FAQs
The L1730CWBK supports back wiring and accepts #18-10 AWG conductors, allowing quick terminations inside control panels. For best results, prepare clean terminations, torque to 20 lbf-in, and verify wire insulation clearance to maintain the IP67 seal. This reduces field re-termination and improves reliability in vibrating environments.
Key specs include a 30A amperage rating, 600V voltage rating, 3Ø L17-30 NEMA configuration, and a four-wire arrangement with grounding. The connector is designed for industrial loads up to 30A, ensuring secure power delivery to motors and controllers while maintaining a robust ingress protection profile.
Yes. With IP67 enclosure protection and NEMA 4X/4/6/parity ratings, the L1730CWBK is intended for washdown, outdoor, and harsh environments. The Santoprene seal, nylon body, and nickel-plated brass contacts provide reliable sealing and corrosion resistance in moisture-prone facilities like food processing, water treatment, and outdoor equipment.
The connector is RoHS compliant and cULus Listed, supporting regulatory compliance and safe electrical installation. Its IP67 rating provides environmental protection, and the NEMA L17-30 configuration suits industrial three-phase power applications while meeting safety standards for heavy-duty equipment.
The locking design, rugged materials, and IP67 protection reduce maintenance intervals and downtime, extending component life in demanding environments. With ease of back wiring, faster field terminations, and strong regulatory compliance, operators experience lower total cost of ownership and improved uptime for motors and industrial controls.
