Large Distribution Box Model and Specifications

Large distribution boxes range from low-voltage switchgear to high-capacity power distribution cabinets, with models supporting 220V–1000kVA and various mounting and material options.

Low-Voltage Fixed and Withdrawable Switchgear

• GGD Series: Fixed low-voltage switchgear, AC 50Hz, rated voltage 380V, high breaking capacity, stable performance, commonly used in substations and power plants .
• GDH Series: Similar to GGD, with manufacturer-specific variations for industrial power distribution .
• PGL Series: Low-voltage fixed switchgear for stable power supply in industrial and commercial applications .
• GCK Series: Withdrawable low-voltage switchgear, AC 60Hz, rated voltage 660V, suitable for motor control centers and lighting systems .
• GCS Series: AC 50Hz, rated voltage 400V, used in power plants, high-rise buildings, and heavy-load environments .
• MNS Series: Compact, stable low-voltage distribution system for small power plants, industrial enterprises, and hotels .

High-Capacity Power Distribution Cabinets

• Vertiv™ Liebert® PPC: Designed for high-density applications such as AI workloads, with capacities from 400 kVA to 1000 kVA. Features include custom sub-feed breaker configurations, raised floor or top-exit models, and flexible expansion for growing sites. Warranty is 18 months for parts .

Plastic and Modular Distribution Boxes

• JUNON C6 Series: Flush or surface-mounted, AC 50Hz, rated voltage 220V/380V, made of flame-proof PC material. Suitable for residential, commercial, and industrial applications. Includes modular combination equipment, overcurrent, overload, and short-circuit protection .
• Specifications: Typically include cover, frame, base box, guide rail, neutral and earth copper bars. Available in single-phase or three-phase configurations, with surface or flush mounting options .

Key Considerations

• Voltage and Frequency: Choose based on application (220V–400V for residential/commercial, 380V–660V for industrial, up to 1000kVA for high-density data centers), .
• Mounting Type: Flush-mounted for wall integration, surface-mounted for easy access .
• Material: Flame-proof PC plastic for safety in residential/commercial units; metal enclosures for industrial and high-capacity systems .
• Capacity and Expansion: High-capacity cabinets like Liebert PPC allow flexible expansion and custom breaker configurations . These models cover a wide range of applications from residential and commercial power distribution to industrial and mission-critical high-density environments, providing options for both modular plastic boxes and high-capacity switchgear systems.
