Why Choose the Lovato 51ADX0075B Soft Starter?
The Lovato 51ADX0075B 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 a starting current of up to 5 × Ie.
This soft starter provides torque or voltage ramp starting with current limitation and incorporates an integrated bypass contactor. Motor current thermal protection, torque control, kick start, dynamic braking, a PTC input, event logging and RS232 communication provide comprehensive control and protection functionality for industrial motor systems.
With a rated starter current of 75 A, the 51ADX0075B supports IEC motor ratings of 18.5 kW at 230 V AC, 37 kW at 400 V AC and 45 kW at 500 V AC. Its three-phase 208–500 V AC operating range, integrated bypass and advanced starting functions make it suitable for severe-duty machinery and automation applications.

Controlled Starting for Three-Phase Motors
Soft starters such as the Lovato 51ADX0075B 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 provides an efficient operating arrangement after starting, while torque ramp, voltage ramp and free-wheel stopping modes provide flexibility for different motor and machinery requirements. Motor current thermal protection, PTC input, kick start, dynamic braking, event logging and RS232 communication further enhance control and diagnostic capabilities.
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.
