The MXS-J236-6 Mechanical Interlock B is a core protective device for industrial electrical safety, designed around the principle of “mandatory interlocking and intrinsic safety” to fully mitigate electrical risks in industrial scenarios. Its precision mechanical interlocking structure strictly adheres to the safety logic of “operation only when powered off”, enforcing standardized operating procedures through physical constraints to fundamentally eliminate hazardous behaviors such as live plugging/unplugging and accidental switching, perfectly meeting the “five prevention” requirements for electrical safety. Constructed with high-impact flame-retardant materials and equipped with multi-layer sealed protection, it achieves IP67 dust and water resistance, capable of stable operation under harsh conditions including a wide temperature range of -25℃ to 70℃, vibrations, and chemical corrosion. Certified by international authorities such as IEC 60309 and CE, it has passed 10,000 cycles of operation testing without failure. Compatible with DIN standard rail for quick installation, it is widely used in critical fields such as smart manufacturing, new energy power stations, and heavy machinery, building an impenetrable protective barrier for equipment and personal safety.
