The 1SFA894007R7000: The 72 A inline rating (124 A inside-delta) and 37 kW at 400 V tell you the motor size this softstarter can handle in a standard wye configuration. Inside-delta wiring boosts the current capacity to 124 A, which lets you pair it with a larger motor if the panel wiring supports that topology — useful when the motor FLA sits between the two ratings. The 0-120 second ramp time covers soft starts from a quick 2-second kick to a gradual 2-minute acceleration, so it fits conveyors, pumps, and fans that need a gentle torque build-up. The built-in electronic overload (adjustable 1.5-7x Ie) replaces a separate thermal relay, which simplifies the BOM and cuts panel wiring. The 115 % service factor means it can run continuously at 15 % over the rated current without tripping — handy for intermittent overloads on a crusher or mixer.
The screw terminals accept rigid cable up to 95 mm² on the main circuit, so it connects to standard power cabling without adapters. The FieldBusPlug communication port lets you hook it to a higher-level controller for start/stop commands and status feedback — no separate I/O module needed for basic control.
