ADXT013924 Lovato SOFT STARTER 139A 380-690V, AUX 24VAC/DC

Why Choose the Lovato ADXT013924 Soft Starter?

The Lovato ADXT013924 is an advanced three-phase soft starter designed for controlled starting and stopping of asynchronous motors in standard and heavy-duty industrial applications. As part of the Lovato ADXT soft starter series, it combines three-phase control, integrated motor protection and advanced starting functions to help reduce electrical starting currents and mechanical stress on motors and driven equipment.

The ADXT013924 features an integrated bypass relay that reduces power consumption and heat generation once the starting ramp has been completed. It supports both conventional in-line and inside-delta motor connections, while its graphic LCD display provides a convenient interface for configuration, monitoring and diagnostics.

With a rated starter current of 139 A and a three-phase 380–690 V AC supply, the ADXT013924 is suitable for substantial industrial motors and demanding high-inertia loads. It is rated for motors up to 75 kW at 400 V with an in-line connection and up to 110 kW at 400 V with an inside-delta connection, while its 24 V AC/DC auxiliary supply supports straightforward integration into modern industrial control systems.

Controlled Starting for Demanding Industrial Motors

Soft starters progressively control the power supplied to an AC motor during acceleration, helping limit starting current and reducing mechanical shock compared with direct-on-line starting. The Lovato ADXT013924 uses three-phase control to provide strong starting performance, making it particularly suitable for demanding applications characterised by high inertia or significant starting torque requirements.

The ADXT series provides multiple starting and stopping modes together with integrated diagnostic and protection functions. Once the starting ramp is complete, the built-in bypass relay reduces losses and heat generation, while support for in-line and inside-delta connections gives system designers additional flexibility when matching the starter to the motor and application.
