It combines a bimetal motor protection relay, electromechanical switching contacts, and circuit-breaker-based short-circuit protection into one IP65 enclosure — meaning it lives right at the motor, not in a central panel. The setting range spans 5.5 A to 8 A, and at AC-3 duty (motor starting) on a 400 V line it delivers 3 kW. It communicates over AS-Interface protocol, not PROFIBUS DP, and includes a motor brake output rated 24 V DC / 3 A. The two integrated inputs let you wire limit switches or pushbuttons directly into the starter without a separate I/O block. The main current circuit connects via tab terminals — a fast, tooled connection typical for decentralized motor feeders. This is a decentralized motor starter — it mounts directly on the machine frame or conveyor section, not inside a control cabinet. Dimensions are 270 mm high, 120 mm wide, 190 mm deep — roughly the size of a small junction box. The tab terminals for the main circuit mate with standard 6.3 mm or 9.5 mm receptacles, common on motor cables with pre-terminated leads. The AS-Interface bus cable drops in via the integrated bus communication function, so the only field wiring is the motor cable, the AS-i flat cable, and the 24 V DC supply for the brake.","metaTitle":"Siemens 3RK1322-1HS02-0AA1 AS-i Compact Starter, 5.5-8 A, 3","metaDescription":"Siemens SIRIUS 3RK1322-1HS02-0AA1 AS-Interface compact starter, IP65, DOL motor starting, 5.5-8 A setting range, 3 kW at AC-3/400 V, with brake contact.

That means it is sized for a 3 kW, 400 V three-phase induction motor. The short-circuit breaking capacity (Icu) at 400 V is 50 000 A, which gives selectivity headroom in most industrial distribution."},{"question":"Does this starter include a motor brake output?","answer":"Yes, it has a built-in motor brake output rated 24 V DC / 3 A, so you can control a DC-injected brake directly from the starter without an external contactor."},{"question":"What communication protocol does it use?","answer":"It uses AS-Interface protocol. It does not support PROFIBUS DP.
