Siemens 3RT2035-1AC20 Three-Phase AC Contactor

Siemens Sirius 3RT2035-1AC20 is a non-reversing, three-pole power contactor designed for AC-3 and AC-3e duty with a 24 V AC coil (50/60 Hz). It is rated for 41 A, equating to about 18.5 kW at 400 V across three phases, making it suitable for starting and running medium-sized motors in industrial panels. The contactor includes one auxiliary contact (1 NO + 1 NC) to drive control circuits or feedback signals, and wiring is carried via screw terminals for robust field connections. Built on the Siemens 3RT Sirius platform, this unit integrates with standard accessories and interlocks used in motor-control applications where compact, reliable three-phase switching at 400 V is required.
