Our 5119 AL series features the 3-prong, North American, Locking NEMA L6-20P Plug with the Down Angle IEC-60320-C19 Auto-Lock Connector. The IEC Auto-Lock C19 is an internal mechanism that holds the pins of the C20 Plug or Inlet to keep your device from being accidentally unplugged! These components are sturdy yet unplug with ease whenever you want to remove the power cord! These locking power cords are ideal for powering your high voltage/ high current equipment. On one end, the plug connects to a Locking NEMA L6-20R outlet or receptacle, while on the other end the IEC-60320-C19 Connector can power servers and tele-communications devices, as well as many more devices and electronics which have the IEC-60320-C20 Inlet. Additionally, this power cord features a twist-lock plug which rotates to lock into the matching receptacle. This down angle power cord is ideal for use in confined spaces because it eliminates stress placed on the conductors and strain relief. The definition of a down angle connector is that when facing the equipment with the connector installed ground-pin-up, the cord trails down and away from your equipment. The 5119.072AL is on 12/3 SJTW cable. It carries the UL and C-UL approvals and is rated at 20A - 250V.
