It's designed for distributed motor control right at the machine, not back in a central panel. Rated for 0.25 kW at 400 V under AC-3 duty (motor starting), with an adjustable setting range of 0.7 to 1.0 A via a bimetal overload relay. That 0.25 kW figure is the same at both minimum and maximum — the part is sized for a specific motor power class, not a wide band. The IP65 enclosure means the entire starter — contacts, overload, bus electronics — is sealed against dust and low-pressure water jets, so it can mount directly on a conveyor frame or machine base in washdown areas without a separate cabinet. ## AS-Interface integration and I/O Communication is via AS-Interface protocol (not PROFIBUS DP), which keeps wiring simple: a single two-wire flat cable carries both power and data to the starter. The unit includes two integrated inputs for local sensors (e.g., limit switches or presence detectors) and a motor brake output rated 24 V DC / 3 A — useful for holding brakes on vertical-axis motors. The 9-pole motor outgoing feeder and 9-pole power connection use tab terminals for the main circuit, so you're looking at fast-on connectors rather than screw terminals — plan your wiring harness accordingly. ## Short-circuit protection and breaking capacity ## Environmental and physical fit Operates from -25 to +55 °C ambient, which covers most factory floor conditions short of a foundry or freezer tunnel.","metaTitle":"Siemens 3RK1322-0JS02-0AA1 AS-i Compact Starter, 0.25 kW, IP","metaDescription":"Siemens SIRIUS AS-i compact direct starter, 0.7-1.0 A setting range, 0.25 kW at 400 V AC-3, IP65, with brake contact and 2 integrated inputs.
