Functional and reliable e²ALPHA switchgear belongs to the group of modern, four-compartment indoor MV switchgears suitable for wall- or self-standing installation. The standard range of e²ALPHA consists of cells with a width of 400, 600, 750 and 800 mm. The high degree of operational safety for e²ALPHA switchgear was achieved by applying an extended system of mechanical and electrical interlocks as well as reinforced mechanical cell construction characterized by a high level of arc resistance.
e²ALPHA switchgear is an ideal solution for industrial-, distribution- and mining power companies. Advanced design combined with reliable interlocks makese²ALPHA ideal for applications in the strategic areas of power system where the highest reliability of power supply is required (eg. MPS-Main Point of Supply, power plants and mines).
ADVANTAGES OF THE e²ALPHA SWITCHGEAR
- easy adaptation to customer requirements
- high level of arc resistance
- upper opening tray for circular circuits enables easy access to wiring (control circuits)
