Additional Technical Features
● Product Characteristics: The entire AX series complies with standards such as IEC 60947-4-1, featuring a rated insulation voltage (Ui) of up to 1000V and a rated impulse withstand voltage (Uimp) of 8kV. Without a thermal overload relay installed, the operating ambient temperature range is -40°C to +70°C, and the devices can operate at altitudes up to 3000 meters without derating.
● Accessories and Installation: The series supports a wide range of accessories, such as auxiliary contacts, mechanical interlock units, and timers. High-current contactors (AX185–AX370) feature zero arcing distance, allowing for installation directly against the cabinet door to save space.
