YASKAWA ELECTRIC HI-25ET AC magnetic contactor HI25ET

Description:

The Yaskawa HI-25ET is an AC magnetic contactor designed for switching electrical loads in industrial control systems such as CNC machines and automation equipment. It features a 3-pole configuration and operates using an electromagnetic coil (typically 220–230V AC) to open and close the main contacts. This allows reliable remote switching of motors, pumps, and other electrical loads. The unit is part of Yaskawa’s legacy HI series and is now discontinued but still widely used in maintenance and retrofit applications.

Applications:

The Yaskawa HI-25ET contactor is commonly used in CNC machines (including Mori Seiki), motor control panels, and industrial automation systems. It is typically applied in switching circuits for motors, coolant systems, and auxiliary equipment where consistent and durable electrical control is required. Today, it is primarily used for replacement in existing installations rather than new systems.
