The MXS-J254-6 Mechanical Interlock B is a high-performance protective device for electrical safety in industrial scenarios, building double safeguards through “physical mandatory interlocking + full-dimensional safety design”. Its core mechanical interlocking structure achieves “unique operational authority” via physical constraints, allowing plugging and unplugging only when fully powered off, fundamentally eliminating fatal risks such as electric arcs and short circuits caused by live operations, reducing accident risks by up to 80%. Crafted with high flame-retardant insulating materials and multi-layer sealing technology, it reaches IP67 dust and water resistance rating, capable of withstanding a wide temperature range of -25℃ to 70℃, 96-hour salt spray corrosion and strong mechanical impact, adapting to harsh industrial working conditions. Fully compliant with IEC 60309 standards and CE certification requirements, it has passed 5000-cycle plug-in durability tests, 850℃ glow wire flame retardancy tests, and electrical performance verification with insulation resistance exceeding 100MΩ. Equipped with clear safety markings and anti-misinsertion structural design, it is widely used in key fields such as machine tools, chemical workshops, and new energy energy storage stations, providing a foolproof power connection protection for stable equipment operation and personnel safety.
