The Hubbell HBL2741 is a premium-grade industrial locking plug designed for high-performance electrical applications requiring a secure NEMA L16-30P connection. Part of Hubbell's renowned Insulgrip line, this device is engineered to withstand the rigors of heavy industrial environments while providing superior electrical safety and ease of installation. Rated for 30 Amperes and 480 Volts AC (3-Phase), it features a 3-Pole, 4-Wire Grounding configuration suitable for powering motors, industrial machinery, and power distribution units.
Constructed from high-impact modified nylon, the housing is built to resist cracking, chemicals, and extreme temperatures. The distinctive black and white color coding identifies it as a Hubbell industrial standard device. Internally, the plug features individual wiring chambers that completely isolate each conductor, significantly reducing the risk of flashover or short circuits. The clear polycarbonate terminal retainer allows for visual inspection of wire terminations without disassembling the device, ensuring quality control during installation.
One of the standout features of the HBL2741 is its powerful cord retention system. The integral Vari-Size insert accommodates a wide range of cord diameters, from 0.350 to 1.150 inches, eliminating the need for extra parts. The offset cord grip screws provide high retention force without crushing the cable jacket, preserving the integrity of the power cord over time. Heavy-duty brass alloy blades are designed for maximum conductivity and minimal heat rise, ensuring long-term reliability even under continuous load.
This plug is UL Listed and CSA Certified, meeting strict safety standards for grounding and locking devices. Whether used for facility maintenance, OEM equipment manufacturing, or electrical infrastructure upgrades, the Hubbell HBL2741 delivers the robust performance expected by electrical professionals.
