FAQs
The L1120RWBK uses back wiring for up to #14-8 AWG conductors. This design simplifies field wiring, improves terminal security, and reduces installation time. Ensure conductors are cleanly stripped to the specified length and tighten screws to the manufacturer’s torque recommendations to prevent overheating and maintain a solid, code-compliant connection.
This receptacle is RoHS compliant and NOM/cULus listed, with environmental ratings including IP66 and NEMA 4X, plus NEMA 3R protection. These ratings confirm suitability for outdoor and washdown conditions, while regulatory certifications support compliance in North American and global projects, reducing risk during audits and procurement.
Yes. The L1120RWBK is a locking receptacle configured for L11-20 three-phase connections, designed to integrate with compatible Eaton locking devices and enclosures. Its back-wiring option and robust nickel-plated bronze contacts ensure reliable mating and consistent performance when paired with other Eaton components in industrial power systems.
The unit excels in harsh environments such as washdown areas, outdoor installations, and dusty or humid facilities. With IP66/NEMA 4X protection and a rugged thermoplastic/n nylon body, it resists water intrusion, corrosion, and vibration, making it ideal for manufacturing floors, food processing, and outdoor equipment enclosures.
By providing a durable, watertight connection with locking security, the receptacle reduces unplanned outages and disconnect events. The back-wiring design speeds installation, lowers labor costs, and the corrosion-resistant contacts extend service life, translating to lower maintenance spend and improved uptime for mission-critical equipment.
