High-voltage vacuum circuit breaker VBPK-35-25/1600 U3.1

Vacuum switch VBPK-35-25/1600 U 3.1 is designed for operation in electrical networks of three-phase alternating current with a frequency of 50 Hz with a rated voltage of 35 kV with an isolated or grounded neutral, as well as for the protection of electrical circuits in emergency modes with disconnection and inclusion of short-circuit currents.

Use of the switch in modes and conditions other than those specified in this manual and technical conditions KUUZH.674153.001 TU must be agreed with the manufacturer.

Operating Conditions:

The switch is manufactured in climatic version U, placement category 3.1 according to GOST 15150-69 and retains its parameters within the limits of norms and requirements established by TU, during and after exposure to the following external factors:

- altitude above sea level up to 1000 m;
- atmospheric pressure from 86.6 to 106.7 kPa;
- sinusoidal vibration in the frequency range from 0.5 to 100 Hz with an acceleration of 10 m/s2 (1 g);
- upper value of air temperature at eq
