Locking receptacle
Watertight locking design delivers a secure, vibration-resistant connection in harsh facilities. The locking mechanism helps prevent accidental disengagement under heavy equipment start-up, improving uptime and safety in washdown or outdoor installations. Back wiring with #14-8 AWG conductors simplifies field terminations and reduces installation time for panels and receptacle outlets. The L2120RW uses a four-pole L21-20 configuration with five conductors including ground, ensuring a robust three-phase supply and reliable grounding for ground fault protection. Rated 20A at 120/208V and built for industrial duty, this receptacle supports common equipment loads without adapters. The device's copper/nickel-plated bronze contacts provide low contact resistance and long life, while the thermoplastic housing resists corrosion in demanding environments. Environmental protection is a standout feature with IP66 and NEMA 4X protection, enabling outdoor use and exposure to dust, washdowns, and chemical splashes. Glass-filled nylon body and thermoplastic construction balance mechanical strength and heat resistance; nickel-plated bronze contacts contribute to durability and corrosion resistance over long service life. Compliance and lifecycle value are reinforced by RoHS compliance and NOM cULus listing, backed by Eaton's industrial-grade design and test data. The combination reduces replacement cycles and support costs while maintaining regulator compliance in certified installations.
