ABB 3BHB009884R0002 PHASE MODULE (S‑073H) FOR 7 MV, HIGH IM
Product Description
3BHB009884R0002 (S‑073H) is a dedicated phase module for ABB ACS6000 medium‑voltage drive system. Developed for 7MVA power level and high‑current operating conditions, it adopts IGCT power devices with integrated water‑cooled structure. As the core power conversion unit, it performs electric energy conversion and output, and is widely deployed in large‑scale industrial medium‑voltage drive equipment.
This phase module undertakes single‑phase AC‑DC‑AC power conversion. Multiple S‑073H modules are combined inside the complete drive unit to realize three‑phase drive output. It is a frequently‑replaced power component for field spare parts, mostly used for maintenance and retrofitting of legacy medium‑voltage frequency converters.
Core Performance Advantages
3BHB009884R0002 phase module integrates power semiconductors, water‑cooled flow channels, high‑voltage insulated busbars and snubber capacitor assemblies to complete voltage and current conversion. Firstly, high‑current withstand design specially matches heavy‑output‑current conditions of 7MVA units and improves stability under heavy‑load operation. Secondly, integrated water‑cooled heat dissipation structure closely fits cooling channels with power semiconductors to rapidly remove heat generated during high‑power operation and reduce thermal breakdown risks. Thirdly, modular rack‑mounted structure supports quick on‑site assembly and disassembly to shorten equipment downtime for maintenance. Fourthly, redundant high‑voltage insulation design meets insulation requirements of medium‑voltage systems and reduces creepage and discharge faults. Fifthly, it is compatible with Direct Torque Control (DTC) algorithm, cooperating with main controller to realize high‑precision motor speed and torque regulation.
Product Features
The unit adopts welded metal rack construction, equipped with high‑voltage copper conductive busbars, water‑cooled pipe interfaces and transparent protective cover. Internally integrated components include IGCT devices, snubber circuits and sampling sensor terminals. 3BHB009884R0002 is a complete assembled power unit without scattered assembly; users can perform direct whole‑unit replacement upon delivery. Built‑in status acquisition points feed temperature and device status signals back to drive main control board for system fault pre‑warning. High mechanical strength enables operation under industrial vibration and dusty environments. Standard sealing structure for water‑cooled pipe joints minimizes water‑leakage risks.
Working Principle
As the single‑phase power conversion carrier for ACS6000 drive, 3BHB009884R0002 receives trigger pulse signals from control system and controls on‑off status of internal IGCT semiconductors, converting DC bus voltage into AC voltage with adjustable amplitude and frequency. Circulating cooling water continuously removes heat from power devices via water‑cooled loop. Snubber capacitors absorb transient switching peak voltage to protect semiconductors. Built‑in sensing circuits collect module temperature and device operating status and feed data back to main controller. Three S‑073H phase modules work together to output three‑phase adjustable AC power for driving large‑power medium‑voltage motors.
Application Scenarios
3BHB009884R0002 is matched with ACS6000 medium‑voltage variable‑speed drives for high‑power high‑voltage motor speed regulation. It is widely applied in metallurgical rolling mill main drives, large‑mining ball mills, petrochemical large compressors, power‑plant boiler induced‑draft fans, cement main drive motors and high‑power paper machine drives. It serves heavy‑industry production lines requiring continuous non‑stop operation with high downtime loss.
Product Comparison
Compare with the same‑series S‑073N phase module: S‑073N corresponds to lower power grade with smaller current rating. 3BHB009884R0002 (S‑073H) is upgraded for 7MVA high‑current units with enlarged busbar cross‑section, improved water‑cooled flow capacity, upgraded IGCT components and higher insulation level. It is exclusively designed for 7MV HIGH IM units and cannot be directly used for lower‑power S‑073N equipment. S‑093H applies to higher‑power ACS6000 devices with larger dimension and weight and cannot replace 3BHB009884R0002 directly. Modules with different suffixes have similar physical appearance but differ in internal power devices and busbars; random interchange is forbidden.
Matching Components
3BHB009884R0002 phase module needs to cooperate with below components within complete system:
- ACS6000 7MVA complete cabinet; 3 pieces of 3BHB009884R0002 for three‑phase power output

FAQ
Q1: Can 3BHB009884R0002 directly replace S‑073N module?
A1: No. S‑073N is for lower power grade. 3BHB009884R0002 is dedicated 7MV high‑current version with different internal power devices and busbar specifications. Forced replacement will cause overcurrent damage.
Q2: How many pieces of 3BHB009884R0002 are required for one ACS6000 7MV drive?
A2: One three‑phase unit requires 3 pieces of 3BHB009884R0002 for phase A/B/C respectively.
Q3: Is hydrostatic leak test needed after module delivery?
A3: Simple water‑pressure leak test is recommended before field installation to avoid secondary damage caused by water leakage during operation.
Q4: Is 3BHB009884R0002 discontinued?
A4: New complete‑set production has been stopped. All market supplies are replacement spare parts with limited stock. Advance stock‑up is suggested.
Q5: Key installation notes for S‑073H phase module?
A5: Tighten conductive busbar bolts according to torque value in manual; do not omit water‑cooling pipe sealing rings; ensure DC bus is fully discharged before wiring.
Q6: Does intact appearance guarantee healthy internal IGCT?
A6: Good appearance cannot confirm device integrity. IGCT internal breakdown leaves no visible trace. Power‑on test is mandatory for verification.
Q7: Can I purchase separate IGCT components for on‑site repair?
A7: On‑site disassembly and repair are not recommended. Modules are factory‑calibrated. Disassembly may damage water‑cooling sealing and insulation performance. Whole‑unit replacement is preferred.
Q8: How to confirm 3BHB009884R0002 is the correct spare part for my equipment?
A8: Check cabinet nameplate and old module label, confirm marking “7MV HIGH IM” and part number 3BHB009884R0002 before order placement.
