The coil accepts both AC and DC voltage across 220-240 V, with pickup at 0.8x nominal and dropout at 0.8x at 50 Hz, 0.8-1.1x at 60 Hz. The contactor is rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V on the auxiliary contacts — these are the currents the auxiliary switch can safely interrupt, not the main pole ratings. Power wiring accepts stranded cable from 25 to 120 mm², while the coil and auxiliary terminals take solid or stranded 0.25-2.5 mm² (2x per terminal). Dimensions are 172 mm height, 120 mm width, and 170 mm depth. Mounting is by screw fixing on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back.","metaTitle":"Siemens 3RT1456-2AP36 SIRIUS Contactor, S6 Frame, 220-240V A","metaDescription":"Siemens 3RT1456-2AP36 SIRIUS contactor, size S6, 220-240V AC/DC coil, screw fixing, 170mm depth.
