HJ-LVS-E Series Economic Withdrawable Switchgear
Up to 4000A / 65kA / Cost-Effective MCC
The HJ-LVS-E Series Economic Withdrawable Switchgear is an advanced, cost-effective low-voltage power distribution and Motor Control Center (MCC). Built with a highly flexible assembled frame and standardized withdrawable units, it delivers excellent breaking capacity, dynamic stability, and structural reliability, making it the smartest investment for general industrial infrastructure.
Ideal for Budget-Conscious General Industries:
- ✓ General Manufacturing & Assembly Plants
- ✓ Commercial Complexes & Public Infrastructure
- ✓ Water Treatment & Pumping Stations
- ✓ Light Industrial & Material Handling Facilities
1. Economical & Highly Flexible Architecture
Designed to optimize your project CAPEX without compromising performance. The cabinet frame is assembled using standardized FA components, offering infinite structural flexibility. This modular approach significantly reduces manufacturing and assembly costs while maintaining robust mechanical strength.
2. Reliable Breaking & Thermal Capacity
Despite its cost-effective positioning, the HJ-LVS-E delivers uncompromising power capabilities. The optimized busbar arrangement handles main busbar currents up to 4000A and short-time withstand currents up to 65kA, ensuring stable distribution under demanding load conditions.
3. Safe & Intuitive Withdrawable Operation
Experience the benefits of hot-swappable maintenance on a budget. The functional drawer units feature a reliable mechanical interlocking mechanism. This foolproof design ensures modules can only be moved or withdrawn when safely de-energized, protecting both personnel and the equipment.
4. High Compatibility & Easy Maintenance
The switchgear boasts a highly standardized component design, making spare parts sourcing and future capacity expansions incredibly easy and cost-efficient. The distinct compartmentalization of busbars, functional units, and cables ensures faults remain localized.
Global Factory Acceptance & Turnkey Support
Every HJ-LVS-E unit undergoes rigorous routine testing aligned with strict IEC 61439 standards before dispatch. We proudly support Remote Video FAT (Factory Acceptance Test) for our global EPC clients, ensuring total transparency.
To support local manufacturing and joint ventures, this series is fully available in CBU (Completely Built Unit), SKD (Semi-Knocked Down), or CKD (Completely Knocked Down) delivery formats.
