MV Switchgears are classified in 4 main groups as follows according to the IEC 62271-200 standard.

1-Subdivision Class

  • PM Partition: Switchgear providing continuous metallic partitions and/or shutters, intended to be earthed, between opened accessible compartments and live parts of the main circuits.
  • PI Partition : Switchgear having one or more non- metallic partitions or shutters between opened accessible compartments and live parts of the main circuit.

2-Internal Arc Classification (IAC)

  • SME series LSC-2A type metal enclosed switchgears internal arc classification is AFL,
  • SNC and SMC series LSC-2B type metal clad switchgears internal arc classification is AFLR.

A: Only authorized personnel can access

F: Accessible from the front

L: Accessible from the lateral

R: Accessible from rear

3-Loss of Service Continuity (LSC)

  • LSC 2A : defines the switchgears that opening and interfering of switching compartment is allowed while only busbar compartment is energized.
  • LSC 2B : defines the switchgears that opening and interfering of switching compartment is allowed while both cable and busbar compartment is energized.

4-Isolation of Cells

  • Air Insulated
  • Gas Insulated

Aktif Elektroteknik manufactures SME series Air Insulated LSC 2A (Metal Enclosed) and SNC / SMC series LSC 2B (Metal Clad) type switchgears.
