 50 mA
Steady state current
≥ 5 mA
1. At 34 % DC component.
2. Smaller timing on request.
3. 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.
4. Isolation resistance check is not applicable for “Actuator Coil” circuits of CM.
5. 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.
6. Overall dimensions of VCB are provided in “Appendix 3. Overall Drawings”.
7. At 5 min short-term duty. Continuous current – 5 A.
8. In case of dry contacts “close” and “trip” are open.
9. At Cos j >0.66.
10. At Cos j >0.33.
