DC Contactor Crimp Lug Kit Specifications
Use the information provided in the table below to assist you in ordering the
correct Lug kit for your application.
Alternate Dynamic Brake Resistor Kits and DC Output Contactors
The following alternate dynamic brake resistor kits and/or DC output contactors
may be used with the corresponding PowerFlex DC drives but must be sourced
separately from the drive.

(1) The Rated Motor Armature Current is taken directly from the motor nameplate or motor data. The current listed in this column is the maximum current allowed for the
Armature Conductor Size (column 3) and the DC Contactor Rating (column 2).
(2) The armature conductors are sized by multiplying the Rated Motor Armature Current by 1.25 as provided for in NEC 420-22 (1987). The DC lug ratings are determined from
NEC Table 310-16 (1987) for copper conductors, insulation temperature rated at 75 °C (167 °F) at an ambient temperature of 30 °C (86 °F). If conditions are other than
shown in NEC Table 310-16, then refer to application codes.
(3) The dynamic braking (DB) conductors are sized as in footnote 2 above, but at half ampacity due to the short time duration of current flow in these conductors, and has
been sized to satisfy NEMA Standard ICS 3-302.62 - Dynamic Braking. If the load inertia is larger than that of the motor, calculations must be made to determine correct
conductor sizing and DB resistor wattage per NEMA Standard ICS 3-302.62.
