MechStream now offers the essential drawing for a Standard External Control Box E (Ex e), available for immediate download. This critical CAD file provides a detailed, fabrication-ready blueprint for an “Increased Safety” enclosure. This type of box is specifically engineered for use in external, hazardous, or explosive atmospheres (like Zone 1 & 2) found in chemical plants, oil refineries, and off-shore platforms.
This is not a standard electrical box. Our free drawing details a robust housing designed to protect control stations, terminal blocks, switches, and circuit breakers from both severe environmental conditions and the risk of igniting surrounding combustible gases or dust. The “Ex e” standard ensures that the enclosure is built to prevent any possibility of sparks, arcs, or high temperatures.
This drawing is indispensable for mechanical and electrical engineers designing systems for classified hazardous locations. It saves hundreds of hours of complex design work by providing a proven, compliant framework. Download this file to accelerate your project, ensure the safety and integrity of your control components, and meet stringent international safety standards.
Key Features:
- Hazardous Area Compliant: Designed to meet “Ex e” (Increased Safety) standards for use in potentially explosive atmospheres.
- Robust Materials: Models a heavy-duty enclosure from corrosion-resistant materials, typically Stainless Steel (316L) or GRP (Glass-Reinforced Polyester).
- High IP Rating: Features a high-integrity gasket system (e.g., silicone) and secure fasteners to achieve an IP65/IP66 rating, ensuring total protection from dust and high-pressure water.
- Component Ready: Includes internal mounting provisions for DIN rails, mounting plates, and earth continuity plates.
- Multi-Format File: Provided in versatile DWG and STEP formats, compatible with AutoCAD, SolidWorks, and other major CAD platforms.
