Rated 4 kW at AC-3 duty at 400 V, with an adjustable overload setting range of 7 to 10 A via a bimetal relay, it handles reversing motor loads — conveyors, fans, small pumps — where direction change is part of the cycle. The 7-10 A setting range covers motors drawing roughly 4 kW at 400 V three-phase; the bimetal overload tracks motor heating and trips on sustained overcurrent, protecting the winding from thermal damage. AS-interface protocol carries both control signals and power on a single two-wire flat cable, so the starter receives start/stop and direction commands over the bus without separate control wiring — a wiring reduction that matters on long conveyor lines or skid-mounted cells. A built-in motor brake output rated for 500 V DC / 1 A means the starter can directly drive a DC injection brake on the motor shaft, eliminating a separate brake rectifier or contactor for small reversing applications. The 190 mm depth, 120 mm width, and 270 mm height define the envelope for enclosure or machine-frame mounting; the IP65 housing is self-contained, so no additional panel cutout or DIN-rail is required — the starter mounts directly on the machine frame or a mounting plate. Main circuit connections use tab terminals, which mate with standard 9-pole connectors for motor outgoing feeder and power connection — a pluggable interface that speeds replacement during line-down maintenance. Two integrated inputs allow local pushbuttons or sensors to be wired directly to the starter, supplementing the AS-i bus commands for local override or emergency-stop circuits. The 3RK1322-1JS02-1AA4 is a SIRIUS-series AS-i compact starter; it is not a direct form-fit-function replacement for conventional panel-mount reversing contactors like the 3RT5065-6AB36, which are larger (145 mm wide, 202 mm deep), require screw fixing, and lack the integrated AS-i bus interface and IP65 enclosure.","metaTitle":"Siemens 3RK1322-1JS02-1AA4 AS-i Reversing Starter, 4 kW, 7-1","metaDescription":"Siemens 3RK1322-1JS02-1AA4 AS-i compact reversing starter, IP65, 4 kW AC-3 at 400 V, 7-10 A setting range, bimetal motor protection, 50 kA breaking capacity.
