Solcon soft starters are designed for smooth continuous start and stop of induction motors what significantly reducing start-up current and network disruption. By controlling the start and stop, we can fine-tune the motor and load to prevent mechanical overloads, such as water shocks, excessive belt tension, and excessive torque on couplings and shafts. Solcon's soft starters also work flawlessly in unstable power grids, making them suitable for use in mines, shipbuilding, plumbing and industry.


iStart is the latest and most advanced Solcon digital soft starter, with integrated bypass contactor and three phase control. Compact and versatile units incorporate the most sophisticated start and stop features to provide the best solutions for a wide variety of applications. An extensive range of motor protections, however, enables long-term and reliable operation.
