For resistive loads (AC-12), the maximum operating current is 10 A. Main current circuit connections use screw-type terminals. The solid conductor capacity accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). For stranded conductors, the range is 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), and up to 2x 10 mm². AWG equivalents for main contacts are 2x (16 to 12), 2x (14 to 10), and 1x 8. These ranges cover the vast majority of motor feeder cables up to about 4 mm² per phase — no need for lug adapters on standard runs. This distinction is critical for panel designers deciding whether the contactor must survive a fault without replacement. The contactor occupies a 45 mm width, 85 mm height, and 91 mm depth footprint.","metaTitle":"Siemens 3RT1025-1AV00-0TA0 SIRIUS Power Contactor, S0, 3 NO,","metaDescription":"Siemens SIRIUS 3RT1025-1AV00-0TA0 power contactor, size S0, 3 NO main contacts, 400 V at 50 Hz, 11 kW at 690 V.
