The 1SFA895019R7000: The 840 A in-line rating (Ie) is the continuous current the softstarter can handle in a standard motor circuit — this decides the cable and contactor sizing upstream. The 450 kW at 400 V figure tells you the maximum motor power it can start in-line; for inside-delta wiring, that jumps to 800 kW at 400 V, which is the configuration used to reduce the current through the main thyristors for larger motors. The 400-690 V AC main circuit voltage range covers low-voltage networks from 400 V three-phase up to 690 V industrial supplies — common in mining, cement, and marine installations. The built-in electronic overload protection eliminates the need for a separate overload relay, saving panel space and wiring.
Integration notes
The main circuit terminals are bars (hole diameter 12.5 mm), sized for large cable lugs or busbar connections typical of high-current panels. The control circuit connects via rigid 1 x 2.5 mm² wire with a tightening torque of 0.5 N·m. The FieldBusPlug standard communication interface allows direct connection to a fieldbus network via an optional plug-in module — no separate gateway needed. Ambient operating temperature range is 0 to +50 °C, with a 115 % service factor for continuous overload capability.
