FAQs
The CRL1620C supports a three-pole, four-wire L16-20 configuration rated for 20A at 480V, using a back-wiring method. It accepts #14-8 AWG conductors, enabling flexible field wiring for most industrial panels and motors. This combination simplifies panel design and speeds up commissioning while maintaining a secure, Locking connector interface.
The connector uses a nylon body with nickel-plated brass contacts to provide robust corrosion resistance, aiding reliability in outdoor and harsh indoor environments. This reduces maintenance frequency and the risk of connection failures due to environmental exposure, which translates to higher uptime for machinery and distribution systems.
Yes. The CRL1620C is RoHS Compliant and cULus Listed NOM, aligning with global regulatory requirements and easing compliance during audits and supplier qualification. These certifications help ensure procurement teams meet sustainability and safety standards without sacrificing performance.
Common applications include industrial machinery, power distribution panels, and other equipment powered by 480V three-phase systems. The locking design, back-wiring capability, and mechanical robustness make it suitable for motors, drives, and distributed control setups in manufacturing environments.
The locking mechanism reduces the likelihood of accidental disconnections, while the corrosion-resistant construction lowers replacement and service costs over time. Together with standardized wiring and regulatory compliance, this translates to lower maintenance labor, fewer downtime events, and improved total cost of ownership for industrial installations.
