Product Introduction
VS1-Series embedded pole. vacuum circuit breakers are applicable to 12kV, three-phase AC 50Hz indoor switchgear and can serve as protection and control units for industrial and mining establishment transformer substation equipment. With a modular and independent-frame design for their spring operating mechanisms, VS1-Series circuit breakers can operate with KYN28 mid-set and fixed switchgear. These circuit breakers are subject to both fixed installation and assembly with a truck as a handcart unit.
Normal service condition
| Altitude | ≤1000m | |
| Ambient temperature | Max | +40℃ |
| Min | -15℃ | |
| Ambient humidity: Maximum average humidity | 24 hours ≤95% | |
| 1 month ≤90% | ||
| Maximum water vapor pressure | 24 hours ≤2.2kpa | |
