6. The selection tables are for normal use. If the AC motor drive requires frequent braking, increase the
Watts by two to three times.
7. Thermal Overload Relay (TOR), for 230V / 460V / 690V models:
Thermal overload relay selection is based on its overload capacity. A standard braking capacity of the
C2000 Plus is 10% ED (Tripping time=10 s). As shown in the graph below, a 460V, 110 kW C2000 Plus
requires the thermal relay to take 260% overload capacity for 10 seconds (hot starting) and the braking
current is 126 A. In this case, select a thermal overload relay rated at 50 A. The specification of each
thermal relay may vary among different manufacturers. Carefully read the specification before using it.
