ACS355-03E-08A8-4 4kW Machinery Drive 380-480V IP20 R1 | ABB

The Original New ABB ACS355-03E-08A8-4 is a 4 kW (5.5 HP) machinery drive from the ABB ACS355 series, engineered for reliable motor control in light industrial and OEM machinery applications. Rated at 8.8 A with a 380–480 V three-phase input, this compact drive delivers efficient speed and torque control for pumps, fans, conveyors, compressors, and other small machinery. Featuring an IP20 enclosure, integrated Category C3 EMC filter, built-in brake chopper, and Safe Torque Off (STO) safety function as standard (SIL3 / PLe), the ACS355-03E-08A8-4 simplifies installation and reduces the need for external components. The drive is part of the ABB machinery drive portfolio and includes scalar and sensorless vector control modes, support for both induction and permanent magnet motors, and an 8-step built-in sequencer (16-step optional) for machine automation without an external PLC. Its compact R1 frame size and lightweight 1.2–2.5 kg design makes it suitable for a wide range of OEM and machinery applications.
