The Siemens SIRIUS 3RT2047-1AB00 is a size S3 power contactor rated for 96 A at 480 V in AC-3 duty, meaning it switches three-phase motor loads up to that current under full load. It mounts on 35 mm DIN rail per DIN EN 60715 via screw and snap-on, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when panel layout forces an odd angle.
The 96 A AC-3 rating at 480 V is the headline number — it governs motor switching for a typical 50 hp (37 kW) 480 V induction motor. The contactor also carries a 900 cycles/hour maximum at AC-1 (resistive load) and 850 cycles/hour at AC-3, so it handles frequent starts on conveyor or pump duty without overheating the coil or main contacts. Coil termination is screw-type, and the auxiliary switch is included as standard. That covers most indoor panel environments, even near ovens or chillers, as long as the panel stays ventilated.
