The Pass & Seymour L3720R is a one-piece locking receptacle designed for higher voltage installations, rated at 347 VAC and 20 A. Built with a compact nylon face and body, the unit is ultrasonically welded for robust strength and impact resistance, helping to withstand demanding industrial environments. The face is color-coded by voltage to aid quick identification and correct mating with compatible devices, while clearly marked NEMA configuration, rating, and third-party listings on each unit’s face support proper selection and inspections. The single-piece solid brass mounting strap eliminates rivets that can loosen over time, contributing to reliable alignment during installation and reducing maintenance needs. Back-wire capability is available via side and external screw-pressure-plate terminals, accommodating #14 through #10 AWG conductors for flexible field wiring.
This receptacle is configured as a single locking type with two poles and three terminals, aligning with L24-20R family geometry. The combination of nylon construction and brass contacts provides both durability and solid conductivity with resistance to heat-rise typical of high-current, high-voltage connections. The unit is intended for use in facilities where locking connections are preferred for vibration resistance and to prevent accidental disconnection, such as power distribution panels, industrial equipment rooms, or areas requiring secure, non-terminating plug-in outlets. When selecting this device, verify the voltage, current rating, and locking compatibility for your specific application and ensure proper mating hardware and enclosure protection are used.
Package is listed as an individual receptacle, suitable for field wiring with #14–#10 AWG conductors. As with all locking devices, ensure proper torque and secure mounting to maintain a reliable electrical interface. The 347 VAC rating indicates suitability for systems in regions or installations where this voltage level is standard, but always confirm compatibility with the existing electrical system and any applicable local codes or standards.
