Part number decoding

Let us look at the Pin and Sleeve part number structure. One, in particular, HBL560C9W, is manufactured in America by Hubbell Wiring Devices. The first three letters, HBL, is what Hubbell designates in their product line as Heavy Duty. The North American offering is 20 amp,30 amp, and 100 amp. Voltages range from 125 volts up to 600 volts in both single and three-phase. 

The Key to the International Electric Code (IEC 309), a worldwide designation, starts with the first number.  

Let us break down the numbers in this part number.
