The MXS-J256-6 Mechanical Interlock B is designed with “intrinsic safety” as the core, serving as a critical barrier for electrical safety in industrial scenarios. Equipped with a mandatory mechanical interlock structure, it strictly follows the safety logic of “plugging/unplugging only when powered off”, fundamentally eliminating risks such as electric sparks, short circuits, and even fires caused by live operations. Featuring a multi-layer sealed protection design, it achieves IP67 dust and water resistance, capable of withstanding dust intrusion and temporary submersion. Combined with a corrosion-resistant and high-strength shell, it can operate stably under harsh working conditions such as high temperatures, vibrations, and chemical corrosion. Compliant with IEC 60309 industrial standards and the fail-safe principle, it automatically switches to a safe state even if an abnormality occurs. Clear “ON/OFF” operation indicators further reduce the probability of misoperation, providing a foolproof safety guarantee for power connections in critical fields such as smart manufacturing, heavy machinery, and new energy power stations.
