- Brand: TPC
- Part Type: High-voltage power capacitor
- Capacitance: 4 µF
- Voltage Rating: 2800 VDC
- Application: ABB power-electronics / drive systems
- Cross-reference: Associated in aftermarket references with ABB HL000986P0006
Technical Introduction
The TPC FPX86-9345-B is a high-voltage capacitor used in power-electronics applications where DC-link energy storage and filtering are required.
Industrial spare-parts references associate FPX86-9345-B with the ABB HL000986P0006 capacitor, which is identified as a 4 µF, 2800 VDC, 70 A component. Because secondary-market cross-references are not a substitute for an OEM interchange statement, the physical label, electrical rating, dimensions, terminal arrangement, and equipment documentation should be checked before approving this capacitor as a direct replacement.;
Best Suited For
- ABB legacy drive and converter maintenance
- Replacement of failed high-voltage DC-link components
- Strategic spare inventory for plant shutdowns

*The electrical values and ABB cross-reference are reported in secondary industrial references for the associated HL000986P0006 part. Verify the TPC nameplate and OEM documentation before treating them as definitive specifications for the individual FPX86-9345-B unit.;
Please refer to the OEM datasheet for complete capacitance tolerance, ripple-current capability, ESR, insulation, temperature range, dimensions, discharge requirements, and mounting details.
Field Engineer’s Tech Notes
- Do not use capacitance alone for substitution. A 4 µF capacitor is not automatically interchangeable with another 4 µF unit. For a high-voltage DC-link application, verify the 2800 VDC rating, ripple/current capability, terminal arrangement, physical fit, insulation, and cooling conditions.
- Investigate the reason for the original capacitor failure. In a drive or converter, premature capacitor failure can indicate excessive ripple current, elevated cabinet temperature, DC-bus overvoltage, poor connections, or other upstream faults. Installing the replacement without checking those conditions can shorten service life.
Adaptive QA & Testing Protocol
For TPC FPX86-9345-B, incoming QA begins with nameplate verification and physical inspection. The capacitor body, terminals, mounting surfaces, insulation, seals, and identification markings are checked for impact damage, corrosion, swelling, leakage, or overheating evidence.
Where the available test equipment supports the component rating, electrical testing can include capacitance measurement, insulation verification, and inspection for abnormal leakage characteristics. Test limits are applied according to the applicable OEM specification rather than generic low-voltage capacitor criteria.
For units cross-referenced to ABB HL000986P0006, the supplier record is also checked against the requested ABB spare number before shipment.
Test reports, inspection photographs, and available test videos can be provided upon request.
Buyer’s FAQ
Is TPC a direct replacement for ABB HL000986P0006?
Secondary industrial references associate with ABB . Treat this as a cross-reference rather than automatic interchange approval; verify the physical and electrical specifications against your installed capacitor and equipment documentation.
What are the electrical specifications?
The associated ABB component is published as 4 µF, 2800 VDC, 70 A. These values should be confirmed against the actual TPC unit’s nameplate and technical documentation before installation.
Is this capacitor available new or refurbished?
Condition depends on the available inventory. New surplus, new old stock, and refurbished stock may be offered. Confirm the actual condition, manufacturing information, and electrical test status before purchase.
Can you provide a test report before shipment?
Where suitable test equipment is available, inspection and electrical test documentation can be supplied before shipment. The exact testing scope depends on the capacitor’s rated voltage and the available test setup.
