Siemens 3RT2526-1AK60 is a four-pole power contactor designed for AC-3 duty, rated to switch 25 A and up to 11 kW at 400 V. It is driven by a 110 V AC control coil compatible with 50 Hz and 60 Hz supplies. The device provides four main contacts: two normally open and two normally closed, complemented by an auxiliary contact block featuring one normally open and one normally closed contact. Terminals are screw-type for straightforward wiring, and the unit is sized as S0 within the Siemens 3RT25 family. With its combination of high-capacity power contacts, a dedicated control coil, and integrated auxiliary contacts, this contactor is well suited for starting and stopping three-phase motors and other AC loads in industrial automation where compact, versatile motor control is required.
