The screw connection technology is adopted, the insulation material is PA66 (flame retardant grade: UL94, V-0), and the connector is made of high-quality and highly conductive metal materials.

H-type through-wall terminal blocks can be installed side by side on panels of 1mm to 10mm thickness, and can automatically compensate and adjust the distance of panel thickness to form a terminal block with any number of poles, and can use isolation plates to increase air gap and creepage distance. The wall-through terminal can be firmly installed in the rectangular reserved hole on the panel without any tools, and the installation is extremely convenient.
