25.780.0453.0 is a feed-through DIN rail terminal block designed for vertical wire-to-PCB connections with 5.00 mm pitch spacing. This component accommodates wire gauges from No. 22 to 12 AWG (0.13 to 2.5 mm² fine stranded or 0.13 to 4 mm² solid), rated for 300 V and 12 A continuous current. The terminal block features a 4-pole configuration with dimensions of 20 mm (G) × 15 mm (T), providing compact integration into DIN rail systems. It is commonly used in industrial control panels, automation equipment, and modular power distribution systems where reliable wire-to-board connections are required in space-constrained environments.
