VS1-24E Vacuum Circuit Breaker

Basic Info

Model No.: VCB 24/1250-25E

Product Description

Vacuum Circuit Breaker

Product Type: Indoor AC HV VCB

General Description:

VS1-24E series of vacuum Circuit Breaker is three-phase A.C. 50Hz indoor high-voltage distribution device with 24KV rated voltage and below which can match with GZS1 type cubical Switchgear. It is suitable to control and protect transmission and distribution system such as power generation plant and substation, especially used in the fields where it is frequently operated.The operating Mechanism of this series of circuit breaker is that of spring energy-stored type which can be operated by A.C. or D.C., also by manual control.

Applying ambient conditions:

1. The elevation should be no higher than 1000m.

2. Ambient temperature: The max. temperature should be +40C. The min. temperature should be -10C.

3. Relative Humidity: The average humidity of a day should be no more than 95%. The average humidity of a month should be no more than 90%.

4. Saturated Vapour pressure:The average saturated vapour prereure of a day should be no more than 2.210-3 Mpa; The average saturated vapour prereure of a day should be no more than 1.810-3 MMpa.

5. It should be used in the places without fire, explosion, serious filth, chemical erosion and violent vibration.
