MNS Tie Cabinet

The MNS Tie Cabinet is a high-safety interconnection unit within the MNS distribution system, acting as the final safeguard for critical load power supply. Positioned between two main bus sections, it manages redundant power sources and handles high-current switching. This cabinet ensures reliable load transfer without arc propagation, providing robust physical protection for high-end low-voltage distribution systems.

The MNS Tie Cabinet features a dual protection mechanism, combining PLC-based logical interlocking with mechanical interlocking to eliminate the risk of unintended parallel connection of power sources. Its compartmentalized structure confines any arc faults to a single section, while the design resists vibration and electromagnetic interference. With exceptional short-circuit withstand capability, it is suitable for large transformer systems and other high-fault-current environments, ensuring precise and reliable switching operations.

Standard: IEC 60947-2
Rated Short-Time Withstand Current (Icw): 100kA/1s
Peak Current: 220kA
Interlocking Mode: Mechanical + PLC logical interlocking

The cabinet is constructed with a C-profile frame and high-strength bolted connections, avoiding welding stress and fatigue issues. Busbars utilize fully enclosed plug-in connections or silver-plated flexible links for stable performance under high currents. Power and control circuits are arranged with layered wiring and EMC considerations to ensure accurate operation. Customized solutions, on-site commissioning, and full technical support are provided for every MNS Tie Cabinet, guaranteeing safe and reliable performance.
