Hoc est circuitus interruptor vacui (VCB) a 40.5 kV, qui ad systemata commutatoria insulata gas (GIS) composita, integrantes functiones triplices (disrumpendi, isolandi, et terrae ducendi) ad simplicem controllem potestatis altae tensionis. Id supportat currentem nominalem de 1250 A et capacitem disrumpendi de 31.5 kA, securitatem contra circuitos breves et overcurrents in retibus mediae ad altissimae tensionis praebens.
Adoptans designum modulare, id structura compacta, bono performantia disrumpendi, alta securitate, longa vita servitii, isolatione perfecta, sine necessitate maintenance, parvo spatio occupato, et usui lato in rete annulari industriale et civili, et in rete alimentationis terminali. Praecipue aptum ad stationes distributionis secundariae minores, stationes commutationis, enterprises industriales et minerarias, aerodromos, vias ferreas, vias publicas, metropolitas, areas commerciales, areas habitatorias, ventos electricos, optoelectronicam et alia campos.

Annua SF6 pressionis et humiditatis inspicienda est; mechanismus trium positionum quinquennis inspectio debet; interruptor vacuum non habet regularem manutentionem. Supportat monitorationem remotam pressionis et partialis disiunctionis ad praedictivam manutentionem perficiendam
Idoneum est pro apparatu commutationis GIS 35kV1250A in stationibus transformationis, distributione electricitatis industriali, alimentatione trahendi ferroviaria, et oneribus criticis sicut centra data, quae requirunt altam fiduciam et operationem frequentem
Integrat tres functiones in unum: claudendo (portando/interrompente currentem), isolando (isolatione tuta pro maintenance), et terram ducendo (terram ducendo pro securitate instrumentorum), cum interlocking mechanicum ad praeveniendum maloperationem, quod est integratum et fidelem magis quam commutationes separatae
