FAQs
The CEX-133-C20-359PN uses an EEx d gland and is designed for unarmoured cables with inner sheath in the range 18.0–27.5 mm and outer sheath 23.0–34.0 mm. It supports #8 AWG conductors with crimp termination, enabling secure, gas-tight connections in Zone 1 hazardous locations. When selecting glands, ensure compatibility with the gland thread and enclosure ratings to maintain IP66/IP68 protection and NEMA 4X performance.
This plug is rated for 55 A and uses silver-plated copper contacts for reliable conduction. It is supplied for Zone 1 hazardous locations under IECEx/ATEX and meets IP66/IP68 protection standards with a NEMA 4X 6P configuration, making it suitable for harsh environments and washdown areas.
Yes. The product carries IECEx/ATEX certifications with Zone 1 hazardous ratings and area classification for hazardous/classified locations. It is designed to operate safely in such environments, with a robust EEx d gland and corrosion-resistant contacts to maintain performance in demanding industrial settings.
The CEX-133-C20-359PN uses crimp termination for #8 AWG conductors and a compact shell size 20, which simplifies routing and reduces field assembly time. The integrated EEx d gland minimizes gland-to-cable transitions, and the unarmoured cable compatibility lowers preparatory work. Overall, expect shorter commissioning times and fewer sealing issues in Zone 1 installations.
By combining robust IP66/IP68 protection, Zone 1 certification, durable silver-plated contacts, and a reliable crimp-based termination, the connector reduces downtime, maintenance costs, and risk of ignition. The compatibility with standard #8 AWG conductors and unarmoured cables helps lower spare-part inventory, while IECEx/ATEX compliance supports global operations and safer, compliant plant performance.
