ACS355-03E-12A5-4 5.5kW Machinery Drive 380-480V IP20 R3 | ABB

The Original New ABB ACS355-03E-12A5-4 is a 5.5 kW (7.5 HP) machinery drive from the ABB ACS355 series, engineered for reliable motor control in light to mid-range industrial and OEM machinery applications. Rated at 12.5 A with a 380–480 V three-phase input, this compact drive delivers efficient speed and torque control for conveyors, packaging machines, material handling equipment, gates and barriers, compressors, and bottling lines. Featuring an IP20 enclosure, integrated EMC filter, built-in brake chopper, and Safe Torque Off (STO) safety function as standard (SIL3 / PLe), the ACS355-03E-12A5-4 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 R3 frame size makes it suitable for a wide range of OEM and machinery applications.
