The AC-2 rating of 18.5 kW at 400 V covers wound-rotor motor starting. Mechanical life is typical 10,000,000 operations, which sets the maintenance interval for high-cycle lines. The operating temperature range of -25 to +60 °C and storage range of -55 to +80 °C cover most indoor panel environments; pollution degree 3 means it tolerates conductive pollution in industrial atmospheres. The contactor measures 75 mm wide, 112 mm high, and 115 mm deep. It accepts solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (0.75 to 25 mm²) for the main circuit, with a separate terminal rating for solid or stranded 2x (0.75 to 16 mm²). Side-by-side mounting is permitted, which simplifies multi-contactor panel layouts.","metaTitle":"Siemens 3RT1035-3AG16 SIRIUS Power Contactor, Size S2, 18.5","metaDescription":"Siemens 3RT1035-3AG16 SIRIUS power contactor, size S2.
