Switchgear & Distribution
Three-Level Construction Site Distribution Box
Built for temporary power distribution on construction sites, this IP65-rated floor-standing distribution box organizes 16 circuits across a 3-level switch architecture, with color-coded industrial round sockets for direct tool and equipment connection. A weatherproof rain-hood roof and support legs suit outdoor site conditions, while circuit count, socket configuration, and enclosure size are engineered to your project as a B2B, OEM/ODM-ready platform.





Key Features
Built as a B2B platform product for contractors, rental fleets, and project developers who need site distribution boxes configured to their own standard.
IP65 Weatherproof Protection
A sloped rain-hood roof and sealed enclosure protect internal switchgear from rain, dust, and outdoor site exposure.
Three-Level Distribution Architecture
16 circuits organized across 3 switch levels support staged site power distribution and clearer circuit management.
Industrial Round Socket Outlets
Color-coded three-phase and single-phase industrial sockets provide direct, secure connections for tools and equipment.
250A Rated Current
Rated for 250A with a 50kA short-circuit making current rating for reliable protection under fault conditions.
Reinforced Steel Enclosure
1.5mm cold-rolled steel panels with a powder-coated white finish deliver a durable, corrosion-resistant enclosure.
OEM/ODM Ready
Custom circuit count, socket configuration, and labeling available for B2B and project-specific orders.
OEM & ODM Capabilities
Flexible OEM and ODM support covering product configuration, specifications, labeling, branding, packaging and project-specific customization requirements.
Custom Circuit & Socket Layout
Number of outgoing circuits, switch levels, and socket types configured to your site distribution plan.
Custom Enclosure Dimensions
Reference size is 1000×800×200mm — scalable for higher circuit counts or more compact site requirements.
Floor-Standing or Wall-Mounted
Available with support legs for floor-standing installation, or without legs for wall/pole mounting.
Socket Type & Rating Options
Industrial round sockets available in various current ratings and pin configurations to match your regional plug standard.
Finish & Branding Options
Standard white powder-coat finish; private-label nameplates and RAL color matching available for B2B partners.
Factory-Direct OEM/ODM Production

Construction & Configuration
Every element is arranged for reliable outdoor operation and clear staged circuit protection.
Weatherproof Rain-Hood Roof
A sloped top cover sheds rain and debris away from the door seal and ventilation points.
Floor-Standing Support Legs
Reinforced steel legs elevate the enclosure off the ground for stable outdoor site installation.
Industrial Round Socket Outlets
Color-coded circular connector sockets (red for three-phase, blue for single-phase) mounted on the side panel for quick equipment hookup.
Locking Door with Warning Label
A key-locked door with an electrical hazard warning label restricts access to qualified personnel.
Three-Level Switch Arrangement
Incoming main switch, intermediate distribution switches, and final outgoing circuit breakers are organized across three protection levels.
Rating & Certification Nameplate
A nameplate on the door records key ratings and certification details for site inspection and compliance records.
Standards & Test Documentation
Manufacturing and enclosure performance are backed by recognized certification and IP protection standards, with full OEM/ODM documentation support.
CQC Certified Manufacturing
Produced under CQC certification, giving your project a verified quality and safety baseline for electrical enclosure manufacturing.
IP65 Ingress Protection
Rated to IP65 under IEC 60529, providing full protection against dust ingress and low-pressure water jets from any direction — suitable for outdoor construction site installation.
Build-to-Schedule OEM/ODM Production
Circuit count, switch levels, and socket configuration are engineered to your site distribution plan, with OEM/ODM documentation support for contractors and B2B partners.
