Alternate Dynamic Brake Resistor Kits and DC Output Contactors
The following alternate dynamic brake resistor kits and/or DC output contactors can be used with the corresponding PowerFlex DC drives
but must be sourced separately from the drive.

Armature Current

A DC
(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 that is allowed for the Armature
Conductor Size (column 3) and the DC Contactor Rating (column 2).

Armature Conductor Size

AWG
(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 that is 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.
dB Conductor Size
(3)
AWG
(3) The dynamic braking (dB) conductors are sized as in footnote 2, 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 the motor inertia, calculations must be made to determine correct conductor sizing and dB resistor wattage per
NEMA Standard ICS 3-302.62.
