That 0.1 kW figure is the operating power at 400 V, not the resistive-heat rating; it governs the motor size this starter can handle in a standard three-phase induction motor application. Communication runs over AS-interface protocol (no PROFIBUS DP onboard), with two integrated inputs for local sensors or pushbuttons. The part includes a motor brake output contact, so a holding brake on a vertical-axis motor can be controlled directly from the starter without an external relay. ## Short-circuit breaking capacity and coordination The maximum short-circuit breaking capacity (Icu) at 400 V is 50 000 A. The short-circuit protection is designed around circuit-breakers, per the product design. The 270 mm height, 120 mm width, and 190 mm depth define the panel space required; verify clearance for the AS-i bus cable entry and the brake contact wiring.","metaTitle":"Siemens 3RK1322-0ES02-0AA3 AS-i Compact Starter, 0.28-0.4 A,","metaDescription":"Siemens 3RK1322-0ES02-0AA3 AS-interface compact DOL starter, 0.28-0.4 A setting range, 0.1 kW at 400 V AC-3, IP65, with integrated brake contact.
