More Information

Overview Manuals Specifications Brake Duty Thermal Plan Commissioning

Features:

  • Upper R1 rating with 4.0 kW and 8.8 A output
  • 127 W heat dissipation in a 70 mm-wide IP20 enclosure
  • Built-in brake chopper, macros, and Safe Torque Off
ACS355-03E-08A8-4 reaches 4 kW while retaining the narrow R1 cabinet format.

The result is a high power density for small machine panels, with integrated control and stopping functions that must be supported by a deliberate thermal and protection design.

Release documentation should prove airflow, fuse coordination, motor and cable suitability, command ownership, STO validation, braking calculations, and stable operation through the required speed range.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

  • Resistor: Select resistance, power, enclosure, and protection within ABB limits.
  • Proof test: Record DC-bus and machine response during controlled stops.

High-density R1 cooling

  • Losses: Include the documented 127 W drive dissipation in the panel study.
  • Air path: Provide 24 cubic metres per hour without hot-air recirculation.
  • Clearance: Preserve the specified top and bottom spaces around the drive.
  • Monitoring: Record cabinet temperature and loaded current during acceptance.

4 kW machine handover

  • Identity: Match the exact type code and ABB Product ID.
  • Motor model: Enter the complete nameplate and confirm the control mode.
  • Safety: Test STO channels, restart logic, and external protective functions.
  • Archive: Store accepted parameters, wiring, tests, and baseline fault records.
Description
As the highest 400 V current rating listed in frame R1, ACS355-03E-08A8-4 provides 4 kW and 8.8 A from a 70 mm-wide IP20 enclosure. The E construction is supplied with its EMC filter connected and uses a 50 Hz default frequency.

ACS355-03E-08A8-4 gives machine builders sensorless vector control, programmable I/O, application macros, Safe Torque Off, and an internal brake chopper in one compact unit. Those functions are useful where a small panel must coordinate motor speed, permissives, status, and controlled stopping.

The compact footprint of ACS355-03E-08A8-4 should not obscure its 127 W heat dissipation or 24 cubic metres per hour airflow requirement. Cabinet temperature, fuse basis, conductor routing, motor torque, stopping energy, EMC earthing, and STO proof testing all need model-specific evidence.

Technical notes
ACS355-03E-08A8-4 is the upper 400 V rating in frame R1, with 8.8 A output and 127 W documented losses. Do not reuse a lower-rating thermal or protection plan: verify 24 cubic metres per hour airflow, 20 A IEC or 25 A UL fusing, motor duty, EMC earthing, STO channels, and braking energy.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What makes ACS355-03E-08A8-4 different from the lower R1 ratings?
It retains the R1 mechanical format while reaching 8.8 A and 4 kW, with 127 W heat dissipation and a higher fuse basis. Cooling and protection therefore need a dedicated review.
How should enclosure temperature be validated for ACS355-03E-08A8-4?
Measure inlet and internal temperatures during representative load, confirm 24 cubic metres per hour airflow, inspect recirculation and neighboring losses, and apply ABB derating rules for temperature, altitude, or switching frequency.
Why can ACS355-03E-08A8-4 trip on DC overvoltage while stopping?
The load may return more energy than the selected deceleration and braking arrangement can absorb. Review inertia, regenerative torque, supply voltage, stop time, repetition, chopper limits, and resistor condition.
Can a parameter file from a smaller R1 unit be loaded into ACS355-03E-08A8-4?
Only after comparing ratings, motor data, macro, I/O, limits, ramps, control mode, STO design, braking, communications, and firmware. Preserve a rollback copy and validate under controlled load.
Which fuse decision applies to ACS355-03E-08A8-4?
ABB lists a 20 A IEC gG basis and 25 A UL Class T basis. Final coordination must also consider fault current, conductor installation, local code, selectivity, and terminal capability.
What should procurement provide when requesting ACS355-03E-08A8-4?
Include the complete type code and Product ID, motor and load schedule, stopping profile, panel environment, supply earthing, safety and control interfaces, quantity, destination, inspection scope, and delivery requirement.
