IEC 60309 includes “plugs, socket-outlets and couplers for industrial purposes”. The IEC 60309 standard puts an emphasis on safety through a unique arrangement of pins and earth/ground to ensure that only compatible devices are able to mate. Further, this standard may optionally include a pilot contact that plugs in last when connecting and first when disconnecting to reduce the likelihood or arcing, which may cause damage to the individual or device. The pin and sleeve design of this standard provides some degree of weatherproofing, indicated by its IP (Ingress Protection) marking. Most common are the IP44 and IP66, which provide splash-proof protection and watertight protection, respectively. Overall, this standard is common in open-air conditions where high power draw is required and protection from individuals, dust, water and chemicals is desired.

General Information:

IEC 60309 includes “plugs, socket-outlets and couplers for industrial purposes”. The IEC 60309 standard puts an emphasis on safety through a unique arrangement of pins and earth/ground to ensure that only compatible devices are able to mate. The pin and sleeve design of this standard provides some degree of weatherproofing, indicated by its IP (Ingress Protection) marking.  

IP44 is known as the "Splashproof" Rating, which breaks down to sealing against solids no smaller than 1.0mm and spraying water at the connection from any angle. Overall, this standard is common in open-air conditions where high power draw is required and protection from individuals, dust, water and chemicals is desired. The IP code, as defined by standard IEC 60529, classifies the degrees of protection provided against the intrusion of solids and liquids.

NEMA L6-15R Twist Lock Connector

NEMA L6-15R Twist Lock Connector

General Information:

The NEMA L6-15R is a grounded (Hot-Hot-Neutral) Connector that is rated up to 250V and 15A. The connector couples with the L6-15P and locks into place preventing nuisance disconnection. This feature makes it popular in commercial and industrial settings where there is high traffic. This connector is common in the L6-15 Extension Cord Series where it is used to extend power from a L6R wall receptacle or connector to a certain location for convenience.

What does the NEMA L6-15R Connect to?




NEMA L6-15P Plug
NEMA L6-15P Inlet
The NEMA L6-15R Locking Connector is design to be twisted into place with the NEMA L6-15P Plug or Inlet. The plug is used on many different power cords, and the Inlet can be found on a variety of Industrial equipment using 250V and 15A.
