Schneider Electric ATS22D47Q Altistart 22 Soft Starter 47 A

ATS22D47Q: Altistart 22 soft starter for pumps and fans, 47 A

The ATS22D47Q is a Schneider Electric Altistart 22 soft starter for three-phase asynchronous motors, with the datasheet naming pumps and fans as the application. It is rated 47 A in the motor supply line, drives 11 kW at 230 V; 22 kW at 400 V and 440 V, and has a 230 V control circuit. This unit is a lifecycle-flagged product: the datasheet shows the status “To be discontinued on 31 Dec 2026”, with end of service planned for 29 Jun 2035, so confirm availability and plan a replacement path before committing it to a new design. Seven Star LLC supplies the ATS22D47Q in Oman and the GCC as an independent supplier based in Muscat.

The reference breaks down in a way that matches the datasheet: ATS22 is the range, D marks the 230 V control version, the digits (47) follow the starter rating of 47 A, and Q goes with the 230–440 V power supply. This is our reading, not a published ordering key.

ATS22D47Q compared with the other ATS22 ratings in this group

All four share the 230 V control circuit, the torque-controlled start and the Modbus link. The ATS490 soft starters covered on neighbouring pages are a different family with a different supply and control arrangement.

Selection checklist and use of the ATS22D47Q in Oman and the GCC

• Motor full-load current compared with 47 A, and the connection (line or delta) your wiring uses.
• Power supply of 230–440 V and a 230 V control supply available at the panel.
• Lifecycle status: to be discontinued on 31 dec 2026; check stock and a replacement plan.
• Cabinet space for 265 × 130 × 169 mm and enough ventilation for 48 W of loss.
• A type 12 or IP54 cabinet where dust is heavy.

This starter suits pumps and fans, for example water transfer, cooling and ventilation duty in Gulf plants, where gentle acceleration limits pipe surges and belt wear. Dusty sites need a filtered cabinet.

Torque-controlled starting on the ATS22D47Q

This unit starts the motor by torque control with the current limited to 3.5 times the nominal current, rather than by a plain voltage ramp. The output current can be set between 0.4 and 1 times the starter rating, and the factory setting for this reference is 42 A, so the first commissioning step is to adjust it to the motor nameplate. An internal bypass takes over at the end of the start, and the datasheet gives 48 W of dissipation for standard applications.

Connection is either in the motor supply line or to the motor delta terminals. The AC-3 power table in the datasheet gives 7–11 kW at 200–240 V; 15–25 kW at 380–440 V. Confirm the connection method with the motor terminal box layout.

Mounting and heat for the ATS22D47Q

This is a frame size A unit measuring 265 × 130 × 169 mm with a weight of 7 kg. Mount it within ± 10 degrees of vertical, leave free space so air can move from bottom to top, keep it away from heat-radiating parts, and arrange several starters in a row rather than stacking them, because heat from the lower unit raises the temperature around the upper one. Cooling is by forced convection, and the datasheet gives the noise level as 45 dB.

Ambient is −10 to 40 °C without derating and 40 to 60 °C with 2.2 % derating per degree. Altitude up to 1000 m is free of derating, with 2.2 % per additional 100 m up to 2000 m. The datasheet states pollution degree 2 and advises a type 12 or IP54 cabinet for pollution degree 3, which matters in dusty Gulf plants. Vibration, shock and EMC data (emissions level A) are listed, with certifications C-Tick, CCC, UL, CSA and GOST and CE marking.

Control, protection and communication on the ATS22D47Q

The control circuit runs from 230 V and draws 20 W. Two relay outputs, R1 and R2, can be assigned to running, alarm, trip, stopped, not stopped, starting or ready, rated 5 A at 250 V AC (resistive) or 2 A inductive. Three logic inputs (LI1 to LI3) work at 24 V, and a PTC probe input of 750 Ω brings in motor temperature. The datasheet lists protection against line phase failure and thermal protection of both the motor and the starter.

A Modbus RS485 multidrop link on an RJ45 connector runs at 4800, 9600 or 19200 bps and supports 31 installed devices, so the starter can be read or controlled from a PLC. The datasheet’s mounting pages require the starter to be fitted in an enclosure, since ATS22 units are open devices.
