The screw-type coil terminals accept solid conductors from 2x (0.5-1.5 mm²) to 2x (0.75-2.5 mm²), while the main power circuit handles stranded cable up to 70 mm². Overall dimensions are 70 mm wide, 140 mm high, 152 mm deep — the 152 mm depth is the dimension to check when planning gland-plate clearance or enclosure depth. ## Operating conditions and auxiliary switch The contactor includes an auxiliary switch and carries a typical mechanical endurance of 10,000,000 operations. Arcing time is 10-20 ms; opening and closing times at both AC and DC are 38-57 ms.","metaTitle":"Siemens 3RT2446-1NP30 SIRIUS Contactor, 175-280V AC/DC Coil,","metaDescription":"Siemens 3RT2446-1NP30 SIRIUS contactor, S3 size, 175-280V AC/DC coil, screw terminals, DIN rail mount.
