Product information
Overview
Key Features
- Current and power ratings: Rated operational current is 551 A at 40 °C, 494 A at 50 °C, and 438 A at 60 °C. At 400 V, the rated power is 315 kW in the standard circuit and 560 kW in the inside-delta circuit.
- Inside-delta performance: The inside-delta circuit has rated operational current of 954 A at 40 °C, 856 A at 50 °C, and 759 A at 60 °C, with a minimum load of 8%.
- Motor and device protection: The soft starter has intrinsic device protection, motor overload protection, thermistor motor protection evaluation, adjustable current limitation, and external reset.
- Control supply and connections: The control supply is AC, with a rated voltage of 230 V at 50 Hz and 60 Hz. The main current circuit uses busbar connections; auxiliary and control circuits use screw-type terminals.
- Mechanical installation: Dimensions are 510 mm wide, 640 mm high, and 290 mm deep. Mounting uses screw fixing; the vertical mounting surface is rotatable by +/-90° and tiltable by +/-22.5° to the front and back.
