Fenarro Zn Series Vs1 Indoor High-Voltage Vcb Vacuum Circuit Breaker

1. PRODUCT OVERVIEWThe FRZN-VS1 indoor high-voltage vacuum circuit breaker is an indoor switching device for a 24KV power system with a rated voltage of 50Hz. It serves as a protection and control unit for power equipment in the electrical grid and industrial and mining enterprises. It is suitable for frequent operations under rated working current or places with multiple short-circuit currents. This circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body. It can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.Series chart:Indoor High Voltage Side-Mounted Vacuum Circuit BreakerIndoor High Voltage Sealed Vacuum Circuit BreakerIndoor Electrified Railway Vacuum Circuit BreakerHandcart Series (Isolation Cart, Fuse Cart, PT Cart, Measurement Cart)2. USAGE CONDITIONS♦ Ambient air temperature: -15ºC to +40ºC; ♦ Altitude: ≤3000m (if higher altitude is required, the rated insulation level should be correspondingly increased); ♦ Amplitude: Seismic intensity not exceeding 8 degrees; ♦ Average daily relative humidity of air not exceeding 95%, monthly average not less than 90%; ♦ No fire, severe pollution, explosive, chemical corrosion, or severe vibration3.
