The Siemens 3RT1056-6AF36 is a 3-pole SIRIUS power contactor in frame size S6, designed primarily for switching three-phase motors and other inductive loads in industrial control applications. It provides an AC-3 rated operational current of 185 A and a rated motor power of 90 kW at 400 V. The contactor features a 110-127 V AC/DC coil with conventional drive operation and includes 2 NO + 2 NC integrated auxiliary contacts, reducing wiring complexity in load feeder assemblies. Main circuit terminations are screw-type busbar connections, while the housing is finger-safe per EN 50274 and climate-proof for use in demanding environments. Robust, maintenance-free, and vibration-resistant, the unit forms part of Siemens' modular SIRIUS load feeder system and is widely used in motor starter combinations, pump and fan control panels, and general industrial automation switchgear.
