It's a self-contained motor start-and-protect unit rated for 1.9 kW at AC-3 duty on a 400 V three-phase line, with a setting range of 3.5 to 5 A per the bimetal overload relay. The IP65 enclosure means this unit is designed for distributed mounting directly on the machine or conveyor frame — not inside a central control panel — so it can live in washdown zones or dusty environments without an additional cabinet. The 3.5 to 5 A setting range on the bimetal relay lets you dial in the full-load current of the connected motor within that window. The IP65 rating is not just about dust and water jets — it means the enclosure seals against hose-directed water, so this unit is suitable for food processing lines, car wash bays, or any area where washdown is part of the sanitation cycle. ## AS-Interface integration and connectivity This starter communicates over AS-Interface (AS-i) protocol, not PROFIBUS DP. That means it connects to the AS-i yellow flat cable via a standard piercing technique — no shielded twisted pair, no termination resistors. The unit has two integrated digital inputs for local sensors (e.g., limit switches or presence detectors) and a motor brake output rated for 24 V DC / 3 A. The main circuit connection uses tab terminals, so you'll need mating fast-on connectors for the motor and power cables.","metaTitle":"Siemens 3RK1322-1FS02-0AA1 AS-i Compact Starter, 3.5-5 A, IP","metaDescription":"Siemens 3RK1322-1FS02-0AA1 AS-Interface compact starter.
