The 1SFA894020R7000: The 0-120 second ramp time lets you tune acceleration for conveyors, pumps, or fans so the load doesn't jerk the driveline. Starting capacity is 3x Ie for 15 seconds, which covers most standard induction motor starts without oversizing.
The 1050 A in-line rating is the number you spec against the motor nameplate FLA — it's the continuous current the softstarter carries without bypass. The 1810 A inside-delta rating applies when you wire the softstarter in the motor's delta legs, which reduces the current through each device phase by a factor of √3; that's the configuration that gets you 1000 kW from a single unit. Built-in electronic overload protection (1.5-7x Ie current limit function) means you can omit a separate overload relay from the starter assembly — one less component to wire and panel-space to budget. The run, fault, bypass, and overload signal relays give the PLC a clean status picture without adding interface modules. Main circuit terminals are bars with a 12.5 mm hole — expect to land lugs, not ferrules. Control circuit torque is 0.5 N·m; the supply circuit accepts rigid 1 x 2.5 mm². The FiledBusPlug (Standard) communication interface lets you drop a fieldbus connector directly onto the unit without a separate gateway card.
RoHS compliance is declared as 'no declaration needed' — the part falls under WEEE Category 4 (Large Equipment, any external dimension >50 cm), B2B scope. The relevant manual is 1SFC132003M0201 and the datasheet is 1SFC132005C0201.
