## Summary description

Rittal AS 4051.612 insulated ferrules for wire termination, with a 0.5 mm² copper conductor and 10 mm length. The ferrules feature polypropylene (PP) insulation in white and are supplied in a pack of 500 pieces. Designed for reliable crimping of stranded conductors to improve connection quality and prevent fraying in control cabinets and electrical installations.

## Long description

Rittal AS 4051.612 insulated ferrules provide a consistent and reliable termination solution for stranded conductors. Each ferrule is designed with a 0.5 mm² copper conductor and a 10 mm barrel length, and is fitted with a polypropylene (PP) insulating collar in white. Supplied in a pack of 500 pieces, these ferrules are intended to improve crimp quality, prevent strand fraying and ensure secure electrical connections in control cabinets, terminal blocks and general electrical installations.
Advantages
These insulated ferrules offer precise conductor guidance and uniform crimping due to the copper barrel and defined length. The polypropylene insulation supports strain relief and prevents shorts where multiple terminations are close together. Delivering a high piece count per pack reduces the need for frequent reordering and supports larger wiring projects. The standardized size and color-coded insulation simplify identification and installation in professional electrical assemblies.
Suitable for
Termination of stranded conductors with a nominal cross-section of 0.5 mm²
Crimping for terminal blocks, relays and connectors in control cabinets
Industrial and building electrical installations requiring consistent, compact terminations
Panel wiring where white insulation color is preferred for visual organization
When it may not be suitable
These ferrules are intended specifically for stranded wires of 0.5 mm²; they are not suitable for solid conductors or significantly larger or smaller cross-sections. They are designed for standard low-voltage electrical terminations and are not rated as a standalone solution for high-voltage insulation or environmental sealing against moisture or corrosive atmospheres.
Key specifications
Conductor material: copper
Nominal conductor cross-section: 0.5 mm²
Barrel length: 10 mm
Insulation material: polypropylene (PP)
Insulation color: white
Pack quantity: 500 pieces
How to use
Select ferrules sized for the conductor cross-section and strip the conductor to the recommended length so the strands can be fully inserted into the 10 mm barrel. Insert the stranded conductor into the ferrule until the insulation collar meets the conductor insulation, then crimp using an appropriate crimping tool or ferrule crimper designed for 0.5 mm² ferrules. After crimping, inspect the joint for a firm mechanical hold and no exposed strands. Fit the crimped ferrule into the intended terminal and tighten the terminal screw to the manufacturer’s torque specification.
What to consider before purchase
Confirm conductor type: designed for stranded copper conductors, not solid wire
Verify the conductor cross-section matches 0.5 mm²
Ensure crimping tool compatibility with 0.5 mm² ferrules
Consider insulation color and length requirements for your wiring layout
Usage recommendations
Use a calibrated ferrule crimping tool for consistent crimps; avoid plier-style crimpers that may not provide the correct compression. Store the pack in a dry, dust-free location and handle ferrules with clean tools to maintain reliable electrical contact. For critical connections, perform a pull test and visual inspection after crimping to confirm proper installation.
