51ADX0030B - SOFT STARTER ADX0030B

Why Choose the Lovato 51ADX0030B Soft Starter?

The Lovato 51ADX0030B is a compact and dependable ADX series soft starter designed for controlled starting and stopping of three-phase asynchronous motors in industrial and commercial applications. As part of the Lovato Electric ADX...B soft starter range, it is engineered for severe-duty motor starting with reduced mechanical stress and improved control compared with direct-on-line starting.

This soft starter features an integrated bypass contactor, helping reduce heat generation and improve operating efficiency once the motor has reached full speed. Its advanced soft-start functionality helps limit inrush current, reduce voltage dips and protect connected machinery from harsh acceleration and stopping conditions.

With a rated starter current of 30 A, a three-phase rated supply voltage of 208-500 V AC and motor ratings up to 15 kW at 400 V AC or 18.5 kW at 500 V AC, the 51ADX0030B is ideal for pumps, fans, compressors, conveyors and general machinery where reliable motor starting is required.

Reliable Soft Starting for Industrial Motors

Soft starters such as the Lovato 51ADX0030B gradually increase motor voltage during start-up to limit inrush current and reduce mechanical shock. This helps protect motors, couplings, belts, pumps and driven machinery from the stress associated with full-voltage starting.

The integrated bypass contactor improves efficiency during normal operation by bypassing the power electronics once the motor is running at speed. This makes the ADX...B series suitable for industrial applications where dependable starting control, motor protection and long service life are important.

Typical Applications

• Pumps and water treatment systems.
• Fans, blowers and ventilation equipment.
• Compressors and process machinery.
• Industrial conveyors and material handling systems.
• Packaging and production machinery.
• General three-phase motor starting applications.
