DC Side Switching
The rectifier brake circuit must be protected with fuses independent from the motor
circuit. A 2 amp class CC fuse is recommended for Fbrk in the diagram below. The
contact rating of the AC side relay or contactor (Kbrk_ac) should be minimum 5 amps
with the minimum voltage based on the applied AC voltage. 125VAC for 120V supply,
250VAC for 208V or 230V supplies, and 600VAC for 400 or 480V supplies. The DC side
contactor (Kbrk_dc) must be a three way phase power contactor rated for 600VAC and
minimum of 9 amps inductive (AC3). All three contacts are wired in series as indicated in
figure 11.
