Siemens 3RT1034-1AP00 Contactor

Siemens Sirius 3RT1034-1AP00 is a three-pole power contactor designed for AC-3 duty, capable of switching three normally open main contacts with a main-circuit rating of 32 A. It supports up to 15 kW loads at 400 V and 50 Hz, enabling reliable starting and stopping of 3-phase motors in industrial equipment. The coil is 230 V AC (50 Hz), and the unit uses screw-terminal connections in the compact Size S2 housing for straightforward panel mounting. The contactor features an insulation rating up to 690 V, suitable for standard European power systems. As part of the Sirius 3RT10 family, it is a common choice for motor-control tasks in applications such as pumps, fans, and conveyors, where a robust, compact 3-pole switch is required for safe isolation and control of the motor circuit.
