The ABB ACS355-03E-03A3-4 is an ACS355 machinery drive rated 1.1 kW (1.5 hp) with a continuous output current of 3.3 A on a 3-phase 380-480 V supply, in frame size R1. The “E” in the type code means the internal EMC filter is connected and the default motor frequency is 50 Hz.
The ACS355 is the compact ABB drive built for machine builders: packaging, food processing, material handling, textile and printing machines. It has Safe Torque Off (SIL3) as standard, a built-in brake chopper, speed and torque control and a pulse-train input, and accepts plug-in fieldbus adapters.
For troubleshooting see our ABB inverter fault codes guide (Arabic).

Compatibility and replacement
The U variant (ACS355-03U-…) is the same hardware with the EMC filter disconnected and 60 Hz default. If you need IP66 or a different variant, send us the type code from the old drive label.
Frequently asked questions
What is the difference between ACS355-03E and -03U?
Per ABB: E has the EMC filter connected and 50 Hz default; U has the filter disconnected and 60 Hz default. The filter can be connected later if required.
Does it have Safe Torque Off?
Yes. STO (SIL3) is standard on the ACS355, so emergency stop can be implemented without a motor contactor.
