Explosion-proof plug devices for distribution boxes are available in certified models such as R.

STAH

L plugs, ATEX/IECEx-compliant sockets, and CZ1290 modular distribution boxes suitable for hazardous zones. Key Models and ManufacturersR.

STAH

L Plugs and Sockets: These explosion-protected plugs and connectors are designed for safe electrical energy distribution in hazardous areas. They feature integrated load disconnect switches, full motor switching capacity, and locking mechanisms for added safety. They are suitable for worldwide use and certified for Zone 1 and Zone 2 explosive atmospheres.

CZ1290 Explosion-Proof Distribution Boxes: Manufactured by CZ Electric Co., Ltd, these modular distribution boxes are designed for petrochemical, medical, food processing, aerospace, and military applications. They feature easy operation with panel windows, internal wiring completed, and external wiring only required for connection. The CZ1290 series is widely exported and used in major international projects.

Feice Explosion-

Proof Distribution Boxes: These aluminum alloy boxes are suitable for flammable gas (Zones 1 and 2) and dust environments (Zones 21 and 22). They support temperature groups T1–T6 and include modular cavities, high-density die-cast aluminum construction, corrosion-resistant coatings, and secure operating mechanisms with padlock options.

Warom Explosion-

Proof Equipment: Warom offers a range of explosion-proof distribution boxes and plug devices compliant with IEC, ATEX, and IECEx standards. Their products are used in petroleum, chemical, marine, and mining industries, providing reliable safety in hazardous locations.

Features to Consider

Certification: Ensure compliance with ATEX, IECEx, or CENELEC standards for hazardous zones. Zone Compatibility: Devices are rated for Zone 1, Zone 2 (gas) and Zone 21, Zone 22 (dust) environments. Temperature Group: T1–T6 ratings indicate maximum surface temperature for safe operation.

Modular Design: Allows flexible configuration for different power distribution needs. Safety Mechanisms: Integrated load disconnect switches, locking functions, and padlock options prevent accidental disconnection. Material and Durability: Die-cast aluminum or stainless steel construction with corrosion-resistant coatings ensures long-term reliability.

ApplicationsExplosion-proof plug devices and distribution boxes are widely used in: Oil and gas extraction, refining, and petrochemical plantsOffshore platforms and oil tankersChemical and pharmaceutical industriesGrain storage, metal processing, and military facilitiesAerospace and precision electronics projects These devices ensure safe electrical distribution and control in environments with flammable gases or dust, preventing ignition and enhancing operational safety.
