FAQs
Yes. The CEX133-C216-312SN is designed for unarmoured cables with a #12 AWG conductors and an EEx d gland, making it suitable for Zone 1 hazardous locations. Follow the manufacturer’s installation sheet to ensure proper gland sealing, mounting orientation, and crimp termination for safe operation.
The connector carries IECEx/ATEX Zone 1 certification and IP66/IP68 ingress protection, plus NEMA 4X 6P enclosure ratings. These certifications ensure safe operation in hazardous environments with washdowns, dust, and moisture exposure, meeting common refinery and chemical-plant standards.
Key specs include a 30A amperage rating, #12 AWG contact size, socket contact type, and crimp termination. These attributes enable reliable power delivery to motors and pumps while maintaining low contact resistance, reducing heat buildup and downtime in continuous-operation equipment.
The EEx d gland provides robust enclosure integrity and safe sealing for hazardous locations, simplifying field assembly and reducing the risk of gas or dust ingress. This design is particularly beneficial during retrofit projects where existing cable runs need secure, gas-tight termination.
Benefits include reduced maintenance and downtime, improved safety compliance, and longer service life due to robust materials (silver-plated copper contacts and corrosion resistance). Although ROI varies by application, faster terminations and lower failure rates typically translate to lower operating costs over the equipment lifecycle.
