Key Features
Rated motor power is 630 kW in standard circuit and 1 100 kW in inside-delta circuit at 40 °C.
Rated operational current is 1 076 A at 40 °C, 970 A at 50 °C, and 880 A at 60 °C; inside-delta values are 1 864 A, 1 680 A, and 1 524 A respectively.
Operating voltage is 200 … 460 V in both standard and inside-delta circuits. The AC control supply is 230 V at 50 Hz or 60 Hz.
The soft starter has an integrated bypass contact system, thyristors, intrinsic device protection, motor overload protection, thermistor motor protection evaluation, external reset, adjustable current limitation, and a motor brake output.
The main current circuit uses busbar connection; auxiliary and control circuits use screw-type terminals. Fastening is by screw fixing.
This is a phased-out product with support in its final year. The preferred successor type is 3RW5558-6HA14.
