Product Features

1. Modular Structure
    

   The main cabinet, busbar, distribution unit, and protection unit all adopt standardized modules, enabling quick assembly, disassembly, and upgrade.

2. High Reliability
    

   Copper busbars, high-temperature resistant insulating materials, and arc-proof technology are employed to ensure reliable disconnection under high short-circuit current conditions.

3. Flexible Configuration
    

   A variety of protection, monitoring, and communication modules (e.g., MLT-SCADA, Modbus-TCP) can be optionally configured to meet the requirements of intelligent power distribution.

4. Compact Size
    

   Compared with traditional distribution cabinets of the same rated current, its volume is reduced by 15%-30%, facilitating on-site installation in space-constrained environments.

5. User-Friendly Operation
    

   Equipped with LED status indicators, a detachable operation panel, and ergonomic handles to reduce maintenance difficulty.

Structure and Components

• Main Cabinet Body: Steel or aluminum alloy enclosure, providing mechanical protection and grounding.
• Busbar System: Copper or aluminum busbars connected by crimping or bolting to ensure low impedance and high heat dissipation.
• Distribution Unit: Comprising circuit breakers, contactors, fuses, relay protection devices, etc., which can be freely combined according to circuit requirements.
• Control and Monitoring Modules: PLC, remote I/O, communication gateways, display panels, etc., enabling local or remote monitoring.
• Accessories: Lightning protection modules, overvoltage protection devices, temperature sensors, grounding bars, junction boxes, etc.

Typical Application Fields

• Industrial Power Distribution: Main distribution cabinets for large production lines, automated workshops, and robotic systems.
• Building Equipment Rooms: Power distribution and protection for data centers, communication base stations, and building automation systems.
• Energy Stations: DC/AC power distribution for photovoltaic inverter stations, wind power converter stations, and energy storage systems.
• Commercial Facilities: Centralized power distribution and backup power management for large shopping malls, hotels, and hospitals.

Installation Guidelines

1. On-Site Inspection: Verify that the ventilation, temperature, humidity, and dust-proof rating of the equipment room or power distribution room meet the requirements of IP20/IP54.
2. Foundation Fixation: Securely install the cabinet using bolts or a base, ensuring horizontal and vertical alignment to prevent mechanical vibration during operation.
3. Grounding: The main cabinet body, busbars, and metal accessories must be reliably grounded, with a grounding resistance ≤ 1 Ω.
4. Busbar Connection: When adopting crimping or bolting connections, ensure clean contact surfaces and that the tightening torque complies with the requirements specified in technical documents.
5. Circuit Wiring: Follow the IEC 60947-1/2 standards, keep phase lines, neutral lines, and protective lines separated, and avoid cross-connection and excessively long branch circuits.
