AC contactor CJX2-F400 is designed with advanced technology and high-quality components, making it highly durable and suitable for heavy-duty use. With a rated operating current of 400A, the contactor can easily handle large electrical loads, providing a reliable solution for industrial machinery, power distribution systems, and more. One of the main features of the CJX2-F400 is its excellent electrical insulation and arc extinguishing capabilities. The contactors are equipped with high-quality contacts that ensure minimal contact wear, reducing the risk of failure and ensuring a longer service life. Furthermore, its compact design and high resistance to environmental factors make it ideal for installation in a variety of challenging conditions. The CJX2-F400 AC contactor also features enhanced safety features, including built-in overload protection and fault protection. These features not only prevent excessive current or voltage fluctuations, but also protect your electrical system from potential damage or failure, ensuring optimum performance and reliability.1.Ambient temperature: -5℃~+40℃; 2.
