Security Logic Of Ukk Junction Boxes

The electrical and mechanical structure of model din rail power distribution block complies with IEC 60947-7-1, providing verification boundaries for insulation distance, temperature rise, and short-circuit conditions, and specifying conductor cross-sections and rated parameters to ensure consistent measurement and wiring standards for the entire vehicle's power supply system. Model 4 pole distribution block can also utilize DIN NS35 rail mounting and screw connections, ensuring orderly circuit distribution and adaptability to 690V and high-current applications. Some models of model 4 pole power distribution block are equipped with a PA66 housing with a UL94 V-0 flame retardant rating, tinned copper conductors, and a transparent cover for easy visual inspection of crimping conditions and retention of maintenance records.
