It's an electromechanical reversing starter with bimetal motor protection and circuit-breaker-based short-circuit protection, all housed in an IP65 enclosure that handles washdown environments. Communication is via AS-interface protocol (not PROFIBUS DP), with two integrated inputs and a motor brake output (500 V DC / 1 A) built in. The main current circuit connects through tab terminals, typical for quick field wiring in distributed motor starter applications. The 0.55–0.8 A setting range covers small reversing motor loads — think fractional-horsepower conveyors, diverters, or valve actuators. The AC-3 rating at 400 V (0.21 kW) is the motor-switching duty: it's the current the contacts handle during starting and plugging, not the resistive-heating rating. For a 0.21 kW motor at 400 V three-phase, full-load current sits around 0.5–0.6 A, so this starter is sized correctly for that specific motor frame. In a panel with a high-available-fault-current bus (common in industrial distribution), this rating means you don't need an upstream current-limiting fuse to protect the starter itself. For a BOM line that calls out 3RK1322-0HS02-1AA4, the fit is confirmed by the setting range (0.55–0.8 A), the reversing function, the AS-i bus interface, and the IP65 enclosure. The tab-terminal main connections and 9-pole motor/power connectors are specific to this variant — verify the connector pattern matches your existing harness before committing the order.","metaTitle":"Siemens 3RK1322-0HS02-1AA4 AS-i Compact Reversing Starter, 0","metaDescription":"Siemens SIRIUS AS-i compact reversing starter, 0.55–0.8 A setting range, AC-3 0.21 kW at 400 V, IP65, with brake contact and integrated inputs.
