Rittal 4050757 Terminal Isolado 0,34 mm² Turquesa 500 Unid.

Terminating fine-stranded conductors in control cabinets and industrial wiring often leads to splayed strands, poor contact, and unreliable screw or spring clamp connections. Rittal 4050757 insulated wire end ferrules solve this by providing a gas-tight, mechanically stable crimp that protects the conductor and ensures a durable, vibration-resistant connection.

Who is it for

Electrical installers, panel builders, and maintenance technicians working with fine-stranded copper conductors in automation, switchgear, and control systems. Suitable for professionals who require consistent, high-quality terminations in accordance with DIN 46228 Part 4.

Tips

Use a crimping tool with a suitable die profile for insulated ferrules to achieve a reliable crimp. Ensure the stripped conductor length matches the metal ferrule length so that the insulation collar is not crimped. Store ferrules in a dry environment to prevent oxidation of the tin plating.
