Watertight IP67 design with a Santoprene seal provides reliable protection in wet or dusty environments. This combination reduces moisture ingress and equipment downtime, extending service life and improving reliability in the field. Three-pole, four-wire NEMA L18-20 configuration supports 20A at 120/208V. Engineering impacts: this configuration supports three-phase motors and safe grounding, reducing miswiring risk. In practice, it enables plug-and-lock connections that simplify motor control center wiring and commissioning. Back wiring for #18-10 AWG simplifies field terminations. It delivers faster install, tighter terminations, and improved pull-out resistance. Nickel-plated brass contacts deliver low resistance and durable performance under vibration. Torque rating of 14-16 lbf-in ensures reliable seating and consistent torque across installations. Nylon body with black finish and Santoprene material provides chemical resistance and physical durability. RoHS compliant and cULus listed ensure regulatory alignment across global operations. Compatibility with Eaton locking devices and existing L18-20 assemblies simplifies upgrades. Industry insights: using locking plugs reduces unplugging incidents and improves safety in harsh environments.

FAQs
The L1820PWBK accepts #18-10 AWG conductors with back wiring. Strip insulation per manufacturer guidance, insert conductors into the back-wired terminals, and tighten to the specified torque of 14-16 lbf-in. Verify nickel-plated brass contacts are seated and conduct a gentle pull test to confirm secure terminations. This approach reduces field wiring errors and speeds up panel assembly while maintaining a robust, moisture-protected connection.
Yes. The L1820PWBK is a three-pole, four-wire locking plug configured for L18-20 and rated at 20A with a voltage of 120/208V. Its IP67 protection and rugged construction support reliable operation in demanding industrial environments, making it suitable for motors, pumps, and control circuits that require a secure, three-phase connection.
Absolutely. With IP67 ingress protection and a Santoprene seal, the L1820PWBK is designed for wet, dusty, or wash-down environments. The nylon body provides additional durability, while the locking mechanism minimizes accidental disconnections during operation, supporting continuous production and safer equipment interfaces.
This locking plug is RoHS compliant and cULus Listed, signaling regulatory compliance for modern electrical installations. Its IP67 rating further confirms suitability for harsh environments, ensuring reliable performance in industrial facilities that demand both safety and environmental protection.
Expect reduced maintenance intervals and fewer field wiring mistakes due to back-wiring and a robust locking mechanism. The IP67 protection minimizes moisture-related faults, and nickel-plated brass contacts maintain low resistance over time, contributing to longer service life, fewer unscheduled downtime events, and a lower total cost of ownership for equipment relying on secure, durable connections.
