Siemens 3RT2025-2FB44-3MA0 Contactor, Spring Terminal Type, AC-3, 7.5kW/400V

Product Positioning

The 3RT2025-2FB44-3MA0 belongs to the Siemens SIRIUS 3RT20 series S00 low-power contactor family. Its AC-3 main circuit is rated at 7.5kW/400V, 17A, and it is more compact than the 3RT2026 series. The "2" in the first segment "-2FB44" corresponds to the spring-loaded (screwless) terminals of the 3RT2025-2XF40-0LA2, allowing for easy clamping without the need for screwdrivers. The difference lies in the addition code "-3MA0" in the latter part of this model, which is a different factory-selected combination than the "-0LA2" of the aforementioned model. Although both have a two-segment coding structure, the actual optional accessories differ. It is recommended to confirm the arrival markings with Kenxin Motor before ordering to avoid confusion with other optional versions.

Core Product Advantages and Features

Spring-loaded (screwless) terminals

The "2" in part number "-2FB44" corresponds to a spring-loaded terminal design. The clamping rod replaces the traditional screw locking, resulting in higher wiring efficiency and reducing the risk of loosening due to long-term vibration.

Exclusive Z add-on code "-3MA0"

Like the 3RT2025-2XF40-0LA2, it is a dual-segment code model, but the optional combinations are different. It is assembled according to this code at the factory. It is recommended to check the specifications of the goods before purchasing.

S00 Low-Power Dedicated Design

The AC-3 7.5kW/400V/17A specification is more compact than the 11kW/25A specification of the 3RT2026 series, making it suitable for small and medium power three-phase motors and avoiding cost waste caused by excessively large specifications.
