AX25-30-10-80 ABB Ac contactor Efficient reliable motor control solutions

The ABB AX25-30-10-80 is a high-performance modular AC contactor belonging to ABB's AX series. It is specially designed for frequent start-stop operations and is suitable for motor control, lighting systems, heating equipment and various industrial automation applications. The AX25-30-10-80 offers outstanding performance and reliability, and is widely used in modern smart factories, building automation and energy management systems. This model supports 3-pole main contacts + no auxiliary contacts, with a rated working current of 25A (AC-3 category) and a coil voltage of DC24V (the model suffix "80" indicates a DC24V control coil). It is an ideal choice for low-voltage distribution and control systems.

Technical Application

Motor control: It is used for the start and stop control of three-phase asynchronous motors such as water pumps, fans, compressors, and conveyor belts.
Building automation: Applicable to central air conditioning systems, elevator control, and management of large lighting circuits.
Industrial production lines: Power switching modules for packaging machinery, injection molding machines, and CNC machine tools.
Energy and Infrastructure: Auxiliary control of photovoltaic inverters, pumping stations of water treatment plants, backup power switching systems.

Installation and Usage instructions

Insert the contactor into the standard 35mm DIN rail and ensure that the snap is fully locked.
Main circuit wiring: L1/L2/L3 is connected to the power supply, and T1/T2/T3 is connected to the load (such as a motor).
Control circuit: A1/A2 is connected to a 24V DC control power supply (note polarity).
It is recommended to connect a thermal overload relay in series in the control circuit to achieve complete motor protection.
