Crimp ferrule Erko TE 0.25 mm², tin-plated, 100 pcs – TE_0,25-8/100

Erko crimp ferrules TE 0.25 mm² are tin-plated wire end sleeves supplied in a pack of 100. Designed for terminating stranded conductors with a 0.25 mm² cross-section, these ferrules improve electrical contact, prevent conductor fraying and facilitate reliable insertion into terminal blocks and screw terminals. The tin plating offers corrosion resistance and enhances solderability where required, making them suitable for professional electrical panels, control cabinets and general wiring tasks.

Advantages

These tin-plated crimp ferrules provide consistent conductor confinement and reduce the risk of loose strands causing poor contacts or short circuits. The uniform barrel shape ensures repeatable crimp results with compatible crimping tools and dies, while the small cross-sectional size suits fine stranded conductors. Supplied in a pack of 100, they support batch installations and routine maintenance without frequent repurchasing.

Suitable for

• Termination of 0.25 mm² stranded copper conductors
• Wiring in electrical panels and distribution boxes
• Control cabinet and automation system wiring
• Repair and maintenance of terminal block connections
• Small electronics and appliance wiring where secure termination is required

Key specifications

• Conductor cross-section: 0.25 mm²
• Material finish: tin-plated (corrosion-resistant coating)
• Quantity per pack: 100 pieces
• Suitable for fine stranded copper conductors
• Barrel style: closed tubular sleeve for crimp termination

How to use

Strip the conductor insulation to the appropriate length for the ferrule barrel, insert the stranded conductor fully into the ferrule until insulation meets the barrel end, and crimp using a compatible ferrule crimping tool or insulated plier with the correct die for 0.25 mm² ferrules. After crimping, inspect the connection to ensure the conductor is securely held and the crimp is even. Insert the crimped ferrule into the terminal block or screw terminal and tighten to the manufacturer's recommended torque.

Usage recommendations

Use a dedicated crimping tool with the correct die for 0.25 mm² ferrules to achieve reliable electrical and mechanical performance. Avoid reusing ferrules after deformation; replace any ferrule that shows signs of poor crimping or corrosion. Store the ferrules in a dry environment to preserve the tin plating and ensure long-term usability.
