That 15.5 A is the real-world limit for plugging or inching a motor; the AC-2 rating of 7.5 kW at 400 V covers slip-ring motor starting, where the current stays lower but the switching frequency is higher. The IP20 front and IP00 terminal protection means it's intended for inside a panel — not washdown, not outdoor without an enclosure. Main circuit terminals accept solid conductors 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²) — or stranded 2x (1...2.5 mm²), 2x (2.5...6 mm²), max 2x 10 mm². AWG equivalents are 2x (16...12), 2x (14...10), 1x 8. That's enough cross-section for the 15.5 A AC-4 rating without overtightening; the screw terminals are the standard box-clamp type, so strip length and torque follow the usual SIRIUS practice.","metaTitle":"Siemens 3RT1025-1AB00-ZW98 SIRIUS Power Contactor, S0, 3 NO,","metaDescription":"Siemens SIRIUS 3RT1025-1AB00-ZW98 power contactor, size S0, 3 NO main contacts, 24 V 50 Hz coil, screw terminals, snap-on DIN rail mount, current lifecycle.
