The setting range spans 0.7 to 1 A, using a bimetal overload relay for motor protection. Short-circuit protection is built in via integrated circuit-breakers, and the electromechanical switching contacts handle the reversing function without an external contactor pair. It communicates directly on the AS-Interface network (the protocol is listed as supported), and includes a motor brake output rated at 500 V DC / 1 A, plus two integrated inputs for local sensors or pushbuttons. The main current circuit connects via tab terminals, common for quick-connect field wiring in distributed installations. The setting range of 0.7 to 1 A means the bimetal overload is adjustable within that window; if your motor's full-load current falls outside that band, this starter will not provide proper overload protection. This is a high interrupting rating for a compact starter, typical of the SIRIUS design. Dimensions are 270 mm high, 120 mm wide, and 190 mm deep. The IP65 enclosure means it mounts directly on the machine frame or a wall bracket — no separate panel enclosure needed. ## Integration notes The AS-Interface connection carries both power and communication on the same two-wire yellow flat cable, so no separate control wiring is needed for the network. The two integrated inputs can be used for local start/stop or sensor feedback, reducing the need for a remote I/O block. The brake output (500 V DC / 1 A) is available for holding brakes on vertical-axis motors. Above that, derating may apply — the datasheet should be consulted for thermal performance at the upper end.","metaTitle":"Siemens 3RK1322-0JS02-1AA4 AS-i Compact Starter, 0.25 kW, IP","metaDescription":"Siemens 3RK1322-0JS02-1AA4 AS-i compact reversing starter, 0.7...1 A setting range, AC-3 0.25 kW at 400 V, IP65, with brake contact and integrated inputs.
