AuCom CSX soft starter: a 7.5-110 kW basic unit, nothing extra
The CSX is the simplest device in the AuCom range. Three switches on the front: ramp time, stop time, initial voltage. Set them, close the cover, forget about it. Nobody usually opens it again for the life of the installation, provided the load has not changed and the machine was not rebuilt. We stock 11 positions, 18 to 200 A, 7.5-110 kW at 400 V. Supply is 200-440 V, so Ukrainian 380 V is covered without caveats.
We pick the CSX when the start is ordinary and motor protection already sits separately in the panel. Pump. Fan. Unloaded conveyor, grinding machine. If protection has to live inside the unit, look at the CSXi, which brings electronic protection and a bypass. The price gap at the same 110 A is UAH 47,900 against UAH 65,780. For hard starts or SCADA communication the CSX is out entirely, that calls for the EMX4i.
What we ask before quoting
Rated current from the motor nameplate, not the machine documentation. We see a 5-15% discrepancy regularly, and it is exactly why a unit sometimes gets swapped after installation. Then load type and starts per hour: the base CSX has no bypass, so the thyristors need time to cool. A bypass comes with the C2 version, and that should be settled at quotation stage, because the configuration cannot be changed after delivery.
Prices and documentation
The CSX-007-V4-C1(C2) at 18 A costs UAH 14,180, and the top CSX-110-V4-C1(C2) at 200 A is UAH 47,900. We send the series manual and brochure with the invoice, before payment, in English. The full AuCom line sits in the AuCom soft starters section, and everything else in the soft starter catalogue.
