Hubbell HBL2351 Locking Plug 20 A 600V AC

The Hubbell HBL2351 is a NEMA L9-20P locking plug rated for 20 amps at 600 volts AC. It features a straight connection orientation with three blades and two poles in a single-phase configuration. The nylon housing comes in black and white and provides chemical and impact resistance. Screw terminals accept cable diameters from 0.36 to 0.93 inches.

Industrial power connections needing secure locking

This plug suits industrial environments where a grounded, polarized connection must resist vibration and accidental disconnection. It is built for standard wiring with a face diameter of 1.97 inches. Buyers who need a non-locking straight blade or a different NEMA configuration should look elsewhere. The device is not intended for low-voltage signal or data applications.

20 A capacity with 600V AC rating

The 20 amp rating handles typical industrial equipment loads within the 600V AC limit. The screw terminals provide reliable termination for cables up to 0.93 inches in diameter. Headroom exists for continuous operation at rated current when properly installed. The plug runs out of capacity beyond 20 amps or voltages above 600V AC.
