The setting range spans 9 to 12 A, adjusted via the bimetal relay. It includes a motor brake output, two integrated inputs, and communicates over AS-Interface (not PROFIBUS DP). The IP65 enclosure means the entire assembly — starter, bus interface, and connections — is rated for washdown environments, so it mounts directly on the machine frame or conveyor line without a separate control cabinet. The 5.5 kW AC-3 rating at 400 V defines the maximum induction motor it can switch under typical starting conditions — think small conveyors, pumps, or fans. The 9-12 A setting range on the bimetal overload matches motors drawing full-load current in that band; if your motor nameplate FLA is 10.5 A, this starter lands right in the middle of the adjustment window. This is a self-contained unit — no DIN rail required, no separate contactor and overload to wire. The IP65 housing (270 x 120 x 190 mm) has tab terminals for the main circuit and a 9-pole motor outgoing feeder plus a 9-pole power connection. The AS-Interface bus cable daisy-chains through the unit, and the two integrated inputs can take signals from pushbuttons or sensors directly, reducing junction box wiring. The brake output is a separate contact rated for the motor brake coil, so you don't need an extra interposing relay for holding-brake applications.","metaTitle":"Siemens 3RK1322-1KS02-1AA3 AS-i Compact Reversing Starter, 5","metaDescription":"Siemens 3RK1322-1KS02-1AA3 AS-Interface compact reversing starter.
