Terminal ferrules Rittal AS 4051.619 1.0 mm² x 10 mm, copper, polypropylene, red, pack of 500

Rittal AS 4051.619 terminal ferrules are designed for reliable crimp connections on stranded conductors. These ferrules are sized for 1.0 mm² conductors and have a 10 mm metal tube length. The sleeve is made of copper to ensure good conductivity and corrosion resistance, while the insulated collar is injection-moulded polypropylene in red, providing mechanical protection and clear colour coding. The product is supplied as a pack of 500, intended for repetitive wiring tasks in electrical installations and control equipment.

Advantages

The combination of a copper tube and polypropylene insulation offers stable electrical contact and consistent mechanical support when crimped. A 10 mm tube length accommodates reliable insertion of stranded conductors and helps prevent stray strands. The red insulated collar enables quick visual identification and colour-coding in multi-conductor assemblies. Supplied in a bulk pack of 500, these ferrules reduce handling time for larger wiring projects and help maintain uniform termination quality.

Suitable for (tasks / use cases)

• Crimping stranded copper conductors of 1.0 mm² cross-sectional area
• Wire terminations in control panels and switchgear
• Multi-core cable ferrules for terminal blocks and relays
• Electrical installation and maintenance tasks requiring colour-coded terminations

When it may not be suitable

These ferrules are specifically sized for 1.0 mm² conductors and a 10 mm tube length; they are not suitable for conductors of significantly different cross-section or for applications requiring non-insulated ferrules. They are intended for general electrical use and not for high-temperature or corrosive environments unless additional protective measures are applied.

Key specifications

• Conductor cross-sectional area: 1.0 mm²
• Tube length: 10 mm
• Sleeve material: copper
• Insulation material: polypropylene (PP)
• Insulation colour: red
• Pack quantity: 500 pieces

How to use

Strip the conductor to the appropriate length so the bare strands fully enter the 10 mm copper tube. Insert the stranded conductor into the sleeve and position the polypropylene collar against the insulation. Use a suitable ferrule crimping tool calibrated for 1.0 mm² ferrules to apply a single, firm crimp until the tool indicates a complete termination. After crimping, inspect the joint for secure mechanical retention and absence of loose strands. Insert the ferrule into the terminal block or connector and tighten the terminal screw to the manufacturer’s recommended torque.

What to consider before purchase

• Verify conductor cross-section to confirm compatibility with 1.0 mm² ferrules
• Confirm the required tube length (10 mm) fits the terminal or block in use
• Ensure colour-coding (red) matches your wiring scheme or standards
• Check that your crimping tool supports insulated ferrules of this size for reliable terminations

Usage recommendations

Use a dedicated ferrule crimping tool sized for 1.0 mm² ferrules and follow electrical installation torque values for terminal screws. Store the pack in a dry environment to avoid contamination of sleeves and keep the ferrules in their original packaging until use to maintain organisation on-site.
