Schneider Electric ATS01N112FT Altistart 01 Soft Starter 12 A

ATS01N112FT: Altistart 01 soft starter, 12 A

The ATS01N112FT is a compact Schneider Electric Altistart 01 soft starter for asynchronous motors in simple machines. It is rated 12 A, uses a voltage-ramp start with an integrated bypass, and is only 45 mm wide, so it sits on a 35 mm DIN rail or on screws. This unit accepts a wide 110–480 V supply and offers three control voltages (110 V AC, 24 V AC/DC or 240 V AC), which makes one unit usable across several sites. Seven Star LLC supplies the ATS01N112FT in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference against the datasheet: the compatibility code is ATS01N1, the digits 112 line up with the 12 A starter rating, and the ending FT goes with the 110–480 V multi-voltage version. That is our interpretation, not a published ordering key.

Mounting, wiring and environment for the ATS01N112FT

The unit measures 124 × 45 × 131 mm and weighs 0.28 kg. It mounts on a 35 mm rail or with screws using retractable fixings, vertically within ± 10 degrees. Power terminals take 1 to 10 mm² rigid (tightening torque 1.9 to 2.5 N.m) and control terminals 0.5 to 2.5 mm² (0.5 N.m). The degree of protection is IP20, so mount it in an enclosure.

The temperature range is −10 to 40 °C without derating and up to 50 °C at 2 % per degree. Above 1000 m the current derates 2.2 % per additional 100 m. Relative humidity is 5 to 95 % without condensation, and vibration, shock and EMC data (emissions class B per CISPR 11) are listed. Certifications named are C-Tick, CCC, UL, CSA and GOST, with CE marking.

How the ATS01N112FT starts the motor

This starter raises the motor voltage along a ramp, which cuts the inrush and the starting torque shock compared with a direct-on-line start. The datasheet gives the starting torque as 30 to 80 % of the torque the motor would produce connected straight to the line, and the output voltage never exceeds the supply voltage. Once the ramp ends the integrated bypass takes the current, which is why the dissipation at full load is only 1 W while the transient state, at 61 W, is far higher. Current consumption at nominal load is listed as 60 A.

The starting time is adjustable from 1 to 5 s. The datasheet lists no deceleration time for this version, so it is a soft start only; choose a soft-stop version if the load needs a controlled stop.

Motor ratings of the ATS01N112FT

The datasheet lists these motor powers for this starter: 1.5 kW single-phase at 230 V; 2.2 kW three-phase at 230 V; 5.5 kW three-phase at 400 V. The power ranges quoted are 1.1–2 kW at 200–240 V single-phase; 2.2–3 kW at 200–240 V three-phase; 4–6 kW at 380–440 V three-phase. The wide supply range lets one type serve both 230 V and 400 V motors, with the starter current rating as the real limit. Always compare motor full-load current with the 12 A rating rather than relying on kW alone.

Technical specifications of the ATS01N112FT

Control and signalling on the ATS01N112FT

The control circuit is selectable between 110 V AC (35 mA), 24 V AC/DC (30 mA) and 240 V AC (80 mA), and the datasheet shows a control sequence with pushbuttons, protection fuses and a line contactor. Two LEDs, green and yellow, show the status. The discrete output rating is 2 A for DC-13 and 3 A for AC-15.

This version has no logic inputs or relay outputs listed in the datasheet, which keeps wiring to a minimum and is the point of the simple-machine range.

ATS01N112FT compared with other Altistart 01 ratings

The N1 versions share the multi-voltage supply and the three control voltages, while the QN versions are three-phase 380–415 V with built-in control supply and soft stop. The ATSU01N232LT from the same lane is a related 32 A unit built for a TeSys U combination.

Selecting the ATS01N112FT for Oman and the GCC

• Motor full-load current compared with 12 A and motor power with the table above.
• Supply of 110–480 V (−10 / +10 %) at your site.
• Soft stop needed? Only the QN versions list a deceleration time.
• Enclosure space of 124 × 45 × 131 mm on a rail, and the 40 °C derating point in a warm switchroom.

Typical uses are small pumps, fans, compressors and conveyors on skids and utility cabinets in Gulf plants, where a gentle start protects belts, couplings and pipework. Fit it in a ventilated cabinet because summer ambient can approach the derating limit.
