Description
Product Introduction
The ABB S-113N 3BHB018008R0001 is a heavy-duty Phase Module forming the core of the ACS6000 Medium Voltage Drive system (specifically within the Inverter Unit INU or Active Rectifier Unit ARU). It integrates high-power IGCTs (Integrated Gate-Commutated Thyristors), free-wheeling diodes, and snubber circuits into a single, ruggedized assembly.
This module handles phase-leg power conversion for systems ranging from 3MW to 27MW+. It is water-cooled (requiring deionized water) and mechanically designed for slide-in installation in drive cabinets. The unit typically weighs between 150 kg and 190 kg and is a direct functional peer to the S-093H, often offering updated component ratings for higher power density applications .

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Verify laser marking
3BHB018008R0001on the chassis matches the packing slip. Inspect water manifold O-ring grooves for compression set or scaling. Check fiber optic ports are sealed. - Static Parameter Test: Use a Fluke 115 / Semiconductor tester. Check IGCT Gate-Cathode junction and Diode forward voltage. Megger the HV terminals to chassis at 2500V; leakage must be <10 µA.
- Thermal Prep Check: Before installation, pressure-test the cooling circuit. Ensure the route for the deionized water loop is clear. Micro-leaks here cause HV flashovers.
- Gate Integrity: Verify the fiber link path. Although logic is in the GUSP/S-073N driver, broken fibers or dirty lenses cause “Gate Fail” alarms under load.
- Final QC & Packaging: Drain and purge with dry nitrogen if storing. Wrap the heavy alloy frame in ESD foam. Label “QC Passed – HiPot Clear” with date.
Replacement Pitfall Guide
❗ Water Quality: This S-113N module requires deionized water (Conductivity < 0.5 µS/cm). Connecting plant tap water dissolves the aluminum heat sink internally within months due to electrolysis.
❗ Busbar Torque: DC and AC connections use heavy hardware (M12/M16). Under-torquing creates hot spots that melt the laminated busbars; Over-torquing warps the ceramic IGCT housing. Use a calibrated torque wrench.
❗ Fiber Routing: The trigger fibers from the S-073N/GUSP driver are fragile. Bending radius <25mm or tight zip-ties attenuate the signal, causing intermittent misfires at high load.
❗ Cooling Flow: Verify flow rate (>12 L/min) beforeclosing the cubicle. Low flow causes thermal throttling in <3 mins at 80%+ load, potentially cracking the IGCTs from thermal shock on restart.
❗ Mechanical Seating: This is a slide-in unit. Ensure the cabinet’s spring-pressure mechanisms (for Press-Pack contact) are within spec. Weak springs = intermittent high-resistance contacts.
Keep these in mind and you’ll cut 90% of rework time.

Compatibility Matrix & Benchmarks
- S-113N (3BHB018008R0001) → S-093H (3BHB030478R0309): Direct/Compatible — Usually interchangeable phase-leg hardware in ACS6000 INU, but verify busbar hole patterns and cooling manifold alignment as S-113N is often a higher-density update.
- S-113N → ABB ACS6000 INU Cabinet: Direct Fit — Designed for standard INU/ARU slide rails.
- S-113N → Standard IGBT Module: Incompatible — Requires ABB specific GUSP (S-073N) gate drivers and fiber-optic timing.
- Switching Speed: < 10 µs (IGCT Turn-off)
- Efficiency: > 98% (System Level)
- Isolation: 2500 V+ (HV Terminal to Heatsink)
