Comparison with Marechal PNC/PNCX
| Feature | KEX PNCX (Korea) | Marechal PNCX (France) |
|---|---|---|
| Voltage / Current | 250V / 5A | Up to 480V / 16A |
| Material | GRP | Polyamide / Metal options |
| Certification | KCs, Ex eb IIC | ATEX, IECEx |
| Ingress Protection | IP66/IP67 | IP66/IP67/IP69 |
| Best Use Case | Compact, light-duty hazardous area connections | Heavy-duty industrial hazardous environments |
� Key Considerations
- Choose KEX PNCX if you need a lightweight, compact connector for Zone 1/2/21/22 applications with moderate current (≤5A).
- Choose Marechal PNCX if your installation requires higher current capacity (up to 16A) or stricter ATEX/IECEx compliance.
- Always verify local certification requirements (KCs vs ATEX/IECEx) depending on installation region.
