Why Choose the Lovato 51ADX0310 Soft Starter?
The Lovato 51ADX0310 is an advanced three-phase soft starter designed for controlled starting and stopping of asynchronous three-phase motors in severe-duty industrial applications. As part of the Lovato Electric ADX soft starter series, it is rated for starting currents up to 5 × Ie and is specifically predisposed for use with an external bypass contactor.
The 51ADX0310 provides three-phase control with torque or voltage ramp starting and adjustable current limitation. It also supports torque-ramp, voltage-ramp and free-wheel stopping, together with motor thermal overload protection, torque control, kick start, dynamic braking, PTC motor protection and extensive supply, motor and starter protection functions.
With a rated starter current of 310 A and a three-phase 208–415 V AC rated supply, the 51ADX0310 has IEC motor ratings of 90 kW at 230 V AC and 160 kW at 400 V AC. Forced cooling and provision for an external bypass contactor make it suitable for demanding high-power motor-starting applications.

Advanced Soft Starting for Industrial Motors
Soft starters progressively control the electrical power supplied to a motor during acceleration, helping reduce the high starting current and mechanical stress associated with direct-on-line starting. The Lovato 51ADX0310 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 51ADX0310 is predisposed for connection to an external bypass contactor rather than incorporating an internal bypass. Its protection functions cover conditions including supply phase loss, phase sequence errors, voltage and frequency limits, motor overload, locked rotor, current asymmetry, overcurrent and starter overtemperature.
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 external bypass arrangements.
