Watertight construction with IP67 sealing reduces moisture ingress and guards against washdown fluids, lengthening service life and reducing unplanned downtime in harsh environments. This translates to fewer service interruptions, lower maintenance costs, and improved equipment availability for continuous production lines in food processing, chemical plants, and water treatment facilities. Back-wiring compatibility enables faster, mistake-free field connections, decreasing installation labor and field error rates while improving reproducibility across panels and enclosures. The three-pole, four-wire L16-20 configuration supports standard three-phase motors and drives on 480 V systems, streamlining compatibility with existing plant infrastructure and spare part inventories. Nickel-plated brass contacts and Santoprene seals deliver strong conductivity with corrosion resistance, supporting reliable performance under high vibration and temperature cycling. The nylon body and yellow color aid identification and durability, while the 14-16 lbf-in torque rating ensures robust mating and retention in demanding environments. Compliance with RoHS and cULus enhances regulatory confidence for global deployments and reduces risk in cross-border projects.

FAQs
The L1620PW is designed for industrial control panels and washdown areas, featuring back-wiring for straightforward field wiring, a three-pole four-wire L16-20 configuration, and a cord diameter range of 0.36 to 0.84 inches. It handles up to 20A at 480V, making it ideal for motors, pumps, and conveyors in harsh environments while maintaining secure, compliant connections.
IP67 protection means the connector can withstand immersion in water up to a depth of one meter for 30 minutes and resist dust ingress. In practice, this seals against moisture and cleaning solvents, reduces corrosion risk, and minimizes unexpected downtime in food processing, chemical plants, and other facilities with frequent washing or high humidity.
Yes. The L1620PW is RoHS compliant and cULus listed, ensuring reduced hazardous substance usage and safety certification for United States and Canadian markets. This supports global deployment strategies, supplier quality programs, and regulatory adherence across multinational projects without sacrificing electrical performance.
The device is built as a three-pole, four-wire locking plug rated for 480 V three-phase systems, aligned with the L16-20 NEMA configuration. This compatibility simplifies motor and drive connections, reduces voltage mismatch risks, and enables seamless integration with existing plant electrical foundations and spare-part inventories.
Maintenance benefits include minimized wiring errors due to back-wiring, reduced seal degradation from robust IP67 protection, and longer service intervals thanks to corrosion-resistant contacts and durable Santoprene sealing. ROI gains arise from lower downtime, faster commissioning, lower maintenance labor, and safer, compliant operation across high-demand motor and conveyor applications.
