Product Description

Indoor 24kv 230mm 630A Gas Insulated Load Break Switch for RMU Ring Main Unit

FLN36-24D/T630-20 indoor AC high voltage SF6 load switch and FLRN36-24D/T1250-31.5 indoor AC high voltage SF6 load switch fuse combination apparatus is suitable for protecting the line of 24kV Electric Power Load Control System. It is designed for three-phase 50Hz ring network or terminal power supply and industrial electrical equipment.

The load switch can handle load current, closed loop current, no-load transformer, and cable charging current. The combined apparatus can break any current reaching the rated short circuit, making it ideal for ring network units, box type substations, and more.

This product is especially suitable for urban residential areas, small substations, opening and closing stations, industrial and mining enterprises, large shopping malls, airports, subways, hospitals, stadiums, etc.

Ambient Conditions:

• Altitude: ≤2000m


• Ambient Temperature: -40°C to +40°C


• Earthquake Intensity: ≤8 degree


• Relative Humidity: Daily averages ≤95%, Monthly average ≤90%
