FAQs
The L620RW supports #14-8 AWG conductors with back wiring and uses nickel-plated bronze contacts in a glass-filled nylon body. Plan for a 250 V, 20 A circuit with an L6-20 configuration and ensure the enclosure provides IP66/NEMA 4X protection for washdown or outdoor use. Use a compatible receptacle box to preserve sealing and locking integrity.
Key ratings include 20A current capability and 250V voltage with a two-pole, three-wire configuration (L6-20). Torque specs are 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG, ensuring secure terminations. Reliability is enhanced by corrosion-resistant nickel-plated bronze contacts and a durable thermoplastic/nylon housing suitable for industrial environments.
Yes. The L620RW carries IP66 and NEMA 4X protections along with NEMA 3/4/12 compatibility, making it suitable for outdoor areas, washdowns, and harsh production floors. Its watertight design and locking mechanism ensure secure connections even in vibration-heavy or wet conditions common to manufacturing and process facilities.
The L620RW is RoHS compliant and cULus listed, with NOM certification noted in its specifications. Its environmental ratings (IP66 and several NEMA enclosures) support compliance for industrial facilities seeking durable, code-aligned power distribution solutions for both indoor and outdoor use.
Expect low maintenance due to sealed construction, corrosion-resistant contacts, and durable thermoplastic/nylon housing. The locking design reduces unplugging incidents and downtime, improving uptime in automation lines. While initial costs may be higher than non-locking receptacles, the long-term ROI comes from fewer replacements, reduced maintenance, and compliance alignment.
