The coil is rated 24 V DC with a holding power of 5.4 W. Front face is IP20; the terminal area is IP00. The 11 kW rating at 400 V AC-3 is the motor-switching capacity — this contactor handles standard squirrel-cage induction motors up to that power during starting and running. At AC-4 (reversing, plugging, inching) the rated current drops to 15.5 A at 400 V, so if your application requires frequent reversing or jogging, size up. The DC coil draws 5.4 W during both closing and holding, which matters for control-transformer sizing and DC supply loading. ## Panel integration — DIN rail, side-by-side, wiring Side-by-side mounting is permitted with 6 mm spacing at the side. Main circuit wiring accepts 2x (1... 2.5 mm²) stranded or 2x (2.5... 6 mm²), max 2x 10 mm². Solid conductors: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), max 2x (0.75... 4 mm²). AWG equivalents for main contacts: 2x (16... 12), 2x (14... 10), 1x 8.","metaTitle":"Siemens 3RT1026-1BB40-ZW98 SIRIUS Power Contactor, 24 V DC C","metaDescription":"Siemens SIRIUS 3RT1026-1BB40-ZW98 power contactor, size S0, 24 V DC coil, rated 11 kW at 400 V AC-3.
