Core Advantages
- Cost-Effective & Standardized: Utilizes standard modules and uniform interface design for high serialization. Effectively controls project costs while maintaining quality, ideal for medium-sized distribution projects.
- Powerful Breaking Capacity: Optimized busbar layout and insulation support ensure excellent dynamic and thermal stability. Capable of withstanding severe short-circuit current impacts.
- Flexible Configuration: Standardized functional compartments allow flexible configuration for incoming, feeder, bus tie, motor control, and capacitor compensation applications.
- Fast Installation & Easy Maintenance: Front operation and front maintenance design with ample wiring space. IP-rated enclosure resists dust/moisture, significantly reducing on-site installation and future maintenance time.
