Why Choose the Lovato 51ADX0045B Soft Starter?
The Lovato 51ADX0045B 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 series, it is designed for severe-duty starting applications with starting current up to 5 × Ie.
This soft starter provides torque or voltage ramp starting with current limitation, together with an integrated bypass contactor. Once the motor has completed its start, the built-in bypass helps minimise power dissipation, while integrated motor and starter protection functions support dependable operation in industrial motor-control systems.
With a rated starter current of 45 A, the 51ADX0045B supports IEC motor ratings of 11 kW at 230 V AC, 22 kW at 400 V AC and 30 kW at 500 V AC. Its three-phase 208–500 V AC operating range, adjustable current limitation and comprehensive protection functions make it suitable for demanding machinery and automation applications.

Controlled Starting for Three-Phase Motors
Soft starters such as the Lovato 51ADX0045B progressively control motor starting rather than applying full supply voltage immediately. Its torque or voltage ramp starting modes with current limitation provide controlled acceleration for asynchronous three-phase motors and help manage starting current in severe-duty industrial applications.
The integrated bypass contactor reduces power dissipation once the motor reaches normal operating conditions, while torque ramp, voltage ramp and free-wheel stopping modes provide flexibility for different machinery requirements. Motor overload protection, PTC input, phase monitoring, locked-rotor protection and other integrated functions further support reliable motor operation.
Typical Applications
- Industrial pumps and pumping systems.
- Fans and ventilation equipment.
- Compressors and process machinery.
- Conveyors and material handling systems.
- Industrial production machinery.
- Three-phase asynchronous motor systems requiring severe-duty starting.
