It carries three normally-open main contacts and zero normally-closed main contacts, so it is a straight motor-starting contactor — not a reversing or star-delta configuration out of the box. The coil is rated for 24 V at 50 Hz, drawing 0.8 to 1.1 A inrush; the operating range spans -25 to +60 °C, with pollution degree 3 for industrial environments. Front protection is IP20 for operator safety; the terminal area is IP00, meaning the wiring compartment must be inside an enclosure or guarded during operation. ## Motor Ratings and Coordination Rated motor power at 400 V is 11 kW in AC-2 duty and 11 kW at 500 V and 690 V in AC-3, so it covers standard 400 V and 690 V industrial supply systems with the same switching capability. For AC-4 reversing or inching duty, the rated operational current is 15.5 A at 400 V — significantly lower than the AC-3 motor rating, as expected for high-stress switching. Type 1 coordination allows up to 100 A gL/gG — important for selectivity studies in the panel design. The closest functional peer in the SIRIUS family is the 3RT1036-1AB00, which shares the S0 frame and 3 NO main contact arrangement but differs in coil voltage and auxiliary contact configuration; verify coil compatibility before substituting.","metaTitle":"Siemens 3RT1026-3AB00-ZX95 SIRIUS Power Contactor, S0, 3 NO,","metaDescription":"Siemens SIRIUS 3RT1026-3AB00-ZX95 power contactor, size S0, 3 NO main contacts, 11 kW at 690 V AC-3.
