SEGA-M SIMOPRIME A4 24kV AIS Switchgear — Metal-Clad Withdrawable up to 25 kA

The SEGA-M SIMOPRIME A4 is a type-tested metal-clad, withdrawable air-insulated switchgear (AIS) rated up to 24 kV, manufactured under the Siemens SIMOPRIME Technology Partner agreement. Featuring a withdrawable vacuum circuit-breaker truck type 3AH, compact 800 mm single-panel width, and fully mechanically interlocked compartments, it delivers 25 kA short-time withstand and 2,500A normal busbar current. All switching operations are performed behind the closed HV door. No SF6 gas, no heat-shrink insulation — long-term reliability without ageing risk. Compliant with IEC 62271-200 with internal arc classification. Manufactured at SEGA-M’s 30,000m² facility in Egypt.

    Key Features

    🛡️

    All Operations Behind Closed HV Door

    Operational safety guaranteed for every switching task — no personnel exposure to live medium-voltage components.
    🔋

    Vacuum Technology — No SF6 Gas

    Maintenance-free switching device reduces lifecycle cost and eliminates SF6 environmental compliance risk.
     
    📐

    Compact 800 mm Panel Width

    Reduced switchroom civil cost; 800A CB panel is only 500 mm wide — minimising footprint further.
     
    🔧

    No Heat-Shrink Insulation

    Insulation integrity does not degrade over time — no risk of breakdown from ageing or thermal cycling.
     
    🔄

    Individual Truck for Each Switching Device

    Easy exchange of circuit-breakers without de-energising adjacent bays, maximising system availability.

    IEC 62271-200 Type Tested with Arc Classification

    Provides documented arc-flash containment evidence required for insurance and critical facility approvals.
