Ferrule Rittal AS 4051.696, copper/polypropylene insulated, 0.75 mm² (AWG 18), 10 mm length, pack of 5000

Rittal AS 4051.696 insulated ferrules are designed for reliable wire termination in industrial and electrical installations. Each ferrule combines a copper conductive barrel with a polypropylene (PP) plastic collar to protect and align stranded conductors. Sized for 0.75 mm² (AWG 18) conductors with a 10 mm insertion length, the pack contains 5000 ferrules to support medium- to large-scale wiring projects and repetitive crimping tasks.

Advantages

These insulated ferrules provide consistent crimp quality by preventing strand fraying and ensuring uniform contact surface for terminal blocks and screw or spring-clamp connectors. The copper barrel offers good conductivity while the polypropylene insulation provides mechanical support and easy handling during assembly. Supplied in a bulk pack of 5000, they reduce workstation re-stocking frequency and are suitable for routine production or maintenance operations.

Suitable for

• Stranded copper conductors with cross-section 0.75 mm² (AWG 18)
• Terminal blocks, screw terminals and spring-clamp connectors requiring ferrules
• Panel wiring, control cabinets and electrical installations in industrial environments
• High-volume crimping in production lines or maintenance workshops

When it may not be suitable

These ferrules are specifically sized for 0.75 mm² (AWG 18) conductors and a 10 mm insertion length; they are not suitable for larger or smaller conductor cross-sections or for applications that require different insertion lengths. For applications with insulation types or environmental requirements that demand specialised materials (for example high-temperature or chemically resistant insulation), a different ferrule material or insulation type should be selected.

Key specifications

• Conductor cross-section: 0.75 mm² (AWG 18)
• Barrel material: copper (conductive)
• Insulation material: polypropylene (PP) plastic collar
• Insertion length: 10 mm
• Pack quantity: 5000 pieces
• Design: insulated ferrule with plastic collar to support stranded conductors

How to use

Strip the conductor to the required length so that the exposed strands match the 10 mm insertion depth. Insert the stripped conductor fully into the copper barrel and crimp using a suitable ferrule crimping tool sized for 0.75 mm² ferrules. After crimping, check that the insulation collar sits flush with the conductor insulation and that the crimped barrel provides a secure mechanical and electrical connection before fitting into terminal blocks or connectors.

What to consider before purchase

• Confirm conductor cross-section and stranded wire type match 0.75 mm² (AWG 18)
• Verify required insertion length (10 mm) is compatible with your terminal or connector
• Ensure a compatible crimping tool for insulated ferrules is available
• Assess whether polypropylene insulation and copper barrel meet environmental and temperature requirements for the application

Usage recommendations

Use a calibrated crimping tool designed for insulated ferrules and the specified conductor size to achieve reliable electrical contact and repeatable mechanical strength. Store the pack in a dry, dust-free location and handle strands carefully to avoid contamination or corrosion before crimping.
