The AC-3 rating at 480 V means it handles a 3-phase induction motor drawing up to 96 A under full load, making it a fit for 50 hp class motors in conveyor, pump, and fan applications. The coil holds at 24 VDC nominal; verify the control transformer or PLC output can deliver the inrush without voltage sag. ## Mounting & Wiring — Panel Fit Dimensions: 70 mm wide, 140 mm tall, 195 mm deep — the depth is the key clearance figure when fitting inside a shallow enclosure. Main circuit wiring accepts solid conductors 2.5 to 16 mm² or stranded 6 to 70 mm². Auxiliary contacts are rated for 6 A at 24 V, 2 A at 48/60 V, 0.9 A at 125 V, and 0.3 A at 220 V — check the control voltage before assuming the aux contact can drive the PLC input directly. ## Switching Performance & Environment Arcing time runs 10 to 20 ms, and the contactor can sustain up to 900 operations per hour in AC-1 duty, 850/h in AC-3, and 250/h in AC-4 — the AC-4 figure is the limiting factor for plugging or inching duty. An auxiliary switch is included as standard.","metaTitle":"Siemens 3RT2046-1AV04 SIRIUS Power Contactor, 96 A AC-3, 24","metaDescription":"Siemens SIRIUS 3RT2046-1AV04 power contactor, 96 A AC-3 motor rating, 24 VDC coil, screw terminals, DIN rail mount.
