It is rated for AC-3 duty with a nominal main current of 25 A and a motor load capacity up to 11 kW at 400 V, making it suitable for starting mid-sized three-phase motors. The device mounts on a 35 mm DIN rail with screw or snap-on mounting in accordance with DIN EN 50022, enabling compact panel integration. This specific suffix indicates a 3RT1026-1B..0 unit sold without the surge suppressor accessory 23.002; coil voltage and other electrical characteristics vary by sub-variant within the 3RT1026-1B..0 family, so the exact coil rating should be verified on the official Siemens data sheet for the precise suffix. Commonly used in machine control, conveyors, pumps, and fans where reliable on-board switching and straightforward panel integration are priorities.
