Lovato ADXL0045600 45 A Soft Starter with Built-in Bypass

ADXL0045600 soft starter: decoded part number

The ADXL0045600 is a 45 A soft starter from the Lovato Electric ADXL series with built-in bypass relay. It brings three-phase induction motors up to speed with a controlled ramp of torque or voltage, which reduces starting current and mechanical shock on pumps, fans, compressors and conveyors.

Decoded: ADXL is the soft starter series with a display and built-in bypass, 0045 is the rated current of 45 A and 600 is the voltage class for supplies up to 600 V AC. Sister models in the catalogue include ADXL0060600 for 60 A.

Technical specifications of the ADXL0045600

Values are taken from the Lovato Electric catalogue entry for ADXL0045600. IP00 means the unit must be installed in an enclosure.

How the ADXL0045600 works

A soft starter uses thyristors to apply a gradually rising voltage to the motor. In the ADXL the ramp can be torque based, which gives smoother acceleration of loads such as centrifugal pumps, and the current limit protects the supply from large inrush. Two phases are controlled with thyristors; once the motor is at speed, the internal bypass relay shorts the thyristors, so heat loss and fan wear are small.

The protections include motor overload with selectable trip classes at start and in run, locked rotor, current asymmetry, minimum torque (dry-run), supply faults such as phase loss or sequence error, and starter faults such as overtemperature, bypass failure and fan failure. A PTC input is available for motor thermistors.

Because the device offers a kick-start for stiff loads and dynamic braking for fast stops, one starter can cover varied duties; the display and NFC speed up parameter copying between units.

Fit in the system and related Lovato Electric parts

The ADXL sits between the basic ADXT line of soft starters and the larger frame drives, and shares its accessories such as the DIN-rail adapter EXP8003.

• ADXL0060600 and other ADXL ratings
• ADXL0085600 and ADXL0135600 for larger motors
• ADXT0034, ADXT0084 for simpler duties
• Optional accessory EXP8003 for DIN-rail mounting

Selection and ordering checklist for the ADXL0045600

Before ordering the ADXL0045600, settle the following points so that the right variant is quoted:

• Motor power and full-load current; 45 A at 400 V gives 22 kW in-line
• Supply voltage between 208 and 600 V AC and available control supply of 100 to 240 V AC
• Starting duty: pump, fan, compressor, crusher
• Ambient temperature and altitude, with derating above +40 °C
• Enclosure space for the unit and ventilation

Installation, commissioning and maintenance of the ADXL0045600

Mount vertically in a ventilated enclosure; the dimensions are 75 mm x 218 mm x 171.5 mm, and the mounting is by screws or on DIN rail with the optional adapter. Connect the control supply, power and the motor with correct phase order, then program the motor current, start ramp and protections.

At commissioning, run the motor at no load or with a light load, check the ramp, then confirm bypass operation and verify that overload class matches the motor.

• Clean the heatsink and fan area
• Check terminals for tightness
• Review the event log and counters
• Update parameters through NFC after any change

Typical applications in Oman and the GCC

Soft starters of this size are common on water-transfer pumps, cooling-water pumps, ventilation fans and screw compressors. In Gulf plants the main benefits are reduced inrush on weak supplies and less water hammer in long pipelines.

Where the enclosure temperature can exceed +40 °C, apply the stated derating of 0.5 % per °C so that the motor is not undersized.

Site conditions in Oman for the ADXL0045600

Low-voltage switching and protection devices in Oman often sit in motor control centres and outdoor panels where internal temperatures are high for much of the year. When you select the ADXL0045600, check its rated values at your real ambient temperature, as stated in the manufacturer documentation, and confirm the coordination with upstream protection and with the motor or load it serves. Short-circuit levels differ from site to site, so verify the breaking capacity required at the point of installation.

Standardising ratings and coil voltages across a project reduces the number of spare part numbers that need to be stocked. Keeping a small stock of the ADXL0045600 and recording settings such as trip ranges or ramp times shortens repair work during a breakdown.
