Schneider Electric ATS01N103FT Altistart 01 Soft Starter 3 A

ATS01N103FT: Altistart 01 soft starter, 3 A starter rating, 110–480 V

The ATS01N103FT is a soft starter from the Schneider Electric Altistart 01 range for asynchronous motors on simple machines. It limits the stress of direct-on-line starting by raising the motor voltage along a ramp, and it carries an integrated bypass that takes over at the end of the start. The datasheet gives a starter rating (IcL) of 3 A and a rated supply voltage of 110–480 V −10/+10 %. This is the compact 23 mm wide member of the pair, sized for motors up to about 1.1 kW at 400 V. Seven Star LLC supplies the ATS01N103FT in Oman and the GCC as an independent supplier based in Muscat.

In the reference, ATS01 is the range and device short name, N1 appears in the compatibility code ATS01N1, and the number 103 or 109 follows the starter rating of 3 A or 9 A in our reading; FT is part of the manufacturer’s code. The datasheet remains the authority for ordering.

Selection checklist for the ATS01N103FT

• Confirm the motor power and voltage against the table: 0.37 kW, 3 phases at 230 V; 0.55 kW, 3 phases at 230 V; 1.1 kW, 3 phases at 400 V; 0.37 kW, 1 phase at 230 V.
• Check the control supply: 24 V AC/DC, 110 V AC or 240 V AC versions are listed in the control circuit data.
• Plan the surrounding devices: motor circuit-breaker, line contactor and control fuses as in the datasheet example.
• Check the ambient temperature and altitude against the derating rules.
• Confirm the duty is a simple machine start, not a frequent or heavy-duty application.

Typical uses of the ATS01N103FT in Oman and the GCC

ATS01N103FT suits small pumps, fans, conveyors and gates up to about 1.1 kW where a gentle start reduces mechanical shock and inrush on a weak feeder. In Oman and the GCC that includes building services, small water-treatment skids, irrigation pumps and workshop machines. The ambient limit of 40 °C without derating is the key figure for the region: a starter in a closed cabinet in the sun will need the 2 % per °C derating above 40 °C, so size accordingly or ventilate. Frequent start-stop cycles generate heat in the ramp phase, which the simple machine category does not cover.

How the ATS01N103FT starts a motor

The type of start is a voltage ramp. Two rotary adjusters on the front set the start time and the initial voltage, and the datasheet states that the start time is adjustable from 1 to 5 s and that starting torque lies between 30 and 80 % of the torque the motor would develop connected directly to the line. Raising the initial voltage gives more torque on a stiff load; lowering it gives a softer pull-away for belts, fans and small pumps. Two LEDs indicate the status: green for power on and yellow for full voltage.

The power dissipation is quoted as 19 W in transient state and 4 W at full load and at end of starting, a reminder that the heat is produced mainly during the ramp and is small once the bypass is closed. This unit also lists a discrete output rated 2 A DC-13 and 3 A AC-15, and a control circuit voltage that depends on the version of the control supply: 110 V AC ± 10 % at 30 mA; 24 V AC/DC ± 10 % at 25 mA; 240 V AC ± 10 % at 65 mA.

ATS01N103FT technical specifications

Installation and environment of the ATS01N103FT

The housing measures 23 × 100 × 100 mm and weighs 0.16 kg. It is mounted on a symmetrical 35 mm rail, or on an asymmetrical rail with the adaptor RHZ 66, in a vertical position within ±10 degrees. The datasheet’s example for a three-phase supply shows a motor circuit-breaker (Q1), a line contactor in the sequence (KM1), control protection fuses (F1, F2) and start and stop pushbuttons (S1, S2) around the starter. Tightening torque is listed as 0.8 N.m.

The ambient temperature is −10–40 °C (without derating) without derating and 40–50 °C (with current derating of 2 % per °C); storage is −25–70 °C conforming to EN/IEC 60947-4-2. Altitude up to 1000 m needs no derating, and above it the current is derated by 2.2 % per additional 100 m. Relative humidity is 5–95 % without condensation, protection is IP20, pollution degree 2, and vibration and shock are 1 gn (13–150 Hz) and 15 gn for 11 ms. Certifications listed are CSA, GOST, C-Tick, UL and CCC with the CE marking, and the product standard is EN/IEC 60947-4-2.

Motors the ATS01N103FT is rated for

The datasheet lists these motor powers: 0.37 kW, 3 phases at 230 V; 0.55 kW, 3 phases at 230 V; 1.1 kW, 3 phases at 400 V; 0.37 kW, 1 phase at 230 V. In horsepower terms they are 0.5 hp, 3 phases at 230 V; 0.5 hp, 3 phases at 460 V; 1.5 hp, 3 phases at 460 V. The corresponding power ranges are 0–0.5 kW at 200–240 V 1 phase; 0–0.5 kW at 200–240 V 3 phases; 0.55–1 kW at 200–240 V 3 phases; 1.1–2 kW at 380–440 V 3 phases. The line current figure given is 15 A at nominal load, the supply frequency 50–60 Hz – 5–5 % (network range 47.5–63 Hz) and the output voltage is at most the supply voltage. For loads beyond this size the larger sibling ATS01N109FT is the next step, rated 9 A.

Altistart 01 ATS01N1 pair: ATS01N103FT and ATS01N109FT

Both references share the 110–480 V supply range, the voltage-ramp start and the integrated bypass. They differ in current rating, motor size, housing and terminal type.
