AX18-30-10-81 ABB Ac contactor Compact and reliable DC control Optimized medium small sized loads
ABB AX18-30-10-81 is a high-performance modular AC contactor belonging to the ABB AX series. It is specially designed for frequent start-stop operations and is suitable for the control of small and medium-sized three-phase asynchronous motors, lighting systems and other AC-3 or AC-1 type loads. This model supports 3-pole main contacts + no auxiliary contacts, with a rated working current of 18A (AC-3 category) and a coil voltage of AC24V (the model suffix "81" indicates AC24V control coil). It is an ideal choice for low-voltage distribution and control systems.
Key features
High reliability and long service life
It can withstand up to one million operation cycles under the AC-3 usage category.
The mechanical life exceeds 15 million cycles, meeting the demands of various harsh environments.
Energy conservation and environmental protection
It adopts low-power electronic holding coil technology, which is energy-saving and highly efficient.
Low standby power consumption, in compliance with international standards such as IEC 60947-4-1 and RoHS/REACH regulations.
Modular design, flexible expansion
It can be assembled with various accessories: auxiliary contact modules, surge suppressors, mechanical interlock devices, etc.
