Product Positioning

The 3RT2025-2KF40 is a single-segment code model in the SIRIUS 3RT20 series S00 low-power contactor family. The ordering code is simply "-2KF40", unlike the 3RT2025-2XF40-0LA2 or 3RT2025-2FB44-3MA0 which include an additional "Z" add-on code. This makes it a relatively simple and standardized ordering model, facilitating sales quotations and parts management. The first code "2" corresponds to a spring-loaded (screwless) terminal; the clamping rod completes the wire clamping. The main circuit maintains the family specification of AC-3 7.5kW/400V, 17A, suitable for start-stop control of small to medium power three-phase motors. Compared to the 3RT2025-2KC80 and 3RT2025-2KB40, which are also in the K-code family, this model ends with "F40". Please refer to the packaging markings or contact sales for confirmation regarding the actual coil voltage and auxiliary contact configuration.

Core Product Advantages and Features
Spring-loaded (screwless) terminals
The "2" in part number "-2KF40" corresponds to a spring-loaded terminal design, where the clamping rod replaces the screw for fastening, making it suitable for rapid installation in production line environments with a large number of wires.
Single-segment standard order code
Without an additional Z add-on code, the part number structure is simpler, making it easier to compare prices and prepare in-stock materials compared to the dual-segment codes -0LA2 and -3MA0.
Belonging to the K-code family
Like 3RT2025-2KC80 and 3RT2025-2KB40, it is a model with the code "K" at the beginning, and the last code "F40" is the distinguishing code for this model.
