Nationwide Non-standard Explosion-proof Distribution Box Power Supply

Explosion-proof distribution boxes provide safe, reliable power distribution in hazardous environments, with options for non-standard, customized configurations certified to ATEX and IECEx standards.

Overview

Explosion-proof distribution boxes are low-voltage power distribution devices designed to safely manage electrical circuits in hazardous areas where flammable gases, vapors, or dust may be present . They integrate switchgear, protective devices, measuring instruments, and auxiliary equipment within a sealed or semi-sealed metal enclosure, preventing sparks or heat from igniting explosive atmospheres . These boxes are widely used in petroleum, chemical, mining, and industrial sectors.

Key Features

• Explosion Protection Types: Options include Ex d (flameproof), Ex e (increased safety), Ex i (intrinsically safe), and Ex p (pressurized housing), with combinations available for specific applications .
• Certifications: Many units are ATEX II 2GD and IECEx certified, suitable for Zone 1 and Zone 2 hazardous areas .
• Power Handling: Capable of handling low-voltage distribution from 60A to 250A, with configurations for lighting, motors, valves, pumps, and heat tracing circuits .
• Customization: Non-standard or customer-specific designs allow integration of control and signaling devices, modular components, and specialized switchgear .
• Safety Features: Include manual or automatic switching, circuit protection, alarms, and real-time monitoring of electrical parameters to prevent accidents .

Applications

Explosion-proof distribution boxes are essential in environments where electrical sparks could trigger explosions, such as:

• Oil and gas facilities
• Chemical plants
