The Siemens SIRIUS 3RT1025-1AR60-ZX95 is a size S0 power contactor rated for motor switching up to 11 kW at 690 V (AC-3, 50 Hz) and 10 kW at 500 V. At 24 V DC the coil draws 10 A.
The AC-3 motor rating of 11 kW at 690 V tells you this contactor handles a 3-phase induction motor of that power at that voltage in a standard starting/running duty cycle. For resistive loads (AC-1) the maximum operating current is 10 A. The IP20 front protection keeps fingers out; the terminals themselves are IP00, so the panel enclosure provides the environmental seal.
The 45 mm width and 85 mm height fit the S0 footprint; depth is 91 mm. Screw terminals on the main circuit accept 2x (1.0 to 2.5 mm²) solid or stranded, with a maximum of 2x 10 mm². The auxiliary circuit terminals take 2x (0.5 to 1.5 mm²) solid.
Short-circuit coordination
For Type 1 coordination (contactor may need replacement but the circuit is cleared) the fuse can be gL/gG 63 A. This matters when you're specifying the motor branch circuit — the fuse size determines whether the contactor survives a short-circuit event.
