LCK.CONNC.20AMP/125/250V/3PL

LCK CONNC 20AMP / 125-250V / 3PL (Product Description)

A 20-amp, 125/250-volt, 3-pole locking connector (LCK CONNC) used for industrial and commercial twist-lock electrical power connections.

Product Description

This is a 20A locking connector (female or male cable-end, depending on model) designed for use in 3-pole, 3-wire (3PL / 3P3W or 3P4W depending on system) electrical circuits. It supports dual-voltage operation (125V or 250V AC) and is commonly used in light industrial power distribution and equipment connections.

“LCK CONNC” is a shorthand abbreviation for locking connector, meaning it uses a twist-lock mechanism that secures the plug into the receptacle so it cannot easily disconnect due to vibration or pulling.

Industry equivalents typically correspond to NEMA L10-20 or similar locking configurations, depending on exact pin layout.
