FAQs
The L1520CW supports back wiring with conductors in the #18-10 AWG range, enabling straightforward terminations in control panels or equipment enclosures. Ensure the device is de-energized, insert wires into the back-wire terminals to the specified torque (14-16 lbf-in), and verify solid mechanical and electrical contact. Use appropriate strain relief and verify polarity during final assembly.
The L1520CW provides a 20A amperage rating, 250V voltage rating, and a 3Ø configuration (L15-20). It features IP67 protection, suitable for immersion and washdown conditions, and aligns with RoHS, NOM, CSA, UL, and cULus standards. These specifications support reliable performance in harsh environments and improve equipment uptime.
Yes. With IP67 protection, NEMA 4/4X/6/6P compatibility, and watertight sealing, the L1520CW is designed for outdoor and washdown applications. The yellow nylon body and Santoprene elastomeric seal provide robustness against moisture, while nickel-plated brass contacts offer corrosion resistance. This makes it a dependable choice for outdoor motors and rugged process equipment.
The L1520CW is UL Listed, cULus Listed, NOM certified, and CSA certified, with RoHS compliance. These certifications ensure product safety, environmental compliance, and compatibility with regional electrical codes. For manufacturers and integrators, using certified components reduces regulatory risk, simplifies audits, and supports customer qualification in regulated markets.
The locking design provides secure, vibration-resistant connections, reducing intermittent faults. Back-wiring simplifies field terminations, speeding maintenance tasks. The watertight construction minimizes ingress-related failures, lowering downtime and replacement costs. Over the equipment lifecycle, reliability improvements translate to lower maintenance labor, fewer unplanned outages, and a faster return on investment.
