Standard Dimensions of Explosion-Proof Distribution Boxes in Syria

Explosion-proof distribution boxes in Syria typically follow international flameproof standards (ATEX/IECEx) and are available in customizable sizes, with common enclosures made of stainless steel or aluminum alloys.

General Specifications

Explosion-proof distribution boxes used in Syria are designed for hazardous zones (Zone 1, Zone 2, Zone 21, Zone 22) and comply with Ex d IIB+H2 or Ex db IIC standards . They are suitable for applications such as feed distribution, motor control, terminal boxes, and control panels. Common materials include:

• Stainless steel (304L, 316L) for corrosion resistance and durability
• Copper-free aluminum alloy with powder coating for lightweight and mechanical strength

Typical Dimensions and Mounting

While exact dimensions can vary depending on manufacturer and user requirements, the HRMD series provides a reference:

• HRMD91/92/96 series: Modular enclosures that can be combined to save space, with customizable height, width, and depth to accommodate different numbers of terminals, breakers, and control devices
• Cable entry sizes: Standard Mx1.5 plugs, with NPT plugs available on request; the number and direction of cable entries can be customized
• Mounting: Wall-mounted or free-standing, with specialized hinge structures to protect flameproof joints during operation

Customization Options

Explosion-proof boxes in Syria are often custom-built to meet specific industrial requirements:

• Terminal arrangements and maximum number of holes on sides can be tailored to dissipated power and mechanical strength
• Support for intelligent monitoring (e.g., Modbus, RS485, RJ45, optical fiber) for remote control and data collection
• Optional equipment includes MCBs, MCCBs, AC contactors, PLCs, soft starters, meters, and indicators

Compliance and Standards

These distribution boxes are manufactured according to international standards:

• IEC 60079 series for explosive atmospheres
• ATEX 2014/34/EU and IECEx certification for hazardous area compliance
• Designed for Zones 1, 2, 21, 22 in gas and dust environments

Summary

In Syria, explosion-proof distribution boxes are modular, customizable, and built to international flameproof standards. While there is no single fixed dimension, typical enclosures are made of stainless steel or aluminum, with flexible height, width, and depth to accommodate industrial requirements. Cable entries, terminal arrangements, and mounting options are tailored to the installation site, ensuring compliance with safety regulations and operational efficiency .
