Rated for 0.18 kW at 400 V AC-3 duty, it handles small three-phase motors — conveyors, pumps, fans — that draw between 0.45 A and 0.63 A full-load. The setting range is narrow; this is a fixed-size starter for a specific motor current, not a wide-adjustment overload. If your motor nameplate falls outside that band, this part won't cover it. The AS-interface protocol connection means it talks directly to the fieldbus without a separate gateway module — the starter carries two integrated inputs for limit switches or pushbuttons, and a motor brake output rated for 500 V DC / 1 A. That brake contact is a differentiator: it lets the starter control a holding brake on vertical-axis loads without an extra contactor. ## IP65 and the deployment context This starter is meant for machine-mounting in food processing, packaging lines, or material handling where washdown is routine. Below -25 °C the bimetal trip curve shifts; above +55 °C you'd need to derate or provide forced ventilation. ## Short-circuit performance and coordination The maximum short-circuit breaking capacity (Icu) is rated at 50,000 A at 400 V. The circuit-breaker type of short-circuit protection (Type 2 coordination) lets you use a standard motor-protective breaker ahead of it, keeping selectivity simple. The housing measures 270 mm high, 120 mm wide, and 190 mm deep. That's a compact footprint for a fully self-contained starter with AS-i communication, brake output, and two inputs. It mounts directly to a machine frame or sub-panel via the IP65 enclosure — no DIN rail required. The 120 mm width is the same as a standard 8-module terminal block assembly, so it fits neatly in a gland-plate cutout or a small junction box.","metaTitle":"Siemens 3RK1322-0GS02-0AA4 AS-i Compact Starter, 0.18 kW","metaDescription":"Siemens SIRIUS AS-i compact starter, direct-on-line, 0.45-0.63 A, 0.18 kW at 400 V AC-3, IP65, with brake contact.
