The Siemens SIRIUS 3RT1456-6QF35 is an S6 frame contactor with a 96-127 V AC/DC coil — a common control voltage that simplifies integration across both AC and DC control circuits without separate coil selection. The coil termination uses screw-type terminals, and the main power circuit accepts stranded conductors from 25 mm² up to 120 mm², sized for the S6 frame's current-handling capacity. Mechanical endurance is rated at 10 million operating cycles, which aligns with the SIRIUS series' typical life for high-cycling conveyor, pump, or compressor applications.
Auxiliary contact performance
The contactor includes an auxiliary switch. Rated currents at various control voltages: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, and 0.9 A at 125 V — all at the respective rated values. These figures govern the auxiliary contact's ability to switch pilot devices, PLC inputs, or indicator lamps at the given voltage levels.
