FAQs
The L1730CW supports back wiring with #18-10 AWG conductors and a torque rating of 20 lbf-in, enabling reliable terminations in industrial feeder cables. Its three-pole, four-wire configuration (grounding 4) aligns with L17-30 plugs and receptacles, simplifying field upgrades and retrofit projects while ensuring consistent mechanical grip during mating and disconnection cycles.
Rated for 30A and 600V, the L1730CW carries an IP67 rating for water and dust ingress resistance and conforms to NEMA L17-30 configurations. This makes it suitable for harsh environments, including washdown areas and outdoor use, where vibration and contaminants are common, ensuring continuous performance and regulatory alignment.
Yes. The IP67-rated, watertight locking design, combined with a nylon body and Santoprene seal, provides robust ingress protection and vibration resistance. The rugged construction supports outdoor equipment, conveyors, and industrial machinery in environments with exposure to moisture, dust, and cleaning processes, reducing maintenance frequency and replacement costs.
The connector is RoHS compliant and cULus Listed NOM, offering regulatory confidence for North American applications. While CE is not indicated in the data, these certifications support compliance for industrial facilities seeking RoHS and recognized safety listings for electrical components.
The locking mechanism, back-wiring capability, and durable materials (nickel-plated brass contacts, Santoprene elastomer, and nylon housing) deliver dependable performance with reduced downtime. Expect lower maintenance costs due to fewer field failures, easier terminations during service, and longer service life in tough industrial settings, supporting a favorable total cost of ownership.
