## Summary description

Rittal 4051.791 are light blue ferrules made of polypropylene (PP) for insulated cable termination. Specified for 0.75 mm² conductor cross-section with 8 mm length and 3.4 mm outer diameter, they come in a pack of 500. Designed to ensure reliable, compact wire connections, these ferrules simplify crimping and prevent strand fraying in control cabinets and electrical installations.

## Long description

Rittal 4051.791 light blue polypropylene ferrules are insulated cable end sleeves specified for 0.75 mm² conductor cross-section. Each ferrule measures 8 mm in length with approximately 3.4 mm outer diameter and is manufactured from polypropylene (PP). Supplied as a pack of 500, these ferrules are intended for terminating stranded copper conductors to provide a compact, reliable connection and to prevent strand fraying in control cabinets, terminal blocks and other electrical installations.
Advantages
These light blue ferrules offer consistent insulation and mechanical protection at the conductor end, improving crimp quality and contact reliability. The polypropylene material provides electrical insulation and dimensional stability while keeping the ferrules lightweight. A pack of 500 supports bulk use in panel assembly or on-site wiring jobs, reducing the need for frequent restocking.
Suitable for
 Terminating stranded copper conductors with nominal cross-section 0.75 mm²
 Use with standard ferrule crimping tools designed for insulated end sleeves
 Wiring and assembly in control cabinets, terminal blocks and distribution panels
 Industrial and commercial electrical installations where colour coding (light blue) is used
When it may not be suitable
These ferrules are sized specifically for 0.75 mm² conductors; they are not suitable for larger or smaller conductor cross-sections where a different ferrule size is required. They are made of polypropylene and provide basic insulation; they are not intended for applications requiring high-temperature or chemical-resistant materials.
Key specifications
 Conductor cross-section: 0.75 mm²
 Ferrule length: 8 mm
 Approximate outer diameter: 3.4 mm
 Material: polypropylene (PP) insulation
 Colour: light blue
 Quantity per pack: 500 pieces
How to use
Strip the conductor insulation to the recommended length for the ferrule, insert the stranded conductor fully into the ferrule tube so that strands are contained, and crimp using an appropriate hand or bench ferrule crimper matched to 0.75 mm² ferrules. After crimping, verify a secure mechanical connection and that the insulated sleeve covers the conductor insulation edge. Insert the crimped ferrule into the terminal or block and tighten the terminal screw to the manufacturer’s recommended torque.
What to consider before purchase
 Confirm conductor cross-section is 0.75 mm² to ensure correct fit
 Verify crimping tool compatibility with insulated ferrules of this length and diameter
 Assess whether polypropylene insulation meets temperature and chemical resistance requirements for the intended environment
 Consider colour coding needs — these ferrules are light blue
Usage recommendations
Use a calibrated crimping tool appropriate for 0.75 mm² insulated ferrules and check crimps periodically in series installations. Store packs in a dry environment away from direct sunlight to preserve polypropylene properties.
