Rated for AC-2 duty at 400 V at 7.5 kW and AC-4 at 400 V at 15.5 A — the AC-2 figure governs motor starting with moderate overload, while AC-4 covers plugging and inching where the contactor makes and breaks stalled-rotor current. For resistive loads (AC-12), it handles 10 A. The 50 Hz coil operates across 0.8 to 1.1 times rated voltage, so a 400 V coil holds in at 320 V and picks up reliably at 440 V. The front face carries IP20 protection; the terminals themselves are rated IP00, so the contactor needs enclosure protection against accidental contact. ## Termination and wiring Main circuit terminals accept solid or stranded conductors: 2x (0.25 to 2.5 mm²) and 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²), with a maximum of 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), or 1x 8.","metaTitle":"Siemens 3RT1025-3AV00 SIRIUS Power Contactor, 3 NO, 45 mm, S","metaDescription":"Siemens SIRIUS 3RT1025-3AV00 power contactor, size S0, 3 NO main contacts, screw terminals, 45 mm width, 90 mm depth.
