This is the definitive 3D drawing for a Drawer-Type Electrical Cabinet, the industry standard for safe, modular, and high-density Motor Control Centers (MCCs) and power distribution panels. This advanced design features individual, withdrawable drawers or “buckets” that house specific components like Variable Frequency Drives (VFDs), motor starters, and circuit breakers.

This modularity is the system’s greatest advantage. A 3D model is essential for engineers and panel builders to design these complex assemblies. This drawing allows you to perfectly plan the internal structure, including the main vertical and horizontal busbar systems, the guide rails for each drawer, and the complex “racking” mechanisms that allow each unit to be safely moved between “connected,” “test,” and “isolated” positions.

Used extensively in industrial plants, data centers, and manufacturing facilities, this design is critical for minimizing downtime. Instead of shutting down an entire panel for maintenance, a faulty drawer can be safely isolated, removed, and replaced in minutes. Our free drawing provides the complete blueprint for the cabinet frame and the individual drawer modules, accelerating your design and fabrication process and ensuring a reliable, safe, and easily maintainable system.

Key Features:

  • Modular Withdrawable Units: The model details the core feature: individual drawers (or “buckets”) that can be easily removed for maintenance, repair, or upgrades without powering down the main cabinet.
  • Safety Racking Mechanism: The design includes provisions for a racking system, allowing each drawer to be safely disconnected from the live busbars (moving from “service” to “test” to “isolated” positions).
  • High-Density Component Layout: This cabinet is designed to maximize space, allowing numerous motor control or feeder units to be stacked vertically in a single section.
  • Complete Busbar System: The drawing includes the critical 3-phase vertical busbar system (risers) and the main horizontal busbars, essential for power distribution to each drawer.
  • Fabrication-Ready: This is a complete 3D assembly, providing all structural sheet metal details for both the main cabinet frame and the individual drawer chassis, ready for manufacturing.
