It switches loads up to 690 V in AC-3 and AC-3e duty, which covers squirrel-cage motor starting and stopping under full load — the rating that governs real motor branch circuits. The screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid or 2x (0.75...2.5 mm²) finely stranded with ferrule, matching typical panel-wiring practice for this frame class. ## Coil draw and thermal limits The DC magnet coil draws 0.72 W on closing and holds at 0.24 W — low enough that multiple contactors on a single 24 VDC supply don't overwhelm the power budget. Operating temperature range is -10 to +55 °C, storage from -25 to +70 °C. Shock resistance is 12.5g at 5 ms and 7.8g at 10 ms sine pulse on AC — relevant for machine-tool or conveyor applications where vibration is present. ## Coordination and auxiliary options The contactor accepts auxiliary switch add-ons, so you can field-fit a mirror contact or early-make/early-break block without changing the base unit. Maximum switching frequency is 800 operations per hour in AC-3/AC-3e duty, and 250 ops/h in AC-4 (plugging/inching). The 6 kV surge voltage resistance (rated impulse withstand) means it's suitable for installations requiring basic overvoltage category III coordination.","metaTitle":"Siemens 3RT7025-1AN25 Contactor, S0 Frame, 3-Pole, 690 V AC-","metaDescription":"Siemens 3RT7025-1AN25 Size S0 contactor, 3-pole, 690 V AC-3/AC-3e max.
