Siemens 3RT1024-1AP04 General Purpose Contactor

Siemens Sirius 3RT1024-1AP04 General Purpose Contactor is a three‑pole AC‑3 contactor designed for motor control and general load switching in industrial environments. It provides three normally open main contacts and an auxiliary block with two normally closed and two normally open contacts for control circuits, interlocking, and feedback signals. The coil operates at 230 V AC, enabling direct interfacing with standard plant control electronics without an external transformer. In AC‑3 service at 400 V, this model is rated for up to 5.5 kW, aligning with common motor starting tasks for small to mid‑size motors used in conveyors, pumps, and machine tools. The compact Sirius package integrates the auxiliary contacts with the main circuit to simplify wiring and control logic, while maintaining compatibility with typical control schematics and accessory blocks across the Sirius line. Suitable for panel mounting in industrial control panels, the 3RT1024‑1AP04 supports reliable switching of loads and straightforward integration into existing motor control or sequencing circuits.
