ABB ACS380-040S-25A0-2 Machinery Drive 5.5 kW 25 A
Description
What the ACS380-040S-25A0-2 is
ABB’s catalogue lists the ACS380-040S-25A0-2 as an ACS380 module-type drive for a 3-phase 200 to 240 V network. Nominal output is 25 A at 5.5 kW, in frame R3. It suits compressors and mid-power machine axes. ABB supplies it as the standard variant (I/O and Modbus, BMIO-01 module fitted), with the low filtering level (C3 filter on 400 V, no internal filter on 230 V).

Current ratings of the ACS380-040S-25A0-2
Duty class decides the column: 24.2 A (5.5 kW) for light-overload loads, 17.5 A (3.7 kW) for heavy-duty loads, and a peak of 31.5 A. Light-overload use allows 110% of the current for one minute in ten, heavy duty 150%, both at 50 degrees C. The catalogue gives UL horsepower ratings at 208/230 V and 480 V in its ratings tables. Start from the motor nameplate current rather than the kilowatt figure.
Branch protection in the catalogue is 50 A gG or 80 A gR (IEC) and 40 A class T (UL). The UL input current is 35.1 A, and the Type E manual motor protector named is MS165-42. Heat loss is 182 W (620 BTU/h); note that air flow 128 m3/h (75 ft3/min), maximum sound level 66 dBA.
Dynamic braking uses the integrated chopper. Choose a resistor between 16 and 28 ohm; the rating is 5 Hp continuous and 8 kW maximum. Cranes, hoists and high-inertia fans can stop quickly without extra hardware.
Type code and option codes
The designation splits into ACS380, 04 for module, 0 for the EMC filter level, S for connectivity, 25A0 for size and 2 for voltage class. The letter S adds the BMIO-01 module with I/O and Modbus RTU, N leaves the extension slot empty and C is the configured variant. Plus codes such as +L515 for the BIO-01 I/O extension, +R700 for an English printed manual, +K451 for FDNA-01 DeviceNet apply to the C variant only.
Ambient limits are -10 to +50 degrees C (60 with derating on frames R1 to R4) and 5 to 95% humidity without condensation. Altitude is 0 to 4000 m for 400 V units and 0 to 2000 m for 200 V units, with derating above 1000 m. The standard motor cable limit is 150 m, longer with an output choke.

Supply and DC link
The -2 at the end of the type code means a three-phase 200 to 240 V supply (+10%/−15%, 50/60 Hz ±5%). ABB’s catalog gives a common DC connection level of 270 to 325 V ±10% for the 200 V types, with an internal charging circuit, so several drives on one machine can share a DC bus. This 25 A drive is a frame R3 unit: 205 mm mounting height, 169 mm wide, 174 mm deep and about 2.9 kg.
Default I/O connection (ABB standard macro)
- +24 V DC auxiliary output, maximum 250 mA.
- DI1 stop/start, DI2 forward/reverse, DI3 and DI4 speed selection, plus a ramp set selection input.
- Analog input for the speed reference (0 to 10 V) and an analog output for output frequency (0 to 20 mA).
- Digital output for ready to run, and a fault relay output rated 250 V AC / 30 V DC, 2 A.
- Embedded Modbus RTU (EIA-485).
- Safe Torque Off terminals, connected at the factory; the drive starts only when both circuits are closed.
Extension, feedback and safety
One option slot on the side of the drive accepts BAPO-01 external 24 V DC (+L534), BREL-01 four-relay extension (+L511), BIO-01 I/O extension for use with fieldbus modules (+L515), or BTAC-02 encoder interface with external 24 V DC (+L535) for TTL and HTL pulse encoders. The built-in STO meets IEC 61508 ed2 SIL 3, IEC 61511 SIL 3, IEC 62061 SIL CL 3 and EN ISO 13849-1 PL e.
Documents and quotation
The figures above come from the ABB ACS380 machinery drives catalogue (US edition, Rev E, linked here) and the ABB product page for the ACS380-040S-25A0-2. Seven Star LLC supplies the ACS380-040S-25A0-2 on request from Muscat; availability and lead time are stated in the quotation.
Before ordering, check the exact code, option codes, motor current, braking duty and site conditions. The catalogue is a US edition, so cross-check IEC values against ABB hardware manual 3AXD50000029274. More drive sizes sit in AC drives, and the ABB ACS580 page introduces the wall-mounted range.

About brand
ABB is the Swiss-Swedish engineering group for electrification and automation: low voltage drives, motors, circuit breakers and motor control, process instruments and analysers, control systems and robots. It was formed on 5 January 1988 by the merger of two older companies. ASEA was founded in Västerås, Sweden, in 1883 by Ludvig Fredholm to make electric lighting and generators.

Choosing an ABB drive
ABB's ACS drive codes are easy to read once you know the pattern. In ACS580-01-046A-4, "ACS580" is the drive family, "01" means a wall-mounted single drive, "046A" is the rated output current (about 46 A) and "-4" means a 380–480 V supply. The family is chosen by application: ACS355 for compact machinery, ACS310 for simple pumps and fans, ACS580 as the general-purpose drive, ACQ580 for water and wastewater with pump functions such as pipe fill and dry-run protection, and ACS880 for heavy industrial duty with direct torque control. Size the drive on the motor's full-load current, not only its kW rating, and allow derating for the high ambient temperatures common in Gulf electrical rooms.
Where ABB products are used
In Oman and the GCC, ABB drives and motors run pumps, fans and compressors in water and wastewater plants, district cooling, oil and gas and industry. ABB flowmeters, level instruments and analysers are used in water utilities, power and desalination plants and refineries, and SACE breakers protect switchboards in buildings and plants.
