The '03E' prefix places it on the 400 V class; the trailing -4 confirms the 3-phase 400/480 V input. Output voltage mirrors the input range at 0 … 400/480 V AC 3-phase, with a programmable output frequency of 0 … 599 Hz — wide enough to cover induction motors, high-speed spindles, and low-speed high-torque constant-torque loads running below line frequency. ## Mechanical and thermal envelope Cabinet footprint is 161 x 70 x 239 mm — the narrow R0-class column ABB uses for the smallest ACS355 frames — and the module installs as a cabinet-build component rather than a wall-mount unit. IP20 means it lives inside a closed enclosure; don't plan on a drip-prone or dusty panel without the appropriate sealed cubicle. Maximum ambient rating is 40 °C, the headline figure for cabinet ventilation design; above that the drive's standard ABB derating applies per the published curves. ## Onboard I/O and control wiring Onboard I/O is the standard ACS355 micro-drive complement: 2 analog inputs, 1 analog output, 5 digital inputs, and 1 digital output. For a 0.37 kW pump, fan, or small conveyor that's enough to land run/stop, a speed reference, and a fault relay without an external I/O card. ## Same-frame second source at the same kW rating Within the ACS355 family the closest functional second-source is the ACS355-03E-01A9-4 — same 0.37 kW slot, output current one step up at 1.9 A. It drops into the same R0 frame footprint, so a panel specified around the -01A2-4 accepts the -01A9-4 mechanically without rewiring or backplate rework; only the parameter set and motor nameplate match need to be re-entered at commissioning.","metaTitle":"ABB ACS355-03E-01A2-4 Inverter Drive, 0.37 kW, 1.2 A, 400/48","metaDescription":"ABB ACS355-03E-01A2-4 ACS355-series inverter drive, 0.37 kW / 1.2 A output on 400/480 V 3-phase, IP20 cabinet module.
