Why Choose the Lovato 51ADX0142B Soft Starter?
The Lovato 51ADX0142B is an advanced three-phase soft starter designed for controlled starting and stopping of asynchronous three-phase motors in demanding industrial applications. As part of the Lovato Electric ADX...B soft starter series, it is designed for severe-duty operation with a starting current of up to 5 × Ie and incorporates an integrated bypass contactor.
The 51ADX0142B provides three-phase control with torque or voltage ramp starting and current limitation. Multiple stopping modes include torque ramp, voltage ramp and free-wheel stopping, while motor protection functions include starting and running overload protection, locked-rotor detection, current asymmetry monitoring, minimum-torque protection and overtemperature protection.
With a rated starter current of 142 A and a three-phase 208–500 V AC supply, the 51ADX0142B supports IEC motor ratings of 37 kW at 230 V AC, 75 kW at 400 V AC and 90 kW at 500 V AC. Its integrated bypass contactor, forced cooling system and built-in LCD interface make it suitable for demanding industrial motor-starting applications.

Advanced Soft Starting for Industrial Motors
Soft starters progressively control the electrical power supplied to a motor during acceleration, helping to reduce the high starting current and mechanical stress associated with direct-on-line starting. The Lovato 51ADX0142B provides three-phase control with configurable torque or voltage ramp starting, allowing acceleration to be matched to the requirements of the motor and driven equipment.
The integrated bypass contactor carries the motor current after the starting sequence is complete. Motor protection functions include overload protection during starting and running, locked-rotor detection, current asymmetry monitoring, minimum-torque protection and overtemperature monitoring, while additional starter protection helps safeguard the soft starter itself.
Typical Applications
- Industrial pumps and pumping systems.
- Fans, blowers and ventilation equipment.
- Conveyors and material handling systems.
- Compressors and industrial machinery.
- Heavy-duty production and processing equipment.
- Three-phase motor applications requiring controlled acceleration and reduced starting stress.
