Main contacts are configured as 10 normally open and 2 normally closed (10...2), and an auxiliary switch is included on the unit. Switching frequency varies by duty class: up to 900 cycles/hour in AC-1 (resistive), 850 in AC-3 (motor starting), 350 in AC-2 (slip-ring motors), and 200 in AC-4 (plugging/inching). ## Mounting and wiring — panel integration notes Dimensions are 70 mm wide, 140 mm high, and 152 mm deep. The 152 mm depth is the dimension to watch when sizing the enclosure depth — it's the deepest axis. Wire range: solid conductors accept 2.5 to 16 mm²; stranded conductors accept 6 to 70 mm². ## Auxiliary contact ratings and arcing characteristics Auxiliary contacts are rated for switching at various control 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, 3 A at 400 V, and 0.8 A at 440 V. These ratings cover standard control circuits in both North American and IEC panels. Arcing time is 10 to 21 ms at AC, with a separate arcing time spec of 10 to 20 ms. Power factor is 0.38 at 50 Hz and 0.8 to 1.1 at 60 Hz — the 60 Hz range is wide because it depends on the connected load's power factor correction.","metaTitle":"Siemens 3RT2047-3AK64-3MA0 SIRIUS Power Contactor, 96 A at 4","metaDescription":"Siemens SIRIUS 3RT2047-3AK64-3MA0 power contactor, Size S3, 96 A rated at 480 V.
