Why Choose the Lovato 51ADX0245B Soft Starter?
The Lovato 51ADX0245B 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 51ADX0245B 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 management functions include motor current thermal protection, torque control, kick start, dynamic braking, PTC input, event logging and RS232 communication.
With a rated starter current of 245 A and a three-phase 208–500 V AC supply, the 51ADX0245B supports IEC motor ratings of 75 kW at 230 V AC, 132 kW at 400 V AC and 160 kW at 500 V AC. Its integrated bypass contactor, forced cooling system and built-in LCD interface make it suitable for demanding high-power 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 51ADX0245B 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, while forced cooling supports operation in demanding applications. Functions including current limitation, motor current thermal protection, torque control, kick start, dynamic braking, PTC monitoring and event logging provide comprehensive motor management for industrial machinery and process equipment.
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.
- High-power three-phase motor applications requiring controlled acceleration and reduced starting stress.
