The Siemens 3RT1034-1AC20-1AA0-ZX95 is a SIRIUS 3RT1 power contactor rated for AC-3 duty at 32 A, switching 15 kW at 400 V. The 24 V AC coil operates on 50/60 Hz, and the 3-pole Size S2 frame carries screw terminals for upright mounting. The AC-3 rating means it handles the inrush of a squirrel-cage motor during starting and breaking, so it is sized for a 15 kW motor load at 400 V.
Integration notes
Screw terminals accept standard power wiring. The 24 V AC coil draws from a control transformer; verify the VA burden against the transformer rating when multiple contactors share the same supply. The reusable packaging of 30 units suits panel builds.
