The control supply for the device is 110…250 V AC and the starter uses three‑phase control with soft ramp-up and ramp-down capability plus adjustable current limitation — features that reduce mechanical shock and limit inrush current for large pumps, compressors, conveyors and other heavy industrial drives. This SKU includes an integrated bypass contactor to reduce heat loss during run and provides built‑in motor overload protection with thermistor input capability and analog output functionality for remote monitoring. The unit is supplied in an IP00 enclosure and is engineered for continuous industrial use at a rated ambient of 40 °C without derating. \u003c\/p\u003e\n\u003c\/section\u003e \u003csection id=\"technical-attributes\"\u003e \u003ch3\u003eKey Soft Starter Attributes\u003c\/h3\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003eRated operational current (Ie)\u003c\/th\u003e \u003ctd\u003e570 A (rated at 40 °C)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eMotor power range\u003c\/th\u003e \u003ctd\u003eInline: up to 315 kW at 400 V; Inside‑delta: up to 560 kW at 400 V\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth\u003eSupply voltage\u003c\/th\u003e \u003ctd\u003e200 … 480 V AC (main).
