It's built for distributed motor control on AS-interface networks, meaning you run the motor forward and reverse without a separate control cabinet. The 1.5 kW rating at 400 V AC-3 tells you it's sized for a standard 2 HP induction motor on a conveyor or pump — the AC-3 duty class covers starting and stopping squirrel-cage motors under load, which is the real-world use case. The setting range of 2.8 to 4 A matches the full-load current of that motor size. Operating temperature from -25 to +55 °C covers unheated warehouse floors and hot motor bays alike. ## AS-interface and brake integration This unit communicates over AS-interface (AS-i), not PROFIBUS DP — the bus protocol is AS-i, which is a two-wire network carrying both power and data for sensors and actuators. That makes it a drop-in for AS-i lines where you want reversing control plus feedback without pulling separate control cables. It also includes a motor brake output (400 V AC), so if your motor has an electromagnetic brake for holding a vertical load, the starter handles the brake coil timing directly — one less relay to add. ## Panel and mounting considerations The enclosure measures 270 mm high, 120 mm wide, and 190 mm deep — that's a compact footprint for a reversing starter with bus electronics and brake contact. The IP65 housing means it's surface-mount on a machine frame or wall bracket, not DIN-rail inside a cabinet — plan for gland-plate entry for the AS-i cable and motor leads.","metaTitle":"Siemens 3RK1322-1ES02-1AA3 AS-i Compact Reversing Starter, 1","metaDescription":"Siemens SIRIUS 3RK1322-1ES02-1AA3 AS-i compact reversing starter, 2.8-4 A, 1.5 kW at 400 V AC-3, IP65.
