Watertight protection and IP67/NEMA-rated construction deliver reliable operation in wet or dusty environments, reducing corrosion risk and unplanned downtime while enabling consistent performance in outdoor or washdown areas. This 30A, 480V L16-30 configuration supports three-pole, four-wire loads, making it suitable for industrial motors and power distribution feeds. Back-wiring for #18-10 AWG wires streamlines installation, minimizes termination points, and speeds commissioning in new builds or retrofits. The locking mechanism provides a secure, vibration-resistant connection that prevents accidental disconnections in high-vibration environments found in manufacturing floors. Nickel-plated brass contacts ensure durable conductivity and corrosion resistance, while Santoprene elastomeric seals extend service life in harsh conditions. The nylon body keeps the assembly lightweight yet robust, ideal for field service and maintenance crews, with a 20 lbf-inch torque rating guiding consistent tightening across crews. Compatibility with standard L16-30 mating configurations supports a wide range of Eaton and third-party accessories, reducing total cost of ownership by simplifying spare parts and training.

FAQs
Power must be disconnected before wiring. Use back-wiring terminals designed for #18-10 AWG. Strip insulation to the appropriate length, insert conductors fully, and tighten to the specified torque of 20 lbf-inch. Verify a secure seal and correct polarity before mating with the corresponding receptacle. This approach speeds field terminations while maintaining reliability.
The L1630CWBK is RoHS compliant and cULus listed, with an IP67 ingress protection rating and a NEMA L16-30 configuration. It supports 30A at 480V and provides a three-pole, four-wire setup, making it suitable for industrial motors and power distribution in harsh environments.
Yes. With IP67 protection and NEMA 4/4X/6P/6 compatibility, the connector resists water ingress and corrosion in outdoor, washdown, and harsh industrial settings. Its watertight sealing and locking mechanism help maintain reliable connections despite vibration, moisture, or dust.
The locking mechanism prevents accidental disconnects in vibration-prone applications, enhancing safety and uptime. Combined with a watertight seal, nickel-plated brass contacts, and a rugged nylon body, it delivers a durable, high-performance connection suitable for demanding industrial environments.
Regularly inspect the locking latch, seals, and contacts for wear or damage. Ensure the torque on the connection remains at about 20 lbf-in and confirm that the cord grip accommodates #18-10 AWG. Periodic cleaning and moisture checks help preserve IP67 integrity and prolong service life in challenging environments.
