Siemens 3RT1054-6AP36 Three-Phase AC Contactor

Siemens Sirius 3RT1054-6AP36 is a three‑pole power contactor designed for AC‑3 duty, suitable for switching motors and other inductive loads in industrial control panels. It is rated for up to 115 A and 55 kW at 400 V (AC, 50–60 Hz), with a coil rated at 220–240 V AC. The device includes auxiliary contacts: 2 normally open and 2 normally closed, providing built‑in feedback and control paths, and it uses screw terminals for main and auxiliary circuit wiring. As part of the SIRIUS 3RT family, it supports reliable motor control up to high power levels in compact, panel‑mounted installations. Typical applications include starting and stopping motors in conveyors, pumps, fans, and machine tools where AC‑3/AC‑3e duty is required, offering a robust solution for integrated control in industrial automation.
