3BHB024711R0020 is a standardized three-phase power phase module exclusively manufactured by ABB for the ACS2000 medium voltage inverter, marked PBA E10 A01:6k100 on the module body. Its DC circuit integrates three 47μF capacitor units, with a net weight of 37 kg and a standard dimension of 65 cm.
As the core inverter unit of the ACS2000 6kV drive system, this module undertakes DC bus voltage stabilization and three-phase power inverter output functions. It is compatible with two mainstream ACS2000 configurations: systems equipped with sine-wave output filters and those fitted with AFE (Active Front End) rectifiers.
ABB officially confirms that all superseded legacy replacement models share fully identical mechanical hardware structures. Only certain older variants require additional mating interface cables during installation. Each module comes preloaded with dedicated factory firmware. After replacement, certified field engineers must conduct on-site flashing of matching software. This component serves as a critical spare part for emergency downtime repairs and annual preventive replacements on 6kV medium voltage inverter units.

Hardware & Technical Specifications
Hardware Structure
Integrated monolithic packaging with independent power circuits and integrated capacitor units. Adopts standard cabinet plug-in mounting design. Net weight: 37 kg; overall dimension: 65 cm. Disassembly of internal components for replacement is not required.
Capacitor Configuration
Built-in three independent 47UF filter capacitors per phase to stabilize DC bus voltage, suppress voltage spikes caused by sudden load changes, and extend the service life of power devices in the whole unit.
Compatibility
All legacy replacement modules feature identical mechanical dimensions, mounting holes and wiring terminals. Only the older model (3BHB024711R0010) requires additional matching cables when used with AFE front ends or sine wave output filters.
Firmware Matching
Each module is preloaded with dedicated control firmware, which is one-to-one bound to the main control program of ACS2000. Simple hardware replacement cannot enable normal operation; on-site reprogramming is mandatory.
Production & Delivery
Non-customized product (Made To Order: No). Brand-new genuine spare parts, individually packed per unit. Gross weight per package: 37 kg, one module per package.
Electrical Compatibility
Designed for air-cooled ACS2000 6kV medium voltage inverters. Supports direct connection to 6–6.9kV power grids, and fits constant-torque and variable-torque loads such as fans, pumps and compressors.
Applicable Industrial Scenarios
This module is matched with ACS2000 medium voltage inverters and targeted at medium and large industrial high-power drive applications:
- Cement & Building Materials: Kiln main drives, raw material mills, circulating fans, large dust removal fans
- Mining Industry: Main shaft hoists, belt conveyors, high-pressure mine drainage pumps
- Metallurgy & Steel: Blast furnace fans, auxiliary rolling mill drives, circulating water pumps
- Water & Environmental Protection: High-pressure water supply pumps for large sewage treatment plants, aeration fans, seawater desalination booster units

Frequently Asked Questions
Q1: Can model 3BHB024711R0020 directly replace the old version 3BHB024711R0010?
A1: Mechanical direct replacement is feasible, as they share identical mounting dimensions and power circuits. However, if the inverter is equipped with an AFE (Active Front End) or a sine-wave output filter, cable part 3BHB036579R0001 must be purchased and installed simultaneously. Without this cable, abnormal signal transmission will occur and the inverter will trigger a phase fault alarm.
Q2: The inverter alarms immediately after power-up following module replacement. What are the root causes?
A2: There are two primary causes:
- The factory pre-installed firmware of the new module has not been programmed on-site by an ABB certified FSE (Field Service Engineer), resulting in a mismatch between module firmware and main control software.
- The matching interface cable is omitted during replacement on legacy units, breaking the fiber-optic signal circuit.Cut off power to inspect cables, then arrange an engineer to flash the matching firmware on-site to resolve the issue.
Q3: Which key areas require focus during routine module inspections?
A3:
- Check capacitors on the module surface for bulging or electrolyte leakage;
- Inspect power copper busbar joints for overheating and oxidation;
- Ensure fiber-optic connectors are free of dust and sharp bends;
- Clear cabinet cooling air ducts of blockages to maintain proper module heat dissipation;
- Verify balanced three-phase output current during operation.
Q4: What typical alarm codes indicate aged module capacitors?
A4: DC bus overvoltage (DCOVERVOLT), unbalanced three-phase output, and phase detection faults triggered during unit startup. Severe voltage fluctuations during load deceleration that repeatedly cause overvoltage shutdowns are mostly attributed to capacity degradation of the built-in 47μF capacitors.
Q5: Can the internal 47μF capacitors be replaced separately instead of purchasing a complete module?
A5: On-site disassembly and repair are not recommended. The module adopts an integrated factory enclosure, where internal power circuits, sampling circuits and capacitors are integrally calibrated. Independent capacitor replacement will void factory insulation performance and current-sharing calibration parameters, which may easily lead to unbalanced output and breakdown of power semiconductors. ABB only supplies complete brand-new modules as official spare parts.
Q6: What environmental limits apply to module operation, and which working conditions accelerate component failure?
A6: Long-term ambient temperature above 40°C, faulty cabinet cooling fans, frequent lightning surges on the power grid, heavy-duty shock from frequent motor start-stop cycles, and heavy dust/oil contamination on-site will drastically shorten the service life of capacitors and power devices. It is advised to shut down equipment annually to clean ventilation ducts and conduct preventive module replacement every three years.
