Eaton L1930CWBK Watertight locking connector - IP67
Part Number: L1930CWBK
Quick Summary
Eaton L1930CWBK watertight locking connector provides rugged, back-wired power connections for industrial equipment in harsh environments. In wet or dusty spaces, moisture infiltration and unreliable wiring complicate maintenance and risk downtime. RoHS compliant, cULus listed, and IP67-rated deliver safer, regulator-ready installations across heavy industries. With 30A capacity at 277/480V and a four-pole design, it reduces wiring errors and extends service life. Engineered for harsh environments, the connector uses a nylon body, Santoprene elastomeric seals, and nickel-plated brass contacts to resist corrosion and wear. Its back-wiring method simplifies field wiring, while a 20 in-lbf torque specification ensures reliable terminal retention during vibration. This combination supports safer maintenance, faster field service, and lower total cost of ownership for industrial facilities.

IP67 watertight protection translates to dependable operation in exposure to rain, wash-downs, and dust; this reduces unplanned downtime and maintenance costs for outdoor enclosures and mobile equipment. The locking mechanism prevents accidental disconnection during vibration, ensuring continuous power delivery in rolling stock, conveyors, and on-site rigs. The four-pole, four-wire configuration with a 30A rating and 277/480V capability supports clean, code-compliant 3-phase power for large industrial machines. Back wiring simplifies field terminations and reduces install time, cutting labor costs and field error rates. A rugged nylon body paired with Santoprene seals delivers chemical and temperature resilience, while nickel-plated brass contacts resist oxidation and wear, delivering reliable current transfer under demanding conditions and extending connector life in harsh environments. The 20 in-lbf torque rating provides consistent, repeatable terminations, minimizing loosening from vibration and thermal cycling, ensuring electrical integrity across industrial automation panels and equipment enclosures. RoHS compliance and cULus listings support safe procurement and regulatory compliance for global manufacturing. Cord diameter range 0.43-1.15 in and back wiring enable flexible cabling choices, while the IP67 environmental resistance aligns with demanding enclosure standards and wash-down environments.

FAQs
Yes. The L1930CWBK uses back-wiring, supporting #18-10 AWG conductors in a four-pole, four-wire configuration rated for 30A at 277/480V. The terminal design and torque spec of 20 lbf-in ensure secure terminations even under vibration. This makes it straightforward to wire from control panels to motors or transformers without adapting conductors.
Key specifications include 30A amperage, voltage rating of 277/480V for 3-phase systems, four poles, and a back-wiring method. The device is designed for IP67 ingress protection and uses nickel-plated brass contacts with a nylon body, delivering reliable current transfer in harsh environments while meeting RoHS and cULus standards.
Ideal for outdoor panels, wash-down areas, and industrial equipment subject to vibration, the L1930CWBK supports 3-phase power distribution in conveyors, milling machines, and mobile equipment. The L19-30 configuration and watertight seal make it suitable for marine, agricultural, and factory automation environments requiring robust locking and moisture resistance.
The connector is RoHS compliant and cULus listed, signaling compliance with environmental and safety standards across North American and global manufacturing environments. These certifications reduce procurement risk, support regulatory approvals for machinery, and simplify supplier qualification for regulated projects.
By delivering a secure lock, reliable 30A, 277/480V operation, and back wiring for easier field terminations, the L1930CWBK reduces downtime, maintenance labor, and wiring errors. The rugged nylon and nickel-plated brass construction minimizes wear, translating to longer service life and lower replacement costs in demanding industrial settings.
