ABB ACS355-03E-05A6-4 Variable Frequency Drive

The ABB ACS355-03E-05A6-4 Variable Frequency Drive is a 2.2 kW inverter designed for industrial motor control of three-phase machines, delivering precise speed and torque regulation across conveyors, pumps, fans, mixers, packaging machinery, and material handling equipment. It accepts three-phase AC input and provides variable-frequency three-phase AC output, with V/Hz control and advanced options, plus built-in standard communications such as Modbus/RTU for panel or cabinet installations in automation systems. With protection features including overload, short-circuit, overvoltage, and undervoltage protection and an IP20-rated enclosure, the ACS355-03E-05A6-4 supports panel builds, system upgrades, retrofit projects, and replacement of legacy or failed drive modules within production lines. Common replacements include ABB ACS355-03E-04A8-4, Schneider Electric Altivar 312 2.2 kW, and Siemens SINAMICS V20 2.2 kW drives.
