The headline rating of 10 A at AC-12 (resistive load) defines its maximum continuous current for general-purpose switching. For motor duty, the AC-2 rating at 400 V delivers 11 kW — this is the figure that governs fit for most three-phase induction motors in that power band. The AC-4 rating of 15.5 A at 400 V covers reversing or inching service where the contactor makes and breaks stalled-rotor current. The operating temperature range of -25 to +60 °C and pollution degree 3 rating mean this contactor is suited for industrial environments with conductive dust or occasional condensation — typical in unheated plant floors or refrigeration machinery rooms. The IP20 front protection keeps fingers away from live terminals inside the enclosure; the terminal itself is IP00, so it must be housed in a panel. The S0 footprint — 45 mm wide, 85 mm tall, 140 mm deep — fits standard panel layouts. The auxiliary contact block (2 instantaneous contacts) can be added on the front. This lets the panel designer balance protection level with fuse availability.","metaTitle":"Siemens SIRIUS 3RT1026-1AC24-0AA1-ZW97 Power Contactor, S0,","metaDescription":"Siemens SIRIUS power contactor 3RT1026-1AC24-0AA1-ZW97, S0 size, 24V 50/60Hz coil, 10A AC-12, 11kW AC-2/AC-3 at 400V.
