Product details

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.

Auxiliary contact performance

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.

As an active-production SIRIUS contactor, the 3RT1456-6QF35 is sourced through our independent distribution channels.

Frequently asked questions

What is 3RT1456-6QF35's listed depth (170 mm) on this component line?

The depth is 170 mm, with a height of 172 mm and a width of 140 mm. These dimensions define the panel cutout and enclosure space required.

What is 3RT1456-6QF35's listed solid (2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), max. 2x (0.75... 4 mm²)) on this component line?

Those solid conductor sizes apply to the auxiliary and control wiring terminals, not the main power circuit. The main power terminals accept stranded conductors from 25 to 120 mm².

Will 3RT1456-6QF35 drop into a panel that was specified around 3RT1055-6QF35 without rewiring?

No. The 3RT1456-6QF35 is an S6 frame with a 172 x 140 x 170 mm footprint, while the 3RT1055-6QF35 is a smaller frame. The mounting hole pattern, terminal positions, and clearance requirements differ. Panel rework and rewiring would be required.
