URL Slug: smc-outdoor-low-voltage-cable-distribution-box
Product Summary
This outdoor low voltage cable distribution box, model DFW, is designed for three-phase low-voltage power distribution systems. It features an SMC unsaturated polyester glass fiber composite enclosure that provides corrosion resistance and insulation for outdoor environments. With a rated operational voltage of 400V/380V and rated current of 630A, it ensures reliable power distribution to multiple circuits. Its IP54 protection degree makes it suitable for dusty and damp outdoor locations.
Key Selling Points
- Anti-Corrosion SMC Enclosure: The SMC (Sheet Molding Compound) enclosure is inherently corrosion-resistant and insulating, ideal for outdoor installations where exposure to moisture and chemicals is a concern. This prolongs the equipment's lifespan and reduces maintenance needs.
- High Rated Current Capacity: Rated at 630A with main busbar capacity from 100A to 630A, this box can handle substantial power loads, supporting multiple outgoing circuits (3 circuits: C1 180A, C2-C3 225A) for versatile distribution needs.
- Robust Protection IP54: With IP54 rating, the enclosure offers protection against dust ingress and water splashes, ensuring reliable operation in harsh outdoor conditions.
- Enhanced Safety with Short-Circuit Withstand: Rated short-time withstand current of 15kA to 20kA and peak withstand current of 40kA, providing reliable protection against short-circuit faults, minimizing downtime and damage.
- Flame-Retardant Insulation Materials: Internally, DMC insulation material with Class E heat resistance ensures flame retardancy, enhancing fire safety and operational security.

Models and Options
The DFW series is available with varying protection degrees (IP54, IP44, IP34D) and main busbar ratings from 100A to 630A. Enclosure material can be customized (SMC, 304 stainless steel, cold-rolled steel sheet). Outgoing circuit configurations can be tailored to specific project requirements, with options for different breaker ratings.
Materials and Structure
The cabinet enclosure is made of SMC unsaturated polyester glass fiber composite, offering anti-corrosion and insulation for outdoor use. Internal mounting brackets and busbar supports are galvanized or stainless steel. Conductive busbars and wiring terminals use T2 pure copper with tin plating. Insulating supports and partitions are SMC composite and epoxy insulation board. Cable entry sleeves are rubber/silicone. Cabinet locks and fasteners are 304 stainless steel. The enclosure structure is designed for outdoor installation with IP54 protection.
Applications
This low voltage cable distribution box is widely used in substations, distribution stations, industrial and mining enterprises, roadside power distribution systems, residential communities, high-rise buildings, airports, and major infrastructure projects. It distributes power from main cable lines to various users or equipment in three-phase low-voltage systems.
Customization
We offer customization for enclosure material (SMC, stainless steel, cold-rolled steel), protection degree (IP54, IP44, IP34D), and busbar current ratings (100A to 630A). Additional outgoing circuits and specific component brands can be arranged upon request. Contact us to discuss your project-specific needs.
