III. Core Differences: DELIXI vs. CHINT Power Distribution Cabinets
| Comparison Item | DELIXI Power Distribution Cabinets | CHINT Power Distribution Cabinets | Selection Suggestions |
| Technical Origin | Joint venture with Schneider Electric, absorbing international technologies | Independent R&ดี, guided by domestic standards | Choose DELIXI for international technical standards; choose CHINT for local project adaptation |
| Price Positioning | Mid-to-high range, 5-10% higher than CHINT | High cost performance, 5-10% lower than DELIXI | Choose CHINT for limited budget; choose DELIXI for better brand and technology |
| ขนาดการติดตั้ง | GGD/MNS series basically consistent with CHINT | NM1 series dimensionally compatible with DELIXI CDM3 series | GGD/MNS/XL-21 installation dimensions are universal for cross-brand replacement |
| Intelligence Level | New Era series with more abundant intelligent interfaces | NXM series with intelligent functions better adapted to domestic systems | Prioritize DELIXI New Era series for intelligent power distribution projects |
| Accessory Compatibility | Partially compatible with Schneider accessories | Independent accessory system with strong compatibility | Use same-brand accessories for replacement to avoid interface mismatch |
- Cross-Brand Replacement Guide (For CHINT NM1-800H/3300-800A)
- Corresponding DELIXI Components
Molded case circuit breaker: CDM3-800H/3300-800A (fully matched: 3-เสา, 800ก, H-grade breaking capacity 50kA, thermomagnetic release)
Installation dimensions: 243มม (ว) × 270mm (ดี) × 448mm (H) (completely consistent with CHINT NM1 series)
Replacement advantages: เกี่ยวกับ 5% lower price than CHINT, tripping curve closer to international standards, and technical homology with Schneider Electric
- Key Points for Overall Replacement of Power Distribution Cabinets
| Replacement Link | หมายเหตุ | Operation Suggestions |
| Component Matching | • Rated current, pole number and breaking capacity must be consistent | Make a parameter comparison table, check item by item, and focus on verifying breaking capacity and tripping curve |
| • Release type must be thermomagnetic combined release for both | ||
| • Installation dimensions must be compatible | ||
| Cabinet Structure | • GGD/MNS/XL-21 cabinet dimensions are universal | Measure the mounting hole spacing of the original cabinet to ensure the center distance of the new cabinet’s mounting holes is 200mm (adaptable to M10 bolts) |
| • Busbar specification must match (≥240mm² copper busbar) | ||
| • Mounting hole positions must be aligned | ||
| Accessory Adaptation | • Interfaces of auxiliary contacts and shunt releases may differ | Replace with same-brand accessories or use adapters to ensure normal control functions |
| • Control circuit voltage must be consistent (AC220V/380V) | ||
| • Definitions of instrument wiring terminals may vary | ||
| Commissioning and Verification | • Set the long-delay current of the release to 800A | Use a relay protection tester to simulate overload and short-circuit faults and verify the reliability of protection functions |
| • Adjust the instantaneous multiple to 10-12 ครั้ง | ||
| • Power on to test closing/opening actions |
- Core Points for Selection and Installation
- Three-Step Selection Method
- Determine load type: Power load (select breaking capacity ≥50kA), lighting load (select breaking capacity ≥35kA), mixed load (comprehensive consideration)
- Calculate rated current: Total current = ∑(equipment power × demand factor)/√3/0.38/0.85; the rated current of the circuit breaker ≥ 1.2 times the total current
- Select cabinet type: Fixed type (low cost), draw-out type (easy maintenance), waterproof type (outdoor scenarios)
- Key Installation Parameters
Mounting plate thickness: ≥5mm (adaptable to M10 bolts to ensure firm installation)
Arc flash distance: ≥100mm (avoid potential safety hazards caused by short-circuit electric arcs)
Tightening torque: 28N·m for M12 bolts of main wiring terminals to ensure reliable wiring
Copper busbar adaptation: ≥240mm² copper busbar is recommended for 800A current to meet the requirements of current-carrying capacity and heat dissipation
- Summary and Suggestions
Relying on advantages such as Sino-French joint venture technical background, high cost performance and modular design, DELIXI power distribution cabinets occupy an important position in the domestic market. Compared with CHINT, DELIXI products are slightly superior in intelligence level and international standard compatibility, while CHINT has more advantages in price and local adaptability.
Selection Suggestions:
- Industrial projects: Prioritize GGD/MNS series with supporting CDM3 series molded case circuit breakers, ensuring breaking capacity ≥50kA
- Commercial buildings: Recommend New Era/MNS draw-out cabinets with hot-swappable function for easy maintenance
- Civil projects: Select CDEN6/CDPZ50 series terminal distribution boxes for both aesthetics and practicality
- Cross-brand replacement: DELIXI CDM3-800H/3300-800A can directly replace CHINT NM1-800H/3300-800A with completely consistent installation dimensions and core parameters.
