ACS350-03E-02A4-4 application brief: motor matching and drive commissioning
ACS350-03E-02A4-4 is an ABB general machinery drive designation in the three-phase 380–480 V family. The code identifies a small current-rated frame, but the motor power that can be controlled depends on ABB's rating table, overload duty, supply conditions and ambient derating. Keep ACS350-03E-02A4-4 as the exact reference when checking the drive nameplate and replacement fit.

Identification note: ACS350-03E-02A4-4. The figures above are selection references; verify the actual label, duty rating, approvals, firmware and options for the exact unit before purchase or engineering release.
ACS350-03E-02A4-4 must be matched to the actual duty and interface; confirm the nameplate before ordering.
Related model references
Use ACS350-03E-02A4-4 for machine motion where an adjustable motor speed is required, such as small conveyors, fans, mixers or OEM machinery. Confirm whether the load needs constant torque, variable torque, frequent starts, braking or low-speed thermal management. A drive is not a softstarter: it provides continuous speed control and has different wiring and protection requirements.
Review motor current and voltage, overload profile, acceleration time, control I/O, EMC category, braking needs and communication options for ACS350-03E-02A4-4. Check the exact frame, enclosure, external filters and upstream protection with current ABB documentation. Do not extrapolate a single rating from a neighboring 02A4 or other voltage variant.
Before replacement, compare ACS350-03E-02A4-4 with the installed revision, accessories, wiring and engineering configuration.
