250V 2PL/3WIRE LCK CONN (Product Description)
A 250-volt, 2-pole, 3-wire locking connector (LCK CONN) is a heavy-duty industrial twist-lock electrical connector used for safe, secure power connections in commercial and industrial environments.
Product Description
This is a locking-style electrical connector rated for 250V AC, designed for 2-pole, 3-wire systems (typically hot, hot, and ground or neutral depending on configuration).
The twist-lock mechanism ensures the plug and receptacle lock together firmly, preventing accidental disconnection caused by vibration, movement, or pulling on the cord.
This type of connector is commonly used in industrial machinery, generators, welders, and high-load equipment requiring a reliable 240–250V power connection.
In many cases, this corresponds to NEMA L6 series devices (such as L6-15 or L6-20) depending on amperage rating.
