It's rated for motor switching up to 11 kW at 690 V AC-3 or 10 kW at 500 V AC-3, which covers most three-phase induction motors in that power band. The AC-3 rating of 11 kW at 690 V is the motor-switching figure that matters for sizing: it covers starting and running of squirrel-cage motors up to that load. For resistive loads (AC-1), the contactor can handle the full thermal current of the frame, but the evidence doesn't list a separate AC-1 current; the AC-12 rating of 10 A maximum gives a floor for control-circuit switching. DC switching capability is limited but present: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. These are resistive DC ratings — inductive DC loads (brakes, clutches) need derating or a free-wheel diode. Short-circuit coordination is specified: Type 1 coordination requires a 63 A gL/gG fuse, Type 2 requires a 25 A gL/gG fuse. Type 2 is the standard for most industrial panels — after a fault the contactor remains usable.","metaTitle":"Siemens 3RT1025-1AC20-ZX95 SIRIUS Power Contactor, 11 kW at","metaDescription":"Siemens 3RT1025-1AC20-ZX95 SIRIUS Size S0 power contactor, 24 VAC coil, 11 kW at 690 V AC-3.
