When taking on a small factory project, the choice of distribution equipment directly affects project cost, timeline, and long-term operation.
Choose too high, and you blow the budget. Choose too low, and you face constant failures and headaches down the line.
This guide provides a practical equipment selection reference for small factory projects up to 200kW – technically sound, cost可控, and easy to install.
A complete small factory distribution system typically consists of three levels:
Level | Equipment | Function |
|---|---|---|
Incoming | Main circuit breaker | Overall plant protection, clears fault currents |
Distribution | Branch circuit breakers (MCCBs) | Independent control per circuit |
Compensation | Power factor correction panel (optional) | Improves power factor, reduces electricity costs |
Option | Configuration | Best For | Cost |
|---|---|---|---|
Economy | Incoming switch-disconnector + branch MCCBs | Very tight budget, non-critical projects | Lowest |
Standard | Incoming ACB or high-current MCCB + branch MCCBs + enclosure | Most small factories | Medium |
Complete | Standard + power factor correction panel | Motor-heavy projects, electricity cost-sensitive | Slightly higher, fast payback |
Economy Option
Incoming: Switch-disconnector (no fault protection)
Branch: MCCBs (with protection)
Risk: No protection at the incoming level – a fault can affect the entire plant
Only recommend when the client explicitly accepts the risk
Standard Option (Recommended)
Incoming: ACB or high-current MCCB
Branch: MCCBs
Enclosure: GGD or GCK panel
Safe, reliable, meets standards, good value
Suitable for most projects
Complete Option
Standard option + power factor correction panel
Improves power factor to 0.9 or above – avoids utility penalties
Recommended for projects with high motor content (pumps, fans, compressors, crushers, etc.)
Investment typically recovered through electricity savings within 6–12 months
Equipment | Recommended Choice | Notes |
|---|---|---|
Main incoming breaker | Prefer ACB; high-current MCCB acceptable if current <800A | Breaking capacity must meet system short-circuit current |
Branch breakers | Mainstream brand MCCBs | IEC type test reports required |
Enclosure | GGD (fixed) or GCK (drawout) | IP30 for indoor; IP54 for dusty/wet conditions |
Busbars | Full copper | Aluminum not recommended for cost savings |
Power factor correction panel | Size at about 30% of transformer capacity | Essential for motor-heavy projects |
Option | Main Configuration | Estimated Cost (USD) |
|---|---|---|
Economy | Switch-disconnector + branch MCCBs | 800–1,200 |
Standard | ACB + 6–8 MCCBs + GGD enclosure | 2,000–3,000 |
Complete | Standard + correction panel | 3,000–4,500 |
Note: Actual prices vary depending on component brands, quantity, and delivery terms.
