Size S6 is the mechanical frame that determines the contactor's thermal and dynamic current capacity. For a panel-builder, this means the 3RT1456-6AR36 occupies a defined footprint and requires specific clearance: 10 mm upwards, 20 mm forwards, 10 mm downwards, and 10 mm at the side — plan your enclosure layout accordingly. The contactor carries a built-in auxiliary switch with four contacts. Each auxiliary contact is rated for specific voltages: 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 ratings define the maximum switching current for control-circuit loads like PLC inputs, relay coils, or indicator lamps at each voltage level. Coil terminals are screw-type, accepting solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or max 2x 0.75 to 4 mm². Power-side terminals accept stranded conductors from 25 to 120 mm². This covers standard control wiring up to 4 mm² and motor power cables up to 120 mm². Because it is an active, catalog-listed part, sourcing is straightforward: provide the exact order code and quantity, and the supply chain can confirm lead time and pricing against your delivery window. No broker or surplus channel is needed.","metaTitle":"Siemens 3RT1456-6AR36 SIRIUS Contactor, Size S6, 440-480V AC","metaDescription":"Siemens SIRIUS 3RT1456-6AR36 contactor, Size S6, 172x120x170 mm.
