The Siemens 3RK1322-0ES02-1AA0 is an AS-Interface compact reversing starter from the SIRIUS family — a fully enclosed motor starting and reversing unit rated for 0.1 kW at AC-3 duty on a 400 V line. The setting range spans 0.28 to 0.4 A, with bimetal motor protection and electromechanical switching contacts. The IP65 enclosure means this starter is built for washdown environments — food processing, beverage lines, or anywhere hosedown is routine. The housing and optics withstand direct spray, so it mounts directly on the machine frame, not tucked away in a panel.
AS-Interface integration and connections
Communication is via AS-Interface protocol (no PROFIBUS DP on this variant), with two integrated inputs for local sensors or pushbuttons. The main current circuit connects through tab terminals — a 9-pole motor outgoing feeder and a 9-pole power connection. That tab-terminal design means crimp-on female quick-connects, not screw terminals; verify your cable terminations match before the line goes down.
