Weidmüller WTR 2.5 Bloco de terminais seccionador, ligação por parafuso, 2,5 mm², bege escuro

Disconnect terminal block with screw connection technology for reliable circuit isolation and testing in industrial control panels. The WTR 2.5 provides a secure disconnect point for current transformer circuits, enabling safe measurement and maintenance without disturbing permanent wiring.

Advantages

Its Wemid insulation delivers high thermal stability and flame retardance (UL 94 V-0), while the compact 2.5 mm² profile saves valuable DIN rail space. The screw clamp accepts solid, stranded, and ferruled conductors up to 4 mm², ensuring versatile field wiring. A clearly marked disconnect blade allows quick circuit separation, and the dark beige housing blends seamlessly into standard terminal layouts.
