The 1 A AC-3 rating at 400 V governs the motor size this unit can handle — it is sized for fractional-horsepower reversing applications, not main line drives. Control supply is 20.4 to 26.4 V DC, typical for AS-Interface bus-powered devices. The main circuit operating voltage spans 340 to 440 V AC at 50/60 Hz, covering standard 400 V three-phase networks across Europe and much of Asia. With IP54 protection, this starter is suited for installation inside a control cabinet or in a protected enclosure where limited dust and splash ingress is expected — not for direct washdown zones. The housing dimensions (245 mm wide, 215 mm high, 205 mm deep) and mounting position flexibility (±180° rotation on a vertical surface, ±22.5° tilt) simplify panel layout when space is tight.
This is a bus-connected reversing starter for AS-Interface networks (AS-Interface protocol supported, PROFINET and PROFIBUS DP not supported). It provides 2 digital inputs for local feedback or pushbuttons, and the motor brake output is built in. The unit includes integrated short-circuit protection via circuit-breakers, so it can be a standalone motor branch in a distributed I/O architecture — common in material handling, packaging, and small assembly lines where AS-Interface is the fieldbus backbone.
