How to find the part number
Follow the steps below to locate and build the part number you need. Page numbers refer to Schneider Electric’s Digest 177.
If you don’t have a copy of the product catalog, please request one from your local representative or visit www.schneider-electric.us.
Step 1: Choose your power base (mandatory)
• Step 1a: Locate the correct page in the Digest
> If it’s IEC non-reversing, go to page 18-23, Table 18.83
> If it’s IEC reversing, go to page 18-25, Table 18.90
> If it’s NEMA, go to page 16-12, Table 16.30.
• Step 1b: Match the motor voltage and horsepower from your worksheet to the values in the appropriate
column in the Digest
• Step 1c: Follow that row to the right to locate the part number
Step 2: Choose your control unit (mandatory)
• Step 2a: Locate the correct page in the Digest
> Go to page 18-25, Table 18.91 and 18.95 for IEC; go to page 16-12, Table 16.32 for NEMA
• Step 2b: Match the information on #9 of your worksheet to the values in the appropriate column in the Digest
> Complete the catalog number by adding the appropriate voltage code from Table 18.92 for IEC; Table 16.31 for NEMA
Step 3: Choose auxiliary contact function modules (optional)
• Locate the correct page in the Digest
> Go to page 18-23, Table 18.86 for IEC; go to page 16-12, Tables 16.33 & 16.34 for NEMA
