Siemens SIRIUS 3RT1456-6NB36 — Size S6 Contactor, AC/DC Coil
The power circuit accepts stranded conductors from 25 mm² up to 120 mm², which covers the heavy end of motor and resistive loads in a panel.
The coil is screw-type terminals and operates on AC or DC from 21 V to 27.3 V. Pickup and dropout timing is symmetrical — 80-90 ms on both AC and DC — so the contactor responds consistently regardless of supply type. At 24 V rated value the auxiliary contacts switch 10 A; at 48 V that drops to 2 A, and at 230 V it handles 6 A. That derating curve matters if you are sharing the auxiliary circuit with a PLC output card or a pilot light string.
Fastened by screw fixing through a single 9 mm hole. The mounting position is flexible: vertical surface with +/-90° rotation or +/-22.5° tilt front-to-back. The body measures 172 mm high, 120 mm wide, 170 mm deep — a standard panel footprint for size S6. Four auxiliary contacts can be attached.
