Power Factor Correction Capacitor Bank Panel Selection
Engineering Intent
Power factor correction panels should be sized according to load profile, harmonic condition and switching step strategy.
This article is written for engineers, EPC buyers and procurement teams who need to turn capacitor bank panel selection into a clear technical request instead of a vague product inquiry.
Key Selection Data
| Item | Data to Confirm |
|---|---|
| Check 1 | Target power factor |
| Check 2 | Reactive power kvar |
| Check 3 | Harmonic level |
| Check 4 | Contactor or thyristor switching |
Standards and Evidence to Request
- IEC 61439 panel assembly
- Capacitor and reactor datasheets
- Power quality measurement
For project approval, request a technical datasheet, outline drawing, wiring or terminal diagram where applicable, routine test report and nameplate information before shipment.
Common Specification Mistakes
- No harmonic check
- Oversized capacitor steps
- No detuned reactor where harmonics are present
RFQ Checklist
- Provide load data
- State target power factor
- Share harmonic measurement if available
- Confirm step control method

GCS, MNS and GGD panels serve different installation and maintenance requirements, so the model should match project operation needs.
ACB vs MCCB Selection for LV Panels
ACBs are common for high-current incoming feeders while MCCBs are common for outgoing distribution feeders. ZY POWER low-voltage documentation maps this selection to ZYW1 intelligent ACB and ZYM1 / ZYM1E / ZYM1L MCCB families.
