Eaton Crouse-Hinds CEX133-B12-327SN Roughneck Plug - Zone 1
Part Number: CEX133-B12-327SN
Quick Summary
Eaton Crouse-Hinds CEX133-B12-327SN cable mounted plug is a rugged solution for hazardous-location power connections in demanding industrial environments. It reliably seals and terminates #12 AWG conductors with a crimped socket contact, even where exposure to dust, moisture, or chemicals is high. This assembly carries IECEx/ATEX, NEC/CEC, and Zone 1 ratings along with IP68 and IP66 protection, delivering regulatory compliance and safer operation in the field. For procurement teams and engineers, the combination of a compact shell size and a robust Eex d gland reduces part numbers and simplifies spares when stocking Roughneck connectors. In practice, you gain safer installations, faster commissioning, and sustained performance across oil, gas, and chemical processing facilities.

FAQs
The CEX133-B12-327SN accepts unarmoured conductors up to #12 AWG with crimp termination and uses an EEx d gland. It supports inner sheath sizing of 13.5–20.5 mm and outer sheath of 18.0–27.5 mm, enabling secure strain relief for field wiring and ensuring a proper seal in hazardous environments when paired with the correct mating Roughneck connector.
With a 30A amperage rating and #12 AWG silver-plated copper contacts, the plug handles standard motor control and smaller electrical loads reliably. The socket/crimp configuration reduces contact resistance and wear, delivering consistent performance over time while the EEx d gland maintains a gas-tight seal in hazardous locations.
Yes. The CEX133-B12-327SN carries IECEx/ATEX Zone 1 ratings, NEC/CEC compliance, and IP68/IP66 protection, making it suitable for hazardous-area installations in oil, gas, chemical, and mining environments where flammable atmospheres may be present.
Key certifications include IECEx/ATEX for Zone 1 hazardous areas, NEC/CEC for North American compliance, IP68/IP66 for ingress protection, and NEMA 6P 4X for rugged enclosure compatibility. These credentials help ensure regulatory acceptance, safety, and long-term reliability in demanding industrial settings.
The Roughneck CEX133 enables quick field wiring with crimp termination and a robust EEx d gland, reducing commissioning time and spare-part diversity. Its durable build and hazard-location certifications translate into lower maintenance costs and less downtime, delivering faster return on investment in continuous-operation facilities.
