The bus communication function is built in, so it connects directly to an AS-i network without an extra gateway module. The 9-pole motor outgoing feeder and 9-pole power connection carry the motor cable and the AS-i bus in one harness, which keeps the field wiring tidy. A motor brake output is integrated, rated at 500 V DC / 1 A, so you can control the holding brake on a vertical-axis motor directly from the starter without a separate contactor.","metaTitle":"Siemens 3RK1322-1ES02-1AA4 AS-i Compact Reversing Starter, 2","metaDescription":"Siemens SIRIUS 3RK1322-1ES02-1AA4 AS-i compact reversing starter, IP65, 2.8-4 A setting range, 1.5 kW AC-3 at 400 V, 50 kA SCCR.
