The CJX2-F4004 features a compact and rugged design that can withstand harsh operating conditions, making it ideal for a wide variety of industrial applications. With a maximum voltage rating of 1000V and a current rating of 400A, the contactor can easily handle heavy electrical loads and provide excellent performance. Equipped with advanced technology, CJX2-F4004 has excellent electrical and mechanical durability. Silver alloy contacts ensure minimal voltage drop and reliable conductivity, while double break contacts provide enhanced safety and arc protection. The contactor also adopts a magnetic blow structure, which can effectively extinguish the arc and prevent damage to the contacts. CJX2-F4004 contactors are designed for easy installation and maintenance, with quick connect terminals for easy wiring. Modular design allows easy replacement or addition of auxiliary contacts, timers or other accessories according to your requirements. Safety is paramount when it comes to electrical controls, and the CJX2-F4004 prioritizes safety with its built-in overload and short circuit protection. Thermal and magnetic trip elements continuously monitor the load and immediately disconnect power in the event of an overload or short circuit, preventing any potential damage to equipment and ensuring personnel safety.1.Ambient temperature: -5℃~+40℃; 2.
