57.504.0055.2 is a feed-through terminal block with screw connection designed for junction boxes and DIN rail applications. It accommodates fine stranded wire from 0.5–4 mm² or solid wire from 0.5–6 mm² (equivalent to No. 22–10 AWG), with a rated voltage of 800 V (8 kV impulse, 3 kV surge) and 600 V UL/CSA ratings. The block features a width of 6 mm and wire strip length of 9 mm, with a current rating of 32 A at 800 V and 30–35 A at 600 V. This terminal block is compliant with EN 60 947-7-1 and DIN VDE 0611 T1 standards, and is commonly used in electrical distribution systems, control panels, and industrial junction boxes where reliable screw-based wire termination is required.
