⋆ Horsepower/kW ratings shown in the table above are for reference. The final selection of the manual starter depends on the actual motor full load current.

Note:In applications with 140M-C_N, 140M-D_N and 140M-F_N as the short circuit protection device of heavy duty starting motors, the rated operational current I_e of the above devices must be over-dimensioned with following factors:

             CLASS 10 = 1.00
             CLASS 15 = 1.22
             CLASS 20 = 1.42
             CLASS 25 = 1.58
             CLASS 30 = 1.73

⋆ The Hp and kW ratings shown are for reference only. They allow for a magnetic trip setting of at least up to 13X the motor FLA. However, the final selection of the MCP should be made based on motor full load current and the requirements of local electrical codes.
‡ The interrupting rating for MCPs is dependent upon the controller used. Please contact your local Rockwell Automation sales office or Allen-Bradley distributor for further information.
