Hubbell HBL4573VBK locking plug overview

The Hubbell HBL4573VBK is a NEMA L6-15P locking plug rated for 15 A at 250 V AC single phase. Its two-pole, three-wire design provides a secure polarized connection with grounding for industrial and commercial equipment. The nylon housing withstands impacts and chemical exposure while meeting CSA C22.2 No.42, UL 498 and Federal Specification W-C-596.

Who should use this plug

This plug suits installers who need a locking 15 A 250 V connection for portable cords between .220 in and .660 in diameter using stranded copper wire from 18 AWG to 12 AWG. It is built for indoor dry locations with an IP20 rating and an operating range of -40 °C to 75 °C. Buyers who need a straight-blade connector, a higher amperage rating, a different NEMA configuration or an outdoor-rated device should look at other options.

What to verify before ordering

Confirm that your equipment requires a NEMA L6-15P plug rated for 15 A at 250 V AC single phase. Check that the cord outer diameter falls within the .220 in to .660 in range and that the conductors are stranded copper between 18 AWG and 12 AWG. Ensure the installation environment is an indoor dry location compatible with an IP20 rating and that the -40 °C to 75 °C temperature limits meet your application requirements.
