## Summary description

Insulated ferrule sleeve 4/12 from Trytyt supplied in a pack of 100 pieces. These crimp ferrules are designed to terminate stranded wires, providing reliable electrical contact and insulation at connection points.

## Long description

Insulated ferrule sleeve 4/12 by Trytyt, pack of 100 pieces is a set of crimp ferrules designed to terminate stranded conductors and improve the reliability of electrical connections. Each sleeve provides a neat, rigid end to stranded wire, ensuring consistent contact in screw terminals, terminal blocks and control panel connections while offering basic insulation around the conductor entry point.
Advantages
These insulated ferrule sleeves are manufactured to provide uniform crimping and a secure mechanical and electrical connection. The tubular metal barrel ensures low contact resistance and reliable conductivity, while the insulated collar protects against frayed strands and reduces the risk of short circuits. Supplied in a pack of 100, they support efficient installation work and spare part provisioning.
Suitable for
Terminating stranded copper conductors in control panels and switchgear
Connections in terminal strips and distribution blocks
Field wiring in electrical installations and industrial equipment
Improving crimp quality for maintenance and assembly tasks
Key specifications
Ferrule size: 4/12 (sleeve inner geometry for conductor cross-sections compatible with 4 mm² range and 12 mm overall length)
Material: tin-plated copper barrel with insulated collar
Insulation type: collar insulation to protect against strand splay and provide strain relief
Pack quantity: 100 pieces
Intended conductor type: stranded copper conductors
How to use
Strip the conductor to the appropriate length, insert the bare stranded wire fully into the ferrule barrel so that no strands remain outside, and position the insulated collar flush to the insulation. Use a suitable insulated ferrule crimping tool sized for the 4/12 ferrule to perform a single, firm crimp that compresses the barrel evenly around the conductor. After crimping, inspect visually to confirm a secure mechanical hold and correct insulation position before installing the terminated wire into the terminal or connector.
Usage recommendations
Use a calibrated crimping tool matched to the ferrule size to achieve consistent crimp quality. Select ferrules sized to the conductor cross-section to prevent loose or overly tight crimps. Store the pack in a dry environment to avoid corrosion before use. For applications subject to vibration or critical safety requirements, consider checking crimps periodically as part of routine maintenance.
