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
