FAQs
The 9337N employs a back-wire wiring method and supports conductors sized from #12 to #4 AWG. This enables secure, time‑efficient terminations, reduces the risk of conductor loosening under vibration, and helps maintain consistent contact pressure for stable current delivery up to 30A.
Yes. The 9337N is a three‑pole, three‑wire, non‑grounding receptacle configured for NEMA 10-30P usage. It operates at 125/250V and 30A, making it appropriate for industrial range and dryer circuits where a non‑grounding, straight blade plug is specified.
The 9337N is cULus Listed, indicating conformity with underwriter safety standards for both the United States and Canada. This certification provides assurance for compliance in regulated environments, supporting procurement approvals and quality assurance processes.
The auto grip feature ensures consistent contact seating and reduces loosening from mechanical vibration. Combined with brass contacts for durability and a robust nylon/thermoplastic body, this design minimizes downtime, extends service life, and improves electrical reliability in harsh industrial settings.
Plan for secure back-wire terminations with torques in the 20–24 lbf-in range to maintain contact integrity. Use compatible conductors (#12‑#4 AWG), ensure proper strain relief, and consider enclosure protection and ingress resistance. The unit’s materials and construction are chosen to withstand vibration, temperature cycling, and routine maintenance cycles.
