Side-by-side mounting is permitted, which simplifies multi-contactor panel layouts. Dimensions are 55 mm wide, 129 mm high, and 164 mm deep. ## Terminal and Wiring Capacity The main circuit terminals accept solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (0.75 to 25 mm²) or 2x (0.75 to 16 mm²). This range covers common motor and control wiring sizes used in panel building. Shock resistance is 15g at 5 ms and 8g at 10 ms under AC conditions. Maximum switching frequency varies by duty: 1,200 operations/hour at AC-1 (resistive), 750 at AC-2 (slip-ring motor), 1,000 at AC-3 (squirrel-cage motor), and 250 at AC-4 (plugging/inching). DC dropout delay is 20 to 30 ms. Operating range factor is 0.8 to 1.1 at 50 Hz and 0.85 to 1.1 at 60 Hz. Auxiliary contacts are rated: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. These are the continuous current ratings for the auxiliary circuit.","metaTitle":"Siemens 3RT1034-3EL24 SIRIUS Power Contactor, S2, 24 VDC Coi","metaDescription":"Siemens 3RT1034-3EL24 SIRIUS power contactor, size S2, 24 VDC coil, screw terminals.
