WAGO 216-205 ferrules are essential accessories for WAGO terminal blocks, providing a secure and reliable connection between wires and the terminal. Constructed from electrolytic copper and insulated, these ferrules are designed for wire sizes of 2.08 mm² / AWG 14. They minimize contact resistance and prevent corrosion, ensuring long-term performance in industrial applications such as power distribution, automation, and control systems. The yellow color provides easy identification and organization within electrical panels.
