Non-insulated ferrules serve a specific purpose where the insulation collar of a standard ferrule would be a hindrance. The QUADRIOS 22C477 is designed for use in double-level or multi-tier terminal blocks where the clearance between layers is minimal. Without the collar, the ferrule can be inserted deeper into the terminal body, allowing the screw clamp to make direct contact with the conductive barrel.

This ferrule is manufactured from high-purity copper to ensure excellent conductivity and then coated with tin to provide corrosion resistance and improve solderability. The single-barrel design is intended for terminating a single 2.5 mm² conductor. It is critical to note that this ferrule does not provide any finger-safe insulation; the terminal block itself must provide adequate protection against accidental contact.

Use this ferrule when you need to save space in high-density wiring applications or when the terminal block’s design requires a collarless termination. Ensure your crimping tool is set up for non-insulated ferrules of this gauge to achieve a secure crimp.
