Information

Overview Manuals Common Applications Product Precautions

The 3RT6025-1AN20 is a domestically produced industrial control AC contactor from the SIRIUS series manufactured by Siemens. It is mainly used for frequent on/off control of motors or other main circuit loads.

Highly modular
Excellent electrical life
Compact and easy to install

The 3RT6025-1AN20 is a high-performance, compact, and flexibly configured SIRIUS series Size S0 contactor. It excels in switching 7.5 kW (AC-3) loads at 400V, while its 220V AC 50/60Hz wide-frequency coil ensures global power grid compatibility. Featuring integrated 1 NO + 1 NC auxiliary contacts, it perfectly balances the needs for control logic self-holding and electrical interlocking. Combined with robust screw terminal technology and a modular expansion design, it significantly optimizes cabinet space and stands as a core executive component for industrial motor drives and automated load switching, offering exceptional mechanical life and stability.

When using the Siemens 3RT6025-1AN20 contactor, ensure the coil control voltage is stable at 220V AC to prevent coil burnout or poor pull-in caused by voltage fluctuations. During installation, verify that the main terminal connections are tightened to prevent overheating, and cross-check the 7.5kW power limit based on the load type (e.g., AC-3). Additionally, it is recommended to install a surge suppressor on the coil side to protect the upstream PLC controller, and regularly inspect the status of the auxiliary contacts (1 NO + 1 NC) to ensure the reliability of control logic and signal feedback.
