14049.A SCHEMATIC DIAGRAMS 5.5 MVS Schematic Diagrams The MVS medium voltage soft starter is rated for 80 A to 321 A at 2.3 kV to 7.2 kV. AuCom can supply the soft starter in an IP54 or IP42 style panel with two switchgear configurations. These are referred to as E3 and E2 panel options. E3 panel option The standard E3 panel option consists of a combined main isolator/earth switch, a main and bypass contactor and a set of MV fast-acting line fuses (R-rated). Refer to the MVS section for details of optional panel equipment. The panel can be supplied in a stand-alone format or with rear, horizontal busbars for an MCC switchgear line-up.

14050.A SCHEMATIC DIAGRAMS E2 panel option The standard E2 panel option consists of a main and bypass contactor. A means of isolation and earthing, as well as some form of line protection, must be supplied and installed separately, upstream of the E2 panel. Refer to the MVS section for details of optional panel equipment.
