Description
Technical Advantages
1. Robust and Reliable Electrical Performance
Utilizing a standardized top-mounted horizontal busbar system, the unit supports both 3-pole and 4-pole configurations. With a system rated current reaching up to 7400A and a rated peak withstand current (Ipk) of up to 375kA, it is capable of effortlessly handling high-current surges and short-circuit faults across a wide range of complex operating conditions.
2. Ample Space and High Compatibility
The device compartments feature generous depth dimensions, perfectly accommodating the installation requirements of various mainstream low-voltage components. This design reserves ample space for future system upgrades and functional expansions, significantly enhancing project configuration flexibility.
3. Rigorous Quality Control Throughout the Entire Process
Prior to shipment, every unit undergoes a comprehensive series of type tests. By integrating industry-leading switching and automation technologies with high-quality core components—and enforcing strict quality checks at every stage from design and production to final inspection—we ensure the long-term safety and stability of the equipment.
4. Flexible and Versatile Installation Options
The system supports two installation modes: single-sided wall-mounted and back-to-back double-sided configurations. Featuring a compact cabinet structure, the unit allows for flexible layout planning based on on-site spatial conditions, thereby effectively maximizing space utilization within the power distribution room and reducing civil engineering and installation costs.
5. Adaptability to All Application Scenarios
Offering a rich variety of system configurations and cabinet solutions, the unit is widely applicable across diverse low-voltage power distribution scenarios—including commercial buildings, industrial facilities, data centers, and infrastructure projects—effectively meeting the unique and personalized requirements of various industries and projects.
