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<br />
starter in an IP54 or IP42 style panel with two switchgear configurations. These are referred to as E3 and E2 panel<br />
options.<br />
E3 panel option<br />
The standard E3 panel option consists of a combined main isolator/earth switch, a main and bypass contactor and a<br />
set of MV fast-acting line fuses (R-rated). Refer to the MVS section for details of optional panel equipment.<br />
The panel can be supplied in a stand-alone format or with rear, horizontal busbars for an MCC switchgear line-up.<br />
