The current setting range spans 0.6 to 2.18 A, covering motor sizes from 0.18 kW up to 0.75 kW at 400 V. The IP65 enclosure means this unit mounts directly on the machine frame or conveyor section, not inside a control cabinet — it handles washdown environments and dust ingress common on food-and-beverage or material-handling lines. Built-in bus communication via AS-interface protocol eliminates separate control wiring for start/stop and direction commands. The integrated motor brake output (500 V DC / 1 A) handles internally supplied brakes directly, saving an external brake rectifier. The solid-state motor protection (type of assignment 1) provides overload and phase-loss detection without bimetallic relays. The setting range of 0.6 to 2.18 A lets you dial in the exact motor FLA — a 0.75 kW motor at 400 V typically draws around 1.8 A, well within the adjustable window. The 190 mm depth and 120 mm width are the footprint for panel layout if you do mount it in an enclosure, but the IP65 rating makes that unnecessary in most cases — it's designed for distributed mounting near the motor. For a BOM line or critical spare, this is a fast mover in the SIRIUS AS-i compact starter family — it covers the common 0.75 kW motor size on 400 V lines. The solid-state design gives it a longer mechanical life than electromechanical reversing starters, which matters for high-cycle applications like conveyor diverters. Mount the unit directly on the machine frame using the four mounting holes in the IP65 housing — no DIN rail required. The 9-pole power connection carries the motor leads, brake wiring, and AS-i bus in one plug, reducing field wiring time. Two integrated inputs accept limit switches or sensors without an external I/O block. The fuse-based short-circuit protection (design of short-circuit protection: fuse) means you need a gL/gG fuse upstream sized per the motor branch circuit — not a circuit breaker.","metaTitle":"Siemens 3RK1322-0AS12-1AA4 AS-i Reversing Starter, 0.8 kW, I","metaDescription":"Siemens 3RK1322-0AS12-1AA4 AS-i compact reversing starter with solid-state motor protection.
