Siemens 3RT2035-1AK64-3MA0 SIRIUS 3RT2 Power Contactor, S2, 41A, 18.5 kW, 3-Pole, 110/120V AC Coil, Screw Terminal Original Brand New

Overview

The Siemens SIRIUS 3RT2035-1AK64-3MA0 power contactor is a high-performance switching device designed for reliable control of motors and resistive loads up to 18.5 kW at 400V (AC-3e/AC-3). Part of the trusted SIRIUS 3RT2 series, this robust Size S2 contactor is engineered for demanding industrial applications.

It features a high operational current of 41 A and a versatile control coil voltage of 110 V AC (50 Hz) / 120 V AC (60 Hz). The contactor is equipped with a secure screw terminal connection and an integrated, captive auxiliary switch block (2 NO + 2 NC) for essential interlocking and signaling functions.

Function

The 3RT2035-1AK64-3MA0 contactor serves as an electromagnetically operated switch, primarily used to safely and remotely control and switch on/off three-phase asynchronous motors and other high-current electrical loads. When the 110/120V AC coil is energized, the three main power contacts close, connecting the load to the power supply. The integrated 2 NO + 2 NC auxiliary contacts provide immediate feedback on the contactor’s status to the control system (e.g., PLC, relays) or can be used for self-latching and safety interlocks.
