It's designed for distributed motor control on AS-Interface networks, eliminating the need for a central control panel for small motor branches. Rated for 0.9 kW at 400 V AC-3 duty, the setting range covers 1.8 to 2.5 A, making it suitable for small three-phase motors like those driving conveyors, fans, or pumps in decentralized layouts. The 1.8–2.5 A setting range matches the full-load current of a 0.75–0.9 kW motor at 400 V; the bimetal overload tracks motor heating directly, so you set it to the motor nameplate FLA. Tab terminals for the main circuit mean you need mating 6.3 mm fast-on receptacles — not screw clamps. The 9-pole motor and power connectors are pre-wired; the two integrated inputs let you connect local sensors (e.g., limit switches or emergency stops) directly into the AS-i node without extra I/O blocks. ## Integration notes The 190 mm depth, 120 mm width, and 270 mm height (–) define the envelope for machine-mounted installation. It's not a DIN-rail device — it bolts directly to a mounting plate or machine frame. The AS-i bus connection uses the standard yellow flat cable; the two integrated inputs are M12, typically for PNP sensors. No PROFIBUS DP onboard — this is strictly AS-Interface. If your network is PROFIBUS, you'd need a gateway. The motor brake output is absent, so separate brake control is required for holding-brake motors.","metaTitle":"Siemens 3RK1322-1CS02-0AA0 AS-i Compact Starter, 1.8-2.5 A,","metaDescription":"Siemens 3RK1322-1CS02-0AA0 AS-i compact direct starter, electromechanical DOL, setting range 1.8-2.5 A, 0.9 kW at 400 V AC-3, IP65, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"Depth":"190 mm","Width":"120 mm","Height":"270 mm","Maximum":"0.9 kW","Minimum":"0.9 kW","Initial Value":"1.8 A","Type of voltage":"DC","lifecycle_stage":"current","Full-scale value":"2.5 A","Type of assignment":"1","Protection class IP":"IP65","PROFIBUS DP protocol":"No","AS-Interface protocol":"Yes","Design of the product":"direct starter","Type of the motor protection":"bimetal","Design of the switching contact":"electromechanical","Design of short-circuit protection":"circuit-breakers","Product function Bus communication":"Yes","Ambient temperature during operation":"-25 ... +55 °C","Product component Motor brake output":"No","Reference code acc. to DIN EN 61346-2":"Q","Operating power at AC-3 at 400 V rated value":"0.9 kW","Type of electrical connection for main current circuit":"tab terminals","Maximum short-circuit current breaking capacity (Icu) at 400 V rated value":"50 000 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=219075&mlfb=3RK1322-1CS02-0AA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK1322-1CS02-0AA0/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings I need to check for fit?","answer":"The motor rating is 0.9 kW at 400 V AC-3, with an overload setting range of 1.8 to 2.5 A.
