The front face and terminal enclosure are both rated IP20. The S0 footprint (55 mm wide, 85.5 mm tall, 91 mm deep) means it occupies the same slot as other S0 contactors — a direct panel-fit consideration if you're swapping into an existing layout. AC-3 switching frequency is rated at 800 operations per hour maximum; AC-4 drops to 250 per hour. Auxiliary contact reliability is specified for PLC-level signals: 17 V, 5 mA minimum. That means the N.O./N.C. auxiliary block can be read directly by a 24 V DC digital input without wetting-current issues — no need for a separate interface relay on low-power feedback circuits. The AC-3 motor current rating is not directly listed in the available spec set, but the DC-13 and auxiliary switching data give the practical limits for non-motor loads.","metaTitle":"3RT7025-1AB05 Siemens SIRIUS Contactor, S0, 3-pole, 24 V AC","metaDescription":"Siemens 3RT7025-1AB05 SIRIUS contactor, size S0, 3-pole, 24 V AC 50/60 Hz coil, screw terminals, IP20.
