The AC-3 motor-switching rating governs the real-world load: this contactor handles induction motors up to the current limit defined by the motor's locked-rotor and running duty cycle. For DC-13 solenoid loads at 220 V, the rated operational current is 0.3 A — relevant for brake coils or holding magnets in the same panel. ## Environmental and protection class IP20 on the front and at the terminals — finger-safe against accidental contact but not sealed against moisture or dust ingress. Operating temperature range -10 to +55 °C; storage range -25 to +70 °C. ## Wiring and auxiliary options Main and auxiliary/control circuits use screw-type terminals. Accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or finely stranded wire with core-end processing. The product accepts auxiliary switch add-ons (product extension auxiliary switch: Yes), so a side-mount block can be fitted for feedback or status indication without replacing the contactor. ## Short-circuit protection coordination For type 1 coordination, the maximum fuse rating is 63 A gL/gG NH 3NA. For type 2 coordination (where the contactor must remain operational after a fault), the fuse limit drops to 25 A gL/gG NH 3NA. This distinction matters when selecting upstream protection for a motor branch circuit that must survive a short-circuit event without contactor replacement.","metaTitle":"Siemens 3RT7025-1AM05 Contactor, S0 Size, 3-Pole, 690 V, AC-","metaDescription":"Siemens 3RT7025-1AM05 SIRIUS contactor, size S0, 3-pole, 690 V rated insulation voltage, AC-3 duty, 55 mm wide.
