The coil accepts 50/60 Hz at a rated voltage of 230 V (50 Hz) or 230 V (60 Hz). The S0 frame measures 65 mm wide by 85 mm tall by 91 mm deep — a standard footprint for this class. Terminals accept 2x (0.25... 2.5 mm²) solid or stranded, up to 2x 10 mm², or 2x (16... 12) AWG. ## Duty ratings and coordination AC-4 at 400 V is 15.5 A, for plugging or inching duty. For type 2 coordination (no weld risk) use a 35 A gL/gG fuse; type 1 coordination allows a 100 A fuse. Auxiliary contacts: 2 normally open instantaneous contacts rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V. The SIRIUS series carries IEC and UL certifications as standard. The contactor is rated for pollution degree 3, altitude up to 2 000 m, and operating ambient -25 to +60 °C.","metaTitle":"Siemens 3RT1026-3AL26 SIRIUS Power Contactor, 11 kW AC-2 at","metaDescription":"Siemens SIRIUS 3RT1026-3AL26 power contactor, S0 frame, 11 kW at 400 V AC-2, 15.5 A AC-4, 50/60 Hz, screw terminals, current production.
