Crimp ferrules Rittal AS 4050.767, copper/PP, 0.75 mm² (length 12 mm, diameter 2.8 mm), pack of 500

Rittal AS 4050.767 crimp ferrules are insulated cable end sleeves designed for reliable termination of 0.75 mm² conductors. Each ferrule combines a copper barrel with a polypropylene (PP) plastic collar that ensures consistent insulation and strain relief. The barrel length is 12 mm and the outer diameter of the insulated collar is 2.8 mm. The product is supplied as a pack of 500 pieces for repeated use in control cabinets, switchgear and industrial wiring.

Advantages

These crimp ferrules provide a solid electrical contact and improved mechanical stability compared with bare conductor terminations. The copper barrel ensures low contact resistance while the PP collar simplifies insertion into terminal blocks and provides additional protection against fraying. Supplied in a bulk pack of 500, they support efficient installation workflows and reduce the need for frequent restocking.

Suitable for (tasks / use cases)

• Termination of stranded copper conductors with a nominal cross-section of 0.75 mm²
• Wiring inside control cabinets and electrical panels
• Switchgear, relays and terminal block connections
• Industrial and machine wiring where vibration-resistant connections are required

When it may not be suitable

These ferrules are intended specifically for conductors of 0.75 mm². They may not provide proper fit or reliable contact with significantly larger or smaller conductor cross-sections. The polypropylene collar and copper barrel are designed for typical industrial terminal blocks; applications requiring special high-temperature insulation or exotic conductor materials may need alternative components.

Key specifications

• Conductor cross-section: 0.75 mm²
• Barrel material: copper
• Insulation material: polypropylene (PP)
• Barrel length: 12 mm
• Insulated collar outer diameter: 2.8 mm
• Pack quantity: 500 pieces

How to use

Strip the conductor to the appropriate length so the bare strands fully enter the copper barrel. Insert the conductor into the ferrule until the insulation meets the PP collar. Use a compatible crimping tool sized for 0.75 mm² ferrules to perform a single, firm crimp at the barrel. After crimping, verify mechanical retention and electrical continuity. Insert the ferrule into the terminal block or connector and secure the clamp or screw according to the terminal manufacturer’s instructions.

What to consider before purchase

• Confirm conductor cross-section is 0.75 mm² for a correct fit
• Ensure your crimping tool supports insulated ferrules of this size
• Check terminal block dimensions to accommodate a 12 mm barrel and 2.8 mm collar
• Buy quantity to match installation volume—pack of 500 provides bulk supply

Usage recommendations

For consistent results, use a calibrated crimping tool matched to ferrules for 0.75 mm² conductors and inspect a sample crimp for proper compression and strand retention before completing large installations.
