The WKI 35/U is a feed-through terminal block designed for DIN rail mounting with screw-type wire connections. It accommodates fine stranded wire from 16–35 mm² and stranded wire from 16–50 mm² (AWG 10–2), supporting both 400 V/6 kV/3 and 600 V rated voltages. The block features a current carrying capability of 125 A and is constructed with an M5 screw terminal, offering a wire strip length of 51.5 mm and a width of 58 mm. It is suitable for industrial electrical distribution systems, control panels, and power distribution applications where reliable high-current connections are required on standard DIN rail infrastructure.
