3RT2025-1KB40

The 3RT2025-1KB40 is a standard contactor in the SIRIUS 3RT2 series S00 chassis, featuring a 24V DC coil and traditional screw terminals. The main circuit can handle up to 17A AC-3 current, maintaining the 7.5kW (400V) motor starting and stopping capability consistent with the 3RT2025 family. The auxiliary contacts are 1NO + 1NC, providing basic operating status feedback. Compared to spring-terminal models, screw terminals are more suitable for the work habits of experienced technicians and facilitate regular checks of the locking condition using standard screwdrivers and torque tools. This makes it a common choice for modifying existing panels or replacing spare parts. The unit weighs approximately 0.588kg and can be directly mounted on a DIN rail, with installation methods consistent with other screw-terminal models in the same series, allowing for easy mixing and matching with models such as the 3RT2025-1AP00 and 1AR60.
