Cable ferrules Rittal 4051.719, polypropylene light blue, 0.75 mm², 12 mm, pack of 500

Rittal 4051.719 cable ferrules are light-blue, polypropylene insulated end sleeves designed for use with 0.75 mm² conductors. Each ferrule measures 12 mm in length with an outer diameter of 2.8 mm and is supplied in a pack of 500, providing consistent wire end protection and facilitating reliable screw or spring clamp terminations in control panels, switchgear and general electrical installations.

Advantages

These polypropylene (PP) ferrules offer mechanical protection to stranded conductors, reducing the risk of fraying and improving contact consistency in terminal connections. The light-blue colour follows common coding practices to simplify conductor identification. Supplied in a bulk pack of 500, the product supports efficient work on larger wiring projects and maintenance tasks.

Suitable for

• Termination of 0.75 mm² stranded conductors in screw or spring-clamp terminals
• Wiring and maintenance of control panels and switchgear
• General electrical installations where consistent conductor ends are required
• Environments requiring colour-coded ferrules for circuit identification

When it may not be suitable

These ferrules are designed specifically for 0.75 mm² conductors; they are not suitable for significantly larger or smaller conductor cross-sections. The polypropylene insulation and 12 mm length are intended for standard terminal depths and may not fit unusually shallow or deep terminals or specialized connectors designed for different sleeve geometries.

Key specifications

• Conductor cross-section: 0.75 mm²
• Insulation material: polypropylene (PP)
• Colour: light blue
• Length: 12 mm
• Outer diameter: 2.8 mm
• Pack quantity: 500 pieces

How to use

Strip the conductor to the appropriate length so that the bare wire fits fully inside the metal tube of the ferrule without exposed strands. Insert the conductor into the ferrule and crimp using a suitable insulated ferrule crimping tool or bench crimper sized for 0.75 mm² ferrules to achieve a secure, gas-tight connection. After crimping, insert the ferrule-terminated conductor into the terminal and fasten according to the terminal manufacturer's torque specifications.

What to consider before purchase

• Confirm conductor cross-section compatibility: 0.75 mm²
• Verify terminal depth and clamp type to ensure the 12 mm length and 2.8 mm outer diameter are suitable
• Consider colour coding requirements for your installation
• Assess required quantity—pack of 500 may be more than needed for small jobs

Usage recommendations

Use a quality crimping tool matched to insulated ferrules to ensure reliable mechanical and electrical connections. Maintain consistent strip lengths and crimping technique to avoid loose strands and ensure long-term contact integrity in control panels and switchgear.
