Erko ferrule sleeve TA tin-plated 25 mm² x 15 mm, pack of 50

Erko ferrule sleeve TA tin-plated 25 mm² x 15 mm, pack of 50 is a crimp terminal designed for reliable termination of multi‑strand copper conductors. The tin‑plated steel sleeve provides consistent contact surface, improved corrosion resistance and secure mechanical retention of the conductor strands. Each sleeve measures 15 mm in insulation‑entry length and accepts conductors up to 25 mm² cross‑section, making it suitable for use in electrical panels, control cabinets and industrial wiring where stable, low‑resistance connections are required.

Advantages

The tin plating on the ferrule sleeve reduces oxidation and ensures long‑term electrical conductivity. The uniform inner profile supports compact crimping that prevents strand dispersion and improves the mechanical strength of the termination. Supplied in a pack of 50 pieces, these ferrule sleeves offer consistent dimensions and finish for repeatable, professional results during installation and maintenance.

Suitable for

• Termination of multi‑strand copper conductors up to 25 mm²
• Wiring inside electrical distribution panels and switchgear
• Control cabinet and industrial automation wiring
• Field repairs and preventive maintenance of electrical connections

Key specifications

• Conductor cross‑section: 25 mm²
• Insulation entry / sleeve length: 15 mm
• Plating: tin‑plated surface for corrosion protection
• Material: metal sleeve suitable for crimping multi‑strand copper cables
• Package quantity: 50 pieces

How to use

Strip the conductor to the appropriate length so that all strands fit inside the 15 mm sleeve without exposed wire beyond the plated area. Insert the conductor fully into the ferrule sleeve and position it in a compatible crimp die sized for 25 mm² ferrules. Apply a calibrated crimping force according to the crimping tool manufacturer’s guidance until the sleeve is securely deformed around the conductor. After crimping, inspect the termination for proper compression and for any stray strands; if required, apply heat‑shrink tubing or insulation for additional environmental protection.

Usage recommendations

Use crimping tools and dies recommended for 25 mm² ferrules to achieve reliable electrical and mechanical performance. Store ferrule sleeves in a dry environment to maintain plating condition and avoid contamination prior to installation.
