Quadrios 22C430 Puntalino 4 mm² parzialmente isolato grigio 100 pezzi

Wire end sleeve for reliable termination of fine-stranded conductors with 4 mm² cross-section. The tin-plated electrolytic copper sleeve ensures low contact resistance and corrosion protection, while the grey polypropylene collar provides strain relief and prevents strand breakage during installation.

Advantages

Partially insulated design allows visual inspection of the conductor insertion depth. The tin plating enhances solderability and protects against oxidation. The polypropylene insulation offers good chemical resistance and maintains its shape at elevated temperatures.

Suitable for

• Control cabinet wiring
• Terminal blocks and screw connections
• Industrial machinery and automation systems
• Electrical installations requiring DIN 46228 Part 4 compliant ferrules
