FAQs
The L1920PWBK is designed for back wiring with #18-10 AWG conductors and supports a 277/480V three-phase load. It features a four-pole, four-wire L19-20 configuration, enabling secure, code-compliant terminations in industrial panels and machinery. This combination simplifies field wiring while maintaining robust electrical performance in demanding environments.
This locking plug is RoHS compliant and cULus listed, ensuring compliance with global safety and environmental standards. It also carries an IP67 rating for water and dust ingress protection, making it suitable for harsh industrial settings such as washdown zones and outdoor installations.
Yes. With IP67 protection and a watertight seal, the plug resists moisture and dust ingress even in challenging environments. The rugged nylon body and nickel-plated brass contacts are designed to withstand corrosive outdoor or washdown conditions, helping to maintain low failure rates and stable operation.
Plan for back wiring with #18-10 AWG conductors and ensure proper secure termination in the four-pole L19-20 configuration. Maintain compatibility with 277/480V three-phase systems and confirm enclosure ratings align with IP67 requirements. The unit’s locking mechanism aids vibration resistance, which is advantageous in dynamic industrial environments.
The watertight seal and corrosion-resistant contacts minimize contact degradation, reducing maintenance intervals and downtime. RoHS and cULus compliance streamline procurement and regulatory alignment, while the IP67 rating and rugged construction extend service life in harsh environments, delivering a lower total cost of ownership for critical automation infrastructure.
