Inrush peaks at 1.5 A; steady-state draw is 2 VA at 50 or 60 Hz. ## Switching performance and contact ratings Switching frequency varies by duty: up to 1,200 ops/hr in AC-1, 1,000 in AC-3, 750 in AC-2, and 300 in AC-4. Arcing time is 10–20 ms; operate time is 30–55 ms for both AC and DC coils. Auxiliary contact ratings are provided for DC loads: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. No auxiliary switch block is included as standard. Dimensions are 55 mm wide, 114 mm high, and 174 mm deep. Wire capacity for main contacts is 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²) solid or stranded.","metaTitle":"Siemens 3RT2035-1NF34 SIRIUS Power Contactor, Size S2, 83-15","metaDescription":"Siemens 3RT2035-1NF34 SIRIUS power contactor, Size S2, 83-155V AC/DC coil, screw terminals, DIN rail mount.
