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.","metaTitle":"Siemens 3RT1456-6QF35 SIRIUS Contactor, S6 Frame, 96-127V AC","metaDescription":"Siemens 3RT1456-6QF35 SIRIUS contactor, S6 frame size, 96-127 V AC/DC coil, screw terminals.
