Cable accessory Rittal 4051.792 light blue polypropylene ferrules 0.75 mm² x 10 mm, pack of 500

Rittal 4051.792 light blue polypropylene ferrules are crimpable end sleeves designed for insulated conductor terminations. Each ferrule is sized for 0.75 mm² conductors, with a 10 mm sleeve length and an approximate outer diameter of 3.4 mm. Supplied in a pack of 500, these ferrules are intended for use in control cabinets, distribution panels and general wiring work where secure, insulated terminations are required.

Advantages

These polypropylene ferrules offer consistent mechanical protection of stranded conductors and help prevent fraying when inserting wires into terminal blocks or screw connectors. The light blue colour follows a common colour-coding scheme for easy identification of conductor cross-section during installation and maintenance. Supplied in a bulk pack of 500, they are convenient for repetitive wiring tasks and reduce handling time compared with single-use packaging.

Suitable for

• Terminating stranded copper conductors with cross-section 0.75 mm²
• Industrial control cabinets and electrical distribution panels
• Terminal block and screw connector applications
• Batch wiring tasks and professional electrical assemblies

When it may not be suitable

These ferrules are specifically sized for 0.75 mm² conductors; they are not suitable for larger or smaller cross-sections. They are designed for insulated wire terminations and are not intended as a substitute for crimp connectors that provide additional environmental sealing or higher current ratings.

Key specifications

• Material: polypropylene (PP)
• Conductor cross-section compatibility: 0.75 mm²
• Sleeve length: 10 mm
• Approximate outer diameter: 3.4 mm
• Colour: light blue
• Quantity: 500 pieces per pack

How to use

Strip the conductor to the appropriate length so that the exposed strands fit completely inside the ferrule sleeve. Insert the stranded conductor into the ferrule until the insulation meets the sleeve end, then crimp with a suitable insulated ferrule crimping tool sized for 0.75 mm² ferrules. After crimping, check that the sleeve is securely compressed and that there is no loose strand protruding. Insert the ferrule-terminated conductor into the intended terminal or connector and tighten the terminal screw to the manufacturer's specified torque.

What to consider before purchase

• Confirm conductor cross-section is 0.75 mm² to ensure correct fit
• Verify required sleeve length and outer diameter match installation space
• Ensure a compatible crimping tool is available for insulated ferrules
• Consider colour-coding requirements for your wiring standard

Usage recommendations

Use a dedicated insulated ferrule crimping tool and follow terminal torque specifications to achieve reliable electrical and mechanical connections. Store the pack in a dry environment to preserve polypropylene properties.
