The Wolf ATEX Splitter Box is a high-durability, modular ex-proof power distribution unit designed for establishing temporary lighting networks in hazardous areas. Offered by IST Safety Ltd, the official distributor of Wolf, these distribution boxes safely split power from a single source to multiple luminaires or equipment, minimizing cable clutter on-site.
Certified for Zone 1/21, the unit features a GRP (Glass Reinforced Polyester) enclosure that is highly resistant to impacts, corrosion, and harsh industrial chemicals. It provides full protection against water and dust ingress with its IP66 ingress protection rating. Fully compatible with LinkEx™ lighting systems, these splitters are available with various ATEX plug and socket options, enabling the creation of a flexible and secure electrical infrastructure in critical sites, from refineries to tank cleaning operations.
The Wolf ATEX Splitter Box is small, portable, and CE marked for safe use in Zones 1 and 2 (explosive gas) and Zones 21 and 22 (dust) atmospheres. It is perfect for power distribution in hazardous confined spaces.

What is ATEX and what does exproof mean? The ATEX directive is a set of European Union standards that define the safety requirements for equipment used in hazardous areas with explosive atmospheres. Exproof (Explosion-proof) refers to protection methods designed to prevent explosions by inhibiting the formation of sparks or electrical arcs in environments containing flammable gases, dust, or vapors. To ensure life and property safety in industrial facilities, the use of ATEX-certified exproof devices is a legal requirement.
ATEX Zone coding is a technical classification based on the frequency and duration of the occurrence of an explosive atmosphere in a given area. While the terms Zone 0, 1, and 2 are used for risks originating from gas, vapor, and mist; the codes Zone 20, 21, and 22 are designated for environments containing combustible dust. This classification is a legal standard that determines the required Equipment Protection Level (EPL) for devices. Accurate zone identification both optimizes operational costs and minimizes occupational safety risks.
In addition to ATEX certification, some projects may also require the IECEx Certification System (International Electrotechnical Commission Explosive Atmospheres System) certification. IECEx is an internationally recognized conformity assessment system for equipment intended for use in explosive atmospheres.
While ATEX is a European Union directive and a legal requirement within the European market, IECEx is a globally accepted certification system, widely preferred in regions such as the Middle East, Asia, and Australia.
From a technical perspective, both ATEX and IECEx are based on similar standards (e.g., the EN/IEC 60079 series). However:
Therefore, while ATEX certification may be sufficient for certain projects, international tenders or critical industries such as oil & gas often prefer or require products that are certified to both ATEX and IECEx standards.
The appropriate certification should be determined based on the project location, client requirements, and application area.
