Our products are "dual rated" for different product safety standards around the world. The electrical connector will always be rated for what each country allows based on how the different agencies test and rate these industrial electrical components.

This chart is used to indicate the voltage and frequency in accordance to IEC 60309-1 (Series II). The system has been designed to maximize safety, avoid mismatching, and promote interchangeability among manufacturers. A clock face is used to represent the location of the ground sleeve for a specific voltage system. The positions of the ground pins are relative to the socket’s keyway and are designated as a clock hour position depending on the voltage rating of the part.

In North America, the color orange is reserved for devices for 125/250 V~ and the color gray is reserved for devices for 277 V~.
