56.716.0353.0 is a feed-through terminal block (WKF 16/35PV/WKFN) designed as a supply terminal with spring clamp connection for mounting on DIN rail TS 35. The terminal features a nominal cross section of 16 mm², gray color, and a compact width of 12 mm with 2 clamp positions per level. The insulating housing is constructed from PA66 material with UL94 V0 inflammability classification, ensuring high safety standards. It accommodates wire cross sections ranging from 4 mm² (solid) to 16 mm² (stranded), with a wire strip length of 15 mm, and supports rated currents of 75 A (UL/CSA) and 78 A (CSA). This terminal block is commonly used in industrial control panels, power distribution systems, and electrical installations where reliable feed-through connections and space-efficient mounting are required.
