4. Product Introduction
The ABB 3BHB005245R0101 is a subboard printed circuit assembly used internally in ABB industrial automation and control systems. Designated KU C755 AE, this board functions as a protective, varnished submodule that integrates into larger control modules, power electronics assemblies, or drive electronics.
Compact and lightweight (~95 g), this PCB assembly is manufactured to ABB standards and can serve as a replacement subcomponent in equipment repair, refurbishment, or OEM builds. It replaces older codes like HB005245R0101 and is stocked as New Original or New Surplus for system maintenance and continuity.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Device fails to power up | PCB subboard not seating or missing | ⚠️ Medium | Verify board sits fully in its slot and connectors | Reseat subboard; check adjacent board connections |
| Intermittent faults inside module | Cold solder joint or varnish defect | ⚠️ Medium | Inspect board under magnification | Replace with known good PCB |
| Component overheat on main board | Fault elsewhere, PCB misinterpretation | ❌ Low | Measure temperature under load | Check main board drivers and power rails first |
| No response to controller inputs | Downstream logic fault | ❌ Low | Test control logic and harness continuity | Verify field wiring before PCB swap |
| Unexplained communication glitches | Noise or poor board contact | ⚠️ Medium | Wiggle test with power off, check connectors | Retorque and ensure clean contacts |
Field note: As a subcomponent PCB, this part rarely “causes failure by itself” — errors usually originate from connector/wiring issues, main board faults, or environmental corrosion. Only remove/replace after confirming broader system diagnostics.

6. Frequently Asked Questions (FAQ)
Q1: What exactly is this board used for?
A: It’s a varnish-coated subboard PCB assembly (ABB designation KU C755 AE) used as an internal subcomponent in ABB industrial automation devices and control modules.
Q2: Is this a standalone module?
A: No — this is a printed circuit subboard intended to mount inside larger assemblies, not a standalone controller or power module.
Q3: What equipment does it fit?
A: It’s generally found inside ABB drives and automation modules where OEM internal boards require replacement; exact rack/board maps should be confirmed from equipment service manuals.
Q4: Where was it made?
A: It is supplied with origin Switzerland (CH) and often recorded as a new assembled subboard with varnish.
Q5: Why is this cheaper than direct ABB list price?
A: This item is typically offered as New Surplus or secondary inventory — not fresh from current ABB manufacturing — which brings pricing down relative to legacy OEM list. Confirm supplier testing SOP before purchase.
Q6: What should I check before installation?
A: Confirm that the revision code matches the original board’s part number, ensure correct seating and clean contacts, and verify no connector or main board damage exists before swapping subboards.
