AC-3 motor switching at 22 kW
The Siemens 3RT1036-1AP04-ZW95 is a 3-pole contactor from the SIRIUS series, rated for AC-3 duty at 22 kW at 400 V. That AC-3 rating means it's designed for switching squirrel-cage motors — starting, stopping, and jogging under load — not just resistive heating elements. The 230 V AC 50 Hz coil pulls in cleanly at nominal line voltage; verify the control transformer secondary is sized for the inrush if you're driving it from a PLC output card through an interposing relay.
