It comes in the compact Size S0 footprint with spring-type terminals and is packaged in multi-unit lots of 6. For procurement, this means the 3RT1026-3FB48-0KS2-ZW98 is no longer in standard production. The official replacement path is the 3RT2 series, which should be evaluated for form, fit, and function compatibility in new designs or BOM revisions. The AC-3 25 A rating at 400 V defines its motor-switching capability: it handles 11 kW induction motor loads in that duty category. The 24 V DC coil means it integrates directly into 24 VDC control circuits common in modern panels, without needing an AC coil supply. ## Panel Integration The Size S0 contactor mounts on a 35 mm DIN rail per EN 50022, with a width of 45 mm and depth of 91 mm. The spring-type terminals accept 0.5–2.5 mm² solid or stranded wire (2x conductors per clamp), with a strip length of 8–10 mm typical for this terminal family.","metaTitle":"Siemens 3RT1026-3FB48-0KS2-ZW98 SIRIUS Power Contactor, AC-3","metaDescription":"Siemens SIRIUS 3RT1026-3FB48-0KS2-ZW98 power contactor, AC-3 25A, 11kW/400V, 24V DC coil, 3-pole, Size S0, spring terminals.
