## Summary description

Rittal AS 4051.682 are insulated terminal ferrules for crimping on stranded conductors. Constructed with a copper tube and polypropylene (PP) insulation in white, they suit 0.5 mm² conductor cross-sections and 10 mm tube length. Supplied as a pack of 500 pieces, they provide reliable connections for control cabinets, industrial panels and general electrical wiring.

## Long description

Rittal AS 4051.682 insulated terminal ferrules are designed for crimp termination of stranded conductors in control cabinets, distribution panels and general electrical wiring. Each ferrule has a copper tube for reliable conductivity and a white polypropylene (PP) insulating collar to aid handling and prevent fraying. The ferrules are sized for 0.5 mm² conductor cross-section and a 10 mm tube length, and are supplied in a pack of 500 pieces for larger installation jobs or stock replenishment.
Advantages
These ferrules combine a copper crimping tube with a polypropylene insulated collar to produce a secure electrical and mechanical connection that reduces strand splaying and improves contact consistency. The 10 mm tube length offers sufficient insertion depth for terminal blocks and screw connectors, while the white insulation provides a neutral visual identification. Supplied in a pack of 500, the product supports efficient workflow and reduces the need for frequent reordering on medium to large projects.
Suitable for
 Crimp termination of stranded conductors with a 0.5 mm² cross-section
 Wiring and assembly in control cabinets and industrial panels
 Terminal blocks, screw connectors and relay sockets requiring 10 mm ferrule length
 Electrical maintenance, repair and regular installation work where bulk quantities are needed
When it may not be suitable
This product is intended specifically for stranded conductors with a 0.5 mm² cross-section; it is not suitable for solid conductors or conductors of significantly different cross-section without compromising connection quality. If coloured coding or shrinkable insulation is required for identification or environmental protection, alternative ferrules with different insulation types or colours should be considered.
Key specifications
 Conductor cross-section: 0.5 mm²
 Tube material: copper
 Insulation material: polypropylene (PP), white
 Tube length: 10 mm
 Package quantity: 500 pieces
How to use
Strip the conductor insulation to match the ferrule tube length, insert the stranded conductor fully into the copper tube, and crimp using an appropriate insulated ferrule crimping tool designed for 0.5 mm² ferrules. After crimping, verify that the wire is securely held and that there is no exposed conductor beyond the insulation collar. Install the ferrule-terminated conductor into the terminal block or connector and secure according to the connector manufacturer’s torque recommendations.
What to consider before purchase
 Confirm conductor type and cross-section: suitable for stranded conductors of 0.5 mm² only
 Ensure 10 mm tube length fits the terminal blocks or connectors in your application
 Decide if white polypropylene insulation meets your identification and environmental requirements
 Buy quantity appropriate for the scope of work; this pack contains 500 pieces
Usage recommendations
Use a calibrated crimping tool suitable for insulated ferrules to ensure consistent crimp quality, and follow connector torque specifications to maintain reliable electrical contact. Store the ferrules in a dry environment to preserve insulation properties.
