Cable accessory Rittal 4051.793 polypropylene ferrules 0.75 mm² x 12 mm, light blue (pack of 500)

Rittal 4051.793 polypropylene ferrules are crimp end sleeves designed for reliable termination of 0.75 mm² conductors. Each ferrule is 12 mm long with an outer diameter of 3.4 mm and is produced from polypropylene (PP) in a light blue colour. Supplied in a pack of 500, these ferrules provide consistent, insulated ends for stranded wires used in electrical panels, control cabinets and wiring harnesses.

Advantages

These Rittal ferrules provide a uniform insulation collar and conductor sleeve that aid in consistent crimping quality and stable electrical connections. The polypropylene construction offers dimensional stability and electrical insulation while keeping the product lightweight. Colour coding in light blue helps with visual identification and conformity to KDS colour coding practices. A bulk pack of 500 supports efficient installation and reduces the need for frequent replenishment on site.

Suitable for

• Termination of stranded copper conductors with a nominal cross-section of 0.75 mm²
• Use in control cabinets, distribution panels and terminal blocks
• Industrial and commercial electrical wiring harness assembly
• Applications requiring colour-coded, insulated ferrules for organised wiring

When it may not be suitable

These ferrules are intended specifically for 0.75 mm² conductors; they will not provide a correct fit or reliable termination for significantly larger or smaller conductor sizes. They are made of polypropylene and are intended for standard electrical insulation and mechanical support; they are not designed for high-temperature environments or applications requiring metallised insulation sleeves or additional environmental sealing.

Key specifications

• Material: polypropylene (PP) insulation with metal conductor sleeve
• Nominal conductor cross-section: 0.75 mm²
• Length: 12 mm
• Outer diameter: 3.4 mm
• Colour: light blue
• Pack quantity: 500 pieces

How to use

Strip the conductor to the recommended insulation length, insert the stranded wire into the ferrule until the conductor sleeve is fully seated, and crimp using a suitable ferrule crimping tool sized for 0.75 mm² ferrules. After crimping, inspect the connection for a secure mechanical hold and correct insulation positioning. Insert the crimped ferrule into the terminal or connector and tighten the terminal screw to the manufacturer’s specified torque for the terminal block or device.

What to consider before purchase

• Confirm conductor cross-section is 0.75 mm² for correct fit
• Verify the required ferrule length (12 mm) and outer diameter (3.4 mm) match your terminal requirements
• Consider whether polypropylene insulation and light blue colour meet any site coding or temperature requirements

Usage recommendations

Use a dedicated crimping tool calibrated for insulated ferrules to ensure consistent crimps. Store the bulk pack in a dry environment away from direct sunlight to preserve polypropylene properties. For electrical panels, maintain consistent colour-coding and document terminal assignments to aid maintenance and troubleshooting.
