  • Air insulation for long term reliability.
  • Low voltage test mode aids commissioning.
  • Real time clock for event monitoring
  • Comprehensive event and trip logging
  • Customizable Protection Each protection setting can be individually set to: (Trip , Warn & Log , Log Only)
  • Comprehensive protection settings to ensure safe operation of the motor and the load.
  • Advanced Thermal Modelling
  • Informative Feedback Screens
  • HMI Customizations (The MVE HMI screen can be customised to suit user requirements, with shortcut keys and a status screen displaying user-selected information)
  • Dual Parameter Set



Current range : 50 ~ 500A nominal
Motor connection : In-line
Rated voltage class : 2.3kV to 13.8 kV

  • Optimize performance for any motor and load combination.
  • Soft stop reduces or eliminates water hammer in pump applications.
  • Simplicity. The soft starter provides a complete motor control solution in one package. This includes advanced motor protection, input/output signals for remote control/monitoring and a wide range of communication options.
Oil and Gas

MVE soft starters are perfect for the control of liquid and gas pumping. As well as the standard MVE soft starters, AuCom also has a range of arc proof panel systems for your consideration.

Water and wastewater

Water hammer is solved using the MVS soft starter, as well as stopping pumps without causing damage to pipework, check valves and other equipment. AuCom soft starters are able to offer a variety of protections as well as starting and stopping functions.


The MVS is the ideal starting solution for large vessels with limited generator set supplies. Fibre-optic interfacing between the MV and LV sections improves operator safety, and air insulation ensures long-term reliable operation.


In the heavy-duty world of mining, soft starters can make a huge difference to the operating life of your equipment. From crushers and mills to conveyors and pumps, AuCom soft starters have helped improve production efficiencies at mining facilities throughout the world.


AuCom soft starters can be quickly and easily integrated into an Ethernet or fieldbus network using easy-to-install interfaces. These compact interfaces plug directly onto the side of the starter or the back of the controller, allowing full control and monitoring across the network.

Separate interfaces are available for Devicenet, Ethernet/IP, Modbus, Modbus TCP, Profibus and Profinet.
