Cable accessory Rittal 4050.745 — terminal sleeve set (DIN color code)

Rittal 4050.745 — terminal sleeve set (DIN color code) is a cable accessory pack containing insulated ferrules designed for crimping onto conductor ends. Manufactured to DIN color-coding standards, the set provides consistent insulation length and clear color identification for phases and conductor sizes, facilitating reliable connections in control cabinets and electrical panels used in industrial and commercial installations.

Advantages

The terminal sleeves are produced to industry tolerances, ensuring a uniform inner sleeve diameter and insulation fit for standard stranded conductors. Color-coded insulation simplifies wire identification and reduces the risk of cross-connections during installation and maintenance. The sleeves promote secure crimp joints by concentrating conductor strands and improving contact surface area for screw and terminal block connections.

Suitable for

• Crimping onto stranded copper conductors in control cabinets and terminal blocks
• Electrical panel wiring where DIN color codes are required or preferred
• Industrial automation, switchgear assembly, and maintenance work
• Applications that require repeatable, clean conductor ends for screw or clamp connections

When it may not be suitable

The set is intended for stranded conductors and standard wire gauges; it is not suitable for solid single-core conductors that do not require ferrules. It may not be appropriate for extremely high-current conductors or specialized cable types where larger or uninsulated lugs, compression connectors, or welded terminations are specified.

Key specifications

• Insulated ferrules for stranded conductors with DIN color-coded insulation
• Material: tinned copper inner sleeve with insulating collar
• Designed for crimp termination to improve contact reliability
• Range of conductor cross-sections covered by the set (varies by kit composition)

How to use

Strip the conductor insulation to the recommended length for the chosen ferrule. Insert the exposed strands fully into the metal sleeve until the insulating collar meets the conductor insulation. Use a suitable crimping tool matched to the ferrule size and apply a proper crimp to secure the sleeve to the conductor. After crimping, verify the mechanical pull-out strength and electrical continuity prior to final installation in the terminal block or screw connection.

What to consider before purchase

• Confirm the conductor cross-section range in the kit matches the wire sizes used in your installation
• Ensure the ferrule insulation colors and sizes conform to any site or standard color-coding requirements
• Verify compatibility with your crimping tool and termination method
• Consider whether uninsulated or larger lugs are required for high-current connections

Usage recommendations

Use a calibrated crimping tool appropriate for the ferrule sizes to achieve consistent, reliable crimps. After crimping, perform a visual and mechanical check of each termination to ensure the conductor is fully inserted and the insulation collar is flush with the wire insulation. Store the kit in a dry environment to prevent corrosion of the metal sleeves.
