Motor switching and coil constraints
The 3RT2036-1AP00-Z W96 is a SIRIUS 3RT2 power contactor rated for AC-3e/AC-3 duty at 51 A, switching 22 kW at 400 V three-phase. That AC-3 rating governs motor starting and running — the contactor is sized for a 22 kW induction motor on a 400 V line, so it handles locked-rotor inrush and breaks the load current without welding the main poles. The coil pulls 230 V AC at 50 Hz; verify your control transformer matches that voltage and frequency before wiring. Auxiliary contacts are 1 NO + 1 NC, screw-terminated, which gives you one feedback signal and one interlock for the control circuit. Frame size S2 means the contactor occupies a defined DIN-rail footprint — check your panel layout for the 122.5 x 62 x 142 mm envelope before committing the backplate.
