CTL2.5U/R is a triple-level feed-through terminal block designed for high-density wire-to-wire connections in control, automation, and instrumentation applications. This terminal block features a 6 mm width with dimensions of 67 x 84 mm (height x length), 6 screw clamps with 3 tapped holes for cross connect, and is constructed from Polyamide 6.6 insulation material. It accepts wire ranges of 22-12 AWG (0.5-2.5 sq.mm) with voltage ratings of 300 V (UL) / 500 V (IEC) and current ratings of 25 A (UL) / 24 A (IEC). The red color variant (/R suffix) is ideal for applications requiring color-coded wiring identification, and the terminal block is suitable for DIN rail mounting in space-constrained environments where triple wiring density is required.
