AuCom EMX4i soft starter: top of the range, up to 1000 A and 630 kW
The EMX4i is AuCom's flagship series. Current from 24 to 1000 A. Power up to 630 kW at 400 V, 27 catalogue positions. The widest AuCom line we hold. Standard supply is 200-525 V. There are also high-voltage versions reaching 1200 V, which we bring in to order and which are worth asking about early.
We pick the EMX4i when the job does not fit the lower series. Simple, no alternatives. Adaptive start control lets you shape the acceleration profile for a specific machine rather than just setting a time. Extended diagnostics and communication let the unit report into a control room. Typical sites are crushers, mills, piston compressors and large pumping stations, where breakaway torque runs several times above rated and an ordinary starter simply trips. If you need less current and no communication, look at the EMX4e or the base CSX.
What we ask before quoting
Nameplate motor current plus load type. For hard breakaway we go one frame above the calculated size, because a crusher starts nothing like a centrifugal pump of the same rating. Then starts per hour and cabinet temperature: above 40 °C derating applies. The bypass is built into the whole series, so no external one is needed.
