Three-Phase Box Type Power Capacitors Selection Guide: Technical Criteria & Application Standards
Three-Phase Box Type Power Capacitors selection guide: technical parameters, mounting and compliance standards, and Tibcon comparison.
A three-phase box-type power capacitor is a three-phase power factor correction capacitor whose capacitor elements are placed in a rectangular prism-shaped housing. It is used in the steps of power factor correction panels and in fixed correction per motor or machine. In this category, Tibcon models labeled 400 V, 415 V and 440 V are offered in ratings such as 0.5 kVAr, 1.5 kVAr, 5 kVAr, 10 kVAr, 12.5 kVAr and 20 kVAr; housing dimensions take values such as 123x42x145 mm and 225x77x236 mm. Choose the rating by the step plan and reactive power calculation, and the housing size by the mounting space inside the panel; verify the power obtained on 415 V and 440 V grids from the manufacturer table. Its electrical function is the same as the cylindrical type; the difference lies in the housing shape and mounting dimensions. A box-type power capacitor is not a ready-made power factor correction panel with relays and contactors inside; it is only the capacitor unit. The Three-Phase Box Type Power Capacitors category on Welibaba includes 12 active models from leading manufacturers such as Tibcon.
Key Technical Parameters for Selecting Three-Phase Box Type Power Capacitors
To specify the right Three-Phase Box Type Power Capacitors model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Power | 0.5 kVAr, 1 kVAr, 1.5 kVAr, 10 kVAr | Verify against project schedule and load calculation |
| Size Type | 123x42x145mm, 140x50x213mm, 157x54x213mm, 178x62x218mm | Verify against project schedule and load calculation |
| Voltage | 400 V AC | Verify against project schedule and load calculation |
| Impulse Current | 200 x In'ye kadar | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Power Capacitors.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Single-Phase Power Capacitors, Three-Phase Power Capacitors, Contactor Switching Modules.
