WAGO 2002-403 2-Conductor Through Terminal Block, 2.5 mm², 25 A, 800 V, Gray

The WAGO 2002-403 is a compact 2-conductor through terminal block from the 2002 Series, designed for reliable and maintenance-free wiring in industrial and building installations. With a rated current of 25 A and rated voltage of 800 V, it accommodates solid and fine-stranded conductors from 0.25 to 4 mm² (AWG 22–12). The CAGE CLAMP® connection technology ensures fast, vibration-proof, and gas-tight connections without the need for tools. The gray polyamide housing offers high mechanical strength and a flammability rating of UL94 V0, making it suitable for demanding environments.
