The envelope is 172 mm high, 120 mm wide, and 170 mm deep, which places it in the larger end of the SIRIUS contactor range. Main power terminals accept stranded conductors from 25 to 120 mm², which covers the range you'd expect for a Size S6 contactor handling higher-current motor circuits. The auxiliary/signal terminals are screw-type and accept solid or stranded wire in multiple combinations: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²), with a maximum of 2x (0.75 to 4 mm²). That's enough for daisy-chaining control wiring or paralleling auxiliary contacts without a separate terminal block. The coil terminals are also screw-type, so no special crimp tooling is needed for the control circuit. ## Switching performance and ratings Auxiliary contact switching capacity is specified at several voltage levels: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 6 A at 230 V. These are the make/break ratings for the built-in auxiliary contacts — useful when you're feeding PLC inputs or pilot lights at different control voltages. The 10 A at 24 V is generous for a built-in auxiliary; it can drive multiple relay coils or indicator loads directly.","metaTitle":"Siemens 3RT1456-6AT36 SIRIUS Contactor, Size S6, 575-600V AC","metaDescription":"Siemens 3RT1456-6AT36 SIRIUS contactor, size S6, rated 575-600V AC/DC.
