Crimp ferrules Rittal AS 4051.597, copper with polypropylene insulation, 8 mm length, 2.6 mm diameter, pack of 5000

Rittal AS 4051.597 crimp ferrules are copper conductor sleeves with a polypropylene (PP) insulated collar, intended for creating defined, reliable terminations on stranded wires. Each ferrule is 8 mm long with a 2.6 mm internal diameter and is supplied in a high-volume pack of 5000 units, making them suitable for repetitive wiring tasks in electrical panels, control cabinets and industrial equipment.

Advantages

These crimp ferrules provide consistent wire-to-terminal connections by enclosing stripped stranded conductors in a copper sleeve that improves contact area and reduces stray strands. The polypropylene insulation collar offers mechanical strain relief and colour stability while resisting mild chemical exposure typical in panel environments. Supplied in bulk, the pack supports efficient workflow for technicians and reduces handling interruptions during large-scale wiring jobs.

Suitable for

• Stranded conductor terminations in control cabinets and switchgear
• Terminal block and relay connections requiring secure crimps
• Mass wiring projects in industrial or commercial installations
• Repair and maintenance tasks where consistent crimp quality is needed

When it may not be suitable

These ferrules are designed for stranded conductors and may not be appropriate for solid-core wires or applications that require soldered terminations. They are intended for standard industrial and panel environments and are not specified for extreme temperature, high-corrosion, or submersion conditions.

Key specifications

• Conductor sleeve material: copper
• Insulation material: polypropylene (PP) collar
• Overall length: 8 mm
• Inner diameter: 2.6 mm (nominal for conductor insertion)
• Pack quantity: 5000 pieces

How to use

Strip the stranded conductor to the appropriate length so the bare strands fully enter the copper sleeve. Insert the conductor into the ferrule until the insulation collar meets the wire insulation. Use a compatible crimping tool sized for 2.6 mm ferrules and apply a single, full crimp to compress the sleeve evenly around the conductor. After crimping, inspect the joint for a secure fit and no loose strands, then connect the ferrule to the terminal block or screw terminal as required.

What to consider before purchase

• Confirm compatibility of the 2.6 mm inner diameter with your conductor cross-section and strand count
• Ensure the 8 mm length fits the terminal depth and available space in your panel or connector
• Verify that polypropylene insulation and copper sleeve materials meet your environmental and electrical requirements

Usage recommendations

Use a dedicated crimping tool matched to the ferrule size to ensure reliable, low-resistance connections. Store the bulk pack in a dry area to preserve the insulation collar condition and handle ferrules with appropriate dispensing aids to speed assembly during high-volume wiring.
